Privacy Policy

Last updated: 2026-11-12

Cardavela is a flashcard app. This policy explains what data the app handles. In short: your cards and answers stay on your device, the app has no account, no ads and no tracking.

Data stored on your device

Your decks, cards you type or import, your answers (self-assessments), schedules and settings are saved only in the app's storage on your device. They are not sent to us. iOS may include them in your device backup (iCloud or computer) under your own Apple settings.

Downloading decks

When you download a deck, the app requests the deck file from our server over HTTPS. Like any web server, it receives your IP address and the standard request headers in its access logs for security and abuse protection. Logs are not linked to an identity, are not used for advertising and are deleted on rotation (typically within 30 days). No account, device identifier or answer data is sent.

Links and imported files

If you open a deck from a link, the app downloads that file from the address you entered. Files you import are read on your device only.

Speech

Pronunciation uses the voices built into iOS on your device. Cardavela does not record or upload audio.

Website and online study

On cardavela.dev, online study progress is saved only in your browser's local storage on your device. It is not sent to us. Clearing the site data in your browser deletes it. The site is hosted on Vercel, which keeps standard request logs for security.

Analytics, ads and tracking

Cardavela contains no third-party analytics, advertising or tracking SDKs and does not track you across apps or websites.

Backups you export

A personal backup is a file you create and keep. It contains your decks and answers. Share it only with people you trust.

Children

The app does not knowingly collect personal data from anyone, including children.

Purchases

The app is free today. If paid decks appear later, payments are processed by Apple; we receive no payment card details.

Your choices

Delete a deck in the Library or delete the app to remove all data stored by Cardavela on your device.

Changes and contact

We will update this page when the app changes how it handles data. Questions: contact support.
