Android app

Effective date: October 24, 2026

English Dictionary Offline ("the app") is published on Google Play by the developer Sekirov.

The app uses the internet only to sync your word list, and only if you sign in. Without sign-in it opens no connection at all, and nothing you do in it leaves your phone through the app. If you choose to sign in with Google to sync your word list, the app sends that list to our server (see Word list sync below). After sign-in it connects only to our sync server, api.sekirov.com. It has no ads, no analytics and no tracking, and it does not share or sell any data.

What stays on your phone. The app keeps the words you have searched for, your training progress, the days you practised and your settings (such as the theme) in its private storage on your phone. Unless you sign in to sync your words, no one else, including the developer, can see them. You can remove words from your list on the My words screen or clear the whole list on the About screen, and you can delete everything on your phone by clearing the app's storage in Android settings or by uninstalling the app; words already synced stay on the sync server until they are removed from your synced list or you delete your account, and for the time given below. Cloud backup is turned off for this app, so this data is not copied to your Google account. On some phones, Android's direct phone-to-phone transfer can still copy it to a new phone; your sign-in and your account's name, email address and photo stay on the old phone, so you sign in again on the new one.

Word list sync. If you sign in with Google, your word list is synced through our server, so the same list appears on your other phones and wherever else you sign in with that Google account. You sign in, sign out and delete your account with the account button to the right of the search field. Signing in goes through Google Play services on your phone, under Google's own privacy policy. Google gives the app a sign-in token, and the app sends it to our server; the deletion page below sends one the same way. Besides the number Google gives your account, the token carries your name, your email address and the address of your profile photo. Of these, the server keeps only the number, in coded form. When you sign in, the server uses the address of your photo to fetch the photo from Google and sends it to the app with its answer, keeping no copy; your phone connects only to our server for it. The app keeps your name, your email address and your photo in its private storage on your phone, to show which account you are signed in with, and removes them when you sign out. With each word the server keeps when you added it, when you last opened it, how many times you opened it, your training progress, and a random number that each of your devices makes up for itself, so that copies of the list can be merged. It also keeps the days you practised, so that the number of days in a row is the same on every device. When you remove a word or clear your word list, and the change reaches the server while you are signed in, the server keeps each removed word, marked as removed, for 180 days, so that a device that was not connected removes it too when it connects within that time, and then deletes it; until then the details listed above can stay with the word. When your word list is cleared while you are signed in, the server can keep a copy of the cleared words and their training progress for 30 days, so that they can be restored, and then deletes it. It also keeps a coded form of your sign-in on each device, whether each sign-in came from the app or from a web browser, for a web browser the family of operating system it ran on (such as Windows or Mac, read from the browser's user agent when you sign in; the user agent itself is not kept), the hour each sign-in was last used, and the time of your last sync. The account deletion page shows you this list. The server runs on Cloudflare: Cloudflare sees the IP address of each request, and the server does not store it. Nothing is shared or sold. The app uses Android's permission to connect to the network (INTERNET) for this and for nothing else. Signing out stops the sync, and your words stay on this phone. When your sign-in ends on the server, the app signs you out in the same way, and your words stay on this phone too. On phones without Google Play services the app does not offer sign-in.

Deleting your account. To delete your account, use the delete option in the app, in the same place where you signed in, or open https://sekirov.com/account/delete. Your account stops working at once, and every device signed in to it deletes its word list, its training progress and its practice days the next time it connects, and signs out. The server keeps your word list, your training progress and the days you practised for 30 days: if you sign in again with the same Google account within that time, in any of our apps, your account and its words come back. After 30 days they are deleted for good, and copies in our backups are gone within 30 days after that. So that devices learn of the deletion, the server keeps a coded form of each of those sign-ins, with nothing that links it to you or to your account, until that sign-in would have expired: at most 180 days after the device last synced. A device that does not connect within that time keeps its words, and so does a phone that synced with a version of the app that does not delete them; you can clear them on that device yourself.

Practice reminder. If you turn it on, the app shows one notification in the morning when words in your list are ready to practise. The app works this out on your phone from your list, and nothing is sent anywhere. The app asks you once, at the end of a practice session, whether you want it. It uses two Android permissions for this and for nothing else. Show notifications (POST_NOTIFICATIONS) lets it show the notification. Run at startup (RECEIVE_BOOT_COMPLETED) lets it set the morning reminder again after the phone restarts, because Android clears it when the phone is switched off; the app uses it only while the reminder is on. The app remembers only whether the reminder is on and whether it has already asked you, in its private storage on your phone. To stop the reminder, turn off Practice reminder on the About screen, which opens from the account button, or turn off notifications for the app in Android settings.

