The Lingoloom courses are a site for learning Serbian and English. Below is what data it stores and why.
What is stored
- Signing in with Google or Apple. From Google or Apple the site receives and stores the email address, the given and family name from the account, and the account identifier. The identifier lets it recognise you on different devices; the email and name are shown back to you in Settings. If you sign in with Google and with Apple using the same email, that is one account on the site with shared progress. The site does not keep your picture or anything else from the account, and it never sees your password. The email is refreshed at every sign-in.
- Without signing in. If you start without signing in, the site makes a nameless account with no email or name; its key is kept in your browser. This lets you study through your first day. When you sign in with Google or Apple, everything you did without signing in moves into the account and the nameless one is deleted. A nameless account that has not been used for 30 days is deleted together with its progress.
- Learning. The decks and words you took, the review schedule, your answers in exercises (including the text you typed), the words you added yourself, and your settings.
- Remarks. When you send a remark with the bug icon in the header, the site stores its text together with your account and what it is about: the page address, the element's place on the page, its visible text, the size of the browser window and the version of the site. This lets the owner of the site find and fix what you write about. The site takes no screenshot. A remark can be dictated with the microphone button: the microphone turns on only when you press it, the voice recording goes to speech recognition (ElevenLabs, below) and is not stored by the site — only the text comes back into the field, and you send it yourself.
- Hints. Which of the site's hints you have already seen, when, and whether you closed them — so that each is shown once, on whichever device you sign in.
- Visits. The site counts how many times a page was opened in a day: signed in or not, from the home screen or not, and with which source tags from the link you came by (for example from an ad: source, medium and campaign) — as one number a day, without your account, the time, IP address or browser. Sign-ins and nameless accounts are counted per day the same way: how many were made, how many moved into an account at sign-in, how many were deleted. The tags are also written to your account if it was made less than a day ago; if you began without signing in, that is noted at sign-in too. With the dates of lessons this tells the owner how many learners come back; there are no third-party counters on the site. The daily counts are kept for about 13 months (400 days) and then deleted.
- Session. A session key is kept in the browser's local storage; on the server, only its hash. The browser also keeps there your recent deck searches and the source tags of your first visit. There are no advertising or tracking cookies.
- Server log. IP address, time and address of the request, and browser details — to keep the site working and to investigate failures. When the browser asks for the audio of a word, the word itself is part of the request address and ends up in the log. If sign-in is open only to a list of emails, a refusal writes to the log the email that is not on the list.
Who it is shared with
- Apple verifies sign-in with Apple; the sign-in script is loaded from Apple's servers only when that sign-in is on.
- Google verifies sign-in with Google; the sign-in button is loaded from Google's servers. The browser also takes the site's fonts from there, on every page and before signing in: Google sees your IP address when it does.
- ElevenLabs voices the words of the courses, Serbian and English. The text of a word you added yourself is sent there once, to get a recording; it is not linked to your account. ElevenLabs also transcribes a dictated remark: the voice recording is sent there, without an account, and the text comes back.
The data is not sold and not used for advertising.
Deletion
“Sign out” in Settings ends the session on this device. A session that has not been used for 90 days closes by itself. “Delete account” in the site's Settings deletes the account at once, together with progress in every course, your own words, remarks and reminder subscriptions. The account is shared with the Lingoloom translator app, so it is deleted there as well, with its usage records and translation reports; it can also be deleted from the app, and then your learning on this site is erased within a few minutes. If you cannot sign in, write to b-petr-ip@yandex.com. In database backups deleted data stays for about two more weeks.
