Tanu is a grocery price scanner. We collect the minimum data needed to run the app, and we never sell it. This page explains exactly what we store, why, and who it is shared with — in plain language.

We do not use your data for profiling, and we do not sell it to anyone.
Third-party services
Tanu relies on a small number of trusted providers. Each has its own privacy policy:
Community sharing
Tanu is built around community pricing. The products, stores, and prices you submit are visible to every other signed-in user, so everyone can compare. Your email address is never shown to other users, and entries are only linked to your account internally.
Retention & deletion
You can edit or delete any product or price you created directly in the app. To delete your account and all personal data linked to it, send a request from the in-app Feedback screen and we will remove it.
Children
Tanu is not directed at children under 13, and we do not knowingly collect their data.
Changes
We may update this policy. Material changes are reflected by the “Last updated” date at the top.