Pronunciation. To say a word aloud, the app passes it to the text-to-speech engine installed on your phone. That engine is a separate app with its own privacy policy.

Google Play. The app is installed and updated by Google Play. Google may collect information about installs, and, if you allowed your device to share diagnostics with Google, crash reports, under Google's own privacy policy. The developer sees only the aggregated statistics and crash reports that Google Play Console provides.

Installs from GitHub. The same app is also published as an APK on its GitHub release page (https://github.com/egorsekirov/offline_dictionary/releases), signed with the same Google Play key. If you installed it from there, Google Play did not install it. The app does not check for new versions itself: it connects to the internet only to sync your word list, and only if you sign in. To update, install the newer APK from that page over the one you have. Everything else in this policy applies unchanged.

Children. The app is not directed at children under 13.

Changes. If this policy changes, the new version will be published at this address with a new effective date.

Chrome extension

Effective date: October 26, 2026

The Sekirov English Dictionary extension for Chrome ("the extension") uses the internet to get dictionary cards and practice questions from our server until you download the dictionary, to download the dictionary if you choose to, so that cards open instantly and without the internet, and to sync your word list if you sign in, so that it is the same on your phone. With the dictionary downloaded, cards open instantly, even without the internet. My words works without the internet. It has no ads, no analytics and no tracking.

What it reads on web pages. When you select text on a page, the extension reads the selected text to show its search icon next to it. When you ask for a card (by clicking the icon, double-clicking a word, or using the menu or the keyboard shortcut), it also reads the text around the selection, up to 40 words on each side, to find the phrase the word belongs to. Until you download the dictionary, the extension sends the text you select and the sentence around the selected word to our server so it can find the card in the dictionary; a sentence longer than 50 words is cut to the words around the selected word that a phrase can span. The address of the page and the rest of its text are never sent. The server keeps no record of the text it receives or of who sent it. Once the dictionary is downloaded, the card is found on your computer, and the selection and the text around it are not sent anywhere. The word whose card you open joins My words, and My words goes to the sync server only if you sign in. On pages of sekirov.com, the extension adds a mark with its version to the page, so that the website does not suggest installing it. It adds the mark on no other site. To place a short practice of your words in a page you open, the extension also looks at the page's layout, such as where its headings, paragraphs, lists and video players are, and checks whether the page has a password field. It reads no text for this. None of this is kept or sent anywhere.

Practice questions. Until you download the dictionary, our server builds each practice question. For it, the extension sends the word you are practising, how far you have got with it, up to 60 other words from My words (the wrong answers are drawn from them), whether Chrome can read English aloud and, for a word you practise with a preposition, such as rely on, that preposition. When a practice is offered on a page you open, it also sends the words of that practice, at most five, to check which one may come first. The address and the text of the page are never sent, and nothing that identifies you is sent with these words, whether or not you are signed in. The server keeps no record of them or of who sent them. Once the dictionary is downloaded, practice questions are made on your computer, and nothing about your practice is sent to our server, except that your progress is synced with your words if you sign in.

What stays in your browser. The extension keeps the words you have searched for, with when you last opened each one and how many times, your practice of them (when each word comes back and your answers), and its settings, such as the sites where you turned it or its practice off, in Chrome on your computer. If you download the dictionary, it keeps the dictionary there too; until then, it keeps how long its recent requests to our server took, whether they succeeded and how many it made each day, without the words, so that it can suggest downloading the dictionary when that would make cards open faster. If you sign in, your practice progress is synced with your words, to and from the Android app, and the extension also keeps there the name, email address and photo of your Google account, to show which account you are signed in with, until you sign out; and what it needs to sync: a sign-in token until you sign out, the number our server gives your account, the words waiting to be sent, how far it has synced and when it last synced. Unless you sign in to sync your words, no one else, including the developer, can see them. You can remove words in My words. Removing the extension from Chrome deletes everything it keeps in Chrome; words already synced stay on the server until you delete them (below).

