Privacy Policy

1. Who runs this site

Memofluent.com is a personal project; the data operator is D. Niser. Contact: contact@memofluent.com.

2. What we collect

• Account — email and password (the password is stored only as a hash).
• Learning data — decks, cards, progress, courses, settings.
• Session — cookie memo_session (a technical session id, 90 days) and mf_lang (your chosen language).
• Waitlist email — if you left an address in the pricing block.
• Technical logs — standard server records and client errors.

We do not collect payment data, advertising identifiers, or browser fingerprints. There are no third-party ads or trackers.

3. Cookies

Only essential ones: memo_session (login) and mf_lang (language). No analytics or advertising cookies.

4. Email

Transactional emails (verification, password reset) are sent over SMTP. No marketing emails; the only waitlist email is a one-time pricing notice.

5. Usage analytics

To improve the product we log in-service actions of signed-in users (screens opened, study sessions, features used) — pseudonymised by account id, without your name, email or precise location. We keep the events for long-term trends, but we remove the pseudonymous link (account id) from older events after about 13 months, so they become anonymous (we anonymise rather than delete). This is first-party functional data on our own service (legitimate interest) and adds no new tracking cookies. You can switch it off anytime in your profile. Third-party analytics (Yandex Metrica) load only with your cookie consent and can be declined in the banner.

6. Storage and sharing

Data is stored on a server in the EU. We do not sell or share your data with third parties.

7. Data sources & attribution

Example sentences in flashcards come from the Tatoeba project, licensed CC BY 2.0 FR. Country-level geolocation uses the IP-to-Country Lite database by DB-IP (CC BY 4.0); your IP is used only to derive the country and is not stored.

8. Your rights

Request an export or deletion of your data and account — contact@memofluent.com.

9. Mobile app (iOS / Android)

The Memofluent mobile app uses the same account and backend as the website, so everything above applies. App-specific notes:

• Camera & photos — accessed only when you choose to build cards from a picture (e.g. a textbook page). The image you pick becomes your own card content; we do not scan your photo library.
• Study reminders — optional daily notifications are scheduled locally on your device; no reminder data is sent to our servers.
• Offline-first — decks and progress are cached on your device so you can study without a connection; changes sync when you are back online.
• Delete your account — you can permanently delete your account and data right inside the app (Profile → Delete account).

10. Changes

For material changes we update the effective date at the top of this page.
