Privacy
Last updated: 9 November 2026
Short version: No sign-up, no ads, no selling of data. Your learning progress is saved on our own server (alefgo.study) under an anonymous AlefGo ID, so we can improve the course and you can get your progress back on a new phone.
What we save
When you start, the app makes a random AlefGo ID (like K7P2-9QXM). Under this ID our server keeps: the name you typed (if any), your phone's time zone and language (to guess your country), your learning progress and settings, which lessons you finished, the words and letters you often miss, and how many minutes you learn each day. We do not collect your email, phone number, contacts, location or voice.
Why
To see where learners get stuck and make those lessons better, and to let you restore your progress on a new phone with your ID and your 4-picture key. We never sell or share this data, and there are no ads.
Your picture key
The 4 pictures you choose are stored only as a one-way code. After 6 wrong tries, restoring is locked for an hour.
Deleting your data
Email hello@alefgo.study with your AlefGo ID (Profile → Backup) and we delete everything saved under it. Uninstalling the app deletes the copy on your phone.
What the app downloads
To keep lessons up to date, the app asks alefgo.study whether a newer version exists and downloads the changed lesson files. Like any web server, the server may keep standard access logs (IP address, time, file) for a short time for security.
Notifications
If you turn on the daily reminder, it is scheduled on your phone. Nothing is sent to a server.
Speech
Pronunciation plays from audio files inside the app, or from your phone's own text-to-speech. The app does not record your voice.
Children
AlefGo is a general learning app. We do not ask for age and do not knowingly collect more than the learning data above.