Word list sync. If you sign in with Google, your word list is synced through our server, so the same list appears wherever you sign in with that Google account. Google sends the server a sign-in token, which also carries your name, email address and the address of your profile photo. The server reads from it only the number Google gives your account, which it keeps only in coded form, and the address of your photo: when you sign in, it fetches the photo from Google and passes it to your device without keeping it. It does not keep your name, email address or photo. With each word the server keeps when you added it, when you last opened it, how many times you opened it, your training progress, and a random number that each of your devices makes up for itself, so that copies of the list can be merged. It also keeps the dates of the days on which you practised, so that your number of days in a row is the same on every device. It also keeps a coded form of your sign-in on each device, which kind of client each sign-in came from (the app, the Chrome extension or the website), for the extension and the website the family of operating system it ran on (such as Windows or Mac, read from the browser's user agent when you sign in; the user agent itself is not kept), the hour each sign-in was last used, and the time of your last sync. It shows you this list when you delete your account. The server runs on Cloudflare: Cloudflare sees the IP address of each request, and the server does not store it. Nothing is shared or sold. When you remove a word or clear My words, and the change reaches the server while you are signed in, the server keeps each removed word, marked as removed, for 180 days, so that a device that was not connected removes it too when it connects within that time, and then deletes it; until then the details listed above can stay with the word. When you clear My words, a copy of the cleared words and their progress can be kept in this browser and on the server for 30 days, so that you can restore them, and is then deleted. Signing out stops the sync.

Deleting your account. To delete your account, open https://sekirov.com/account/delete. Your account stops working at once, and every device signed in to it deletes its word list, its training progress and its practice days the next time it connects, and signs out. The server keeps your word list, your training progress and the days you practised for 30 days: if you sign in again with the same Google account within that time, in any of our apps, your account and its words come back. After 30 days they are deleted for good, and copies in our backups are gone within 30 days after that. So that devices learn of the deletion, the server keeps a coded form of each of those sign-ins, with nothing that links it to you or to your account, until that sign-in would have expired: at most 180 days after the device last synced. A device that does not connect within that time keeps its words, and so does a phone that synced with a version of the app that does not delete them; you can clear them on that device yourself.

Pronunciation. To say a word aloud, the extension uses only a voice installed on your computer, so the word is not sent anywhere to be spoken. If your computer has no such voice, the extension does not speak.

Chrome Web Store. The extension is installed and updated by the Chrome Web Store, under Google's own privacy policy.

Children. The extension is not directed at children under 13.

Website

Effective date: October 26, 2026

The Sekirov Dictionary website at sekirov.com ("the website") has no ads and does not need an account. If you sign in with Google, it syncs your word list (below). It uses Cloudflare Web Analytics, Google Analytics and Yandex Metrica to count visits and to see which pages and words people open (below). It collects personal data through these statistics and, if you sign in with Google, to sync your word list or to delete your synced words (below).

What stays in your browser. The words you search for on the website (My words), your theme and your choice about statistics (below) are kept in your browser on this device. When statistics are on, the cookies of Google Analytics and Yandex Metrica are kept too (below). If you sign in, the website also keeps there the name, email address and photo of the Google account you signed in with, to show which account you are signed in with, your training progress and the dates of the days on which you practised, from this website and from your other devices, and what it needs to sync: a sign-in token until you sign out, the number our server gives your account, the words waiting to be sent, how far it has synced and when it last synced. Signing out removes your words, your progress, your practice days and all of this from this browser; your theme and your choice about statistics stay, and so does whether you have seen our suggestions to sign in, to practise and to get the app or the extension. You can remove words in My words; clearing this website's data in your browser deletes all of it.

Searching for words. The dictionary on this website runs on our server: the word or phrase you type, the pages of words you open and, to show their lines, the words in My words are sent to it to be searched. To build a practice question, it also receives the word you are practising, how far you have got with it, the other words in My words and whether your browser can read English aloud. The server keeps no record of what you search for or who searched for it. When statistics are on, Google Analytics and Yandex Metrica receive the address and title of each page you open. Google Analytics receives the words you search for only after you press Search or Enter; Yandex Metrica also records what you type in the search field as you type it, including words you delete before searching, and what each page shows you, such as the words in My words and your practice questions; it does not record the name, email address or photo of your Google account (below). The website checks in your browser whether the extension has marked the page, and sends this nowhere. Until its dictionary is downloaded, the Chrome extension sends the text you select and the sentence around it to the same server so it can find the card, and the words of a practice so it can build its questions (see Chrome extension); the server keeps no record of them either.

Signing in on the website. To sync your word list, the website asks you to sign in with Google. When you choose Sign in with Google, the page opens Google's sign-in page in a window of its own, where you choose your account; if your browser does not open the window, the same tab goes to Google's sign-in page and comes back. Google sends a sign-in token to the website's page sekirov.com/signin/return, which passes it to the page you started from and loads nothing else, and that page sends it to our sync server. Besides the number Google gives your account, the token carries your name, your email address and the address of your profile photo. The server uses only the number, as described under Word list sync. When you sign in, the server also fetches your profile photo from Google and passes it to the page without keeping it. The page takes your name and email address from the token and keeps them in this browser with the photo until you sign out, to show which account you are signed in with.

Cloudflare. The website is served by Cloudflare. To deliver a page, Cloudflare sees the IP address the request comes from, under Cloudflare's own privacy policy. The website itself keeps no record of visits; the statistics below are kept by Cloudflare, Google and Yandex.

Statistics without cookies: Cloudflare Web Analytics. Every page loads Cloudflare's Web Analytics script for every visitor. It counts visits without cookies and stores nothing on your device, so it does not ask for your consent. It sends Cloudflare the address of the page (without the words you search for), the page that sent you here, your country, your browser and device, and how fast the page loaded, under Cloudflare's own privacy policy.

Statistics: Google Analytics and Yandex Metrica. When statistics are on, each page loads the scripts of Google Analytics (Google LLC) and Yandex Metrica (YANDEX LLC). They receive the address and title of each page you open — on a word's page, the word; the words you search for; the links to app stores you follow; that you signed in, without your name, email address or account; the page that sent you here; your browser, device, screen size and language; and your IP address, from which they work out your approximate location. To tell one visit from the next, they keep data in your browser in three places. On sekirov.com, they store cookies: Google Analytics _ga and _ga_<ID>, for up to 2 years; Yandex Metrica _ym_uid and _ym_d, for up to 1 year, and _ym_isad and _ym_visorc, for up to 2 days. In this website's storage in your browser, Yandex Metrica keeps entries whose names begin with _ym, until you turn statistics off or clear this website's data. On Yandex's own domain, yandex.ru, Yandex sets the cookies bh, yandexuid, yuidss, i, ymex and _yasc, for up to 400 days, and on its counter's host, mc.yandex.ru, the cookie yabs-sid, until you close the browser; Yandex can read them on its own services and on other websites that use Yandex Metrica, so it can recognise your browser there. Yandex Metrica also records how you use each page — mouse movements, scrolling, clicks and taps, the page as it is shown to you, and what you type in the search field as you type it, including text you delete before searching — so we can replay a visit and see how the website is used. Yandex stores these recordings in Russia. The recordings hide the name, email address and photo of your Google account. Neither service is used for ads. Google processes the data under its own privacy policy and may process it in the United States. Yandex stores and processes the data in Russia, under its own privacy policy; the European Union has not found that Russia protects personal data adequately. We use the statistics only to improve the website and to see which words people look up. We do not sell them or share them with anyone besides Google and Yandex.

When statistics are on. If you visit from the European Union, the European Economic Area, the United Kingdom or Switzerland, or from a place we cannot tell, the website loads nothing from Google or Yandex until you choose Got it on the cookie notice; scrolling or opening other pages does not turn statistics on. Everywhere else, Russia included, statistics are on from the first page, and Got it only hides the notice. Wherever you are, Cookie settings at the bottom of every page turns statistics off or on again. Turning them off removes their cookies from sekirov.com and Yandex Metrica's entries from this website's storage, and the scripts no longer load. The cookies Yandex set on yandex.ru stay until you clear them in your browser: a website cannot remove another site's cookies. Your choice is kept in this browser on this device. The deletion page at https://sekirov.com/account/delete and the sign-in return page at https://sekirov.com/signin/return have no statistics.

Other sites: Google sign-in and statistics. Fonts and images come from this website itself, except your profile photo, which comes from our sync server when you sign in. When you choose Sign in with Google, Google's sign-in page opens from Google, and Google handles the sign-in under its own privacy policy; the website's pages load no script of Google's to sign you in. Every page except the deletion page and the sign-in return page loads Cloudflare's Web Analytics script, and when statistics are on, the scripts of Google Analytics and Yandex Metrica (above). Pages load nothing else from other sites; links to app stores open only when you follow them.

Cookies and signing in. Signing in sets no cookie on sekirov.com. In Google's sign-in window, Google keeps its own sign-in cookies on its own domains, such as accounts.google.com, under Google's privacy policy; the website does not read them.

Signing in on the deletion page. The page at https://sekirov.com/account/delete asks you to sign in with Google to show that the account is yours. When you choose Sign in with Google, the page opens Google's sign-in page in a window of its own, and Google sends a sign-in token back through sekirov.com/signin/return to the page, which sends it to our server. Besides the number Google gives your account, the token carries your name, your email address and the address of your profile photo. The server uses only the number, to find the words synced to that account, and keeps that number only in coded form; it does not keep your name, email address or photo, and neither does the website. The server also keeps a coded form of this sign-in, as it does for every sign-in; deleting your words ends it, and so does Cancel. The server runs on Cloudflare: Cloudflare sees the IP address of each request, and the server does not store it. Nothing is shared or sold.

Children. The website is not directed at children under 13.
