Privacy Policy

Last updated: 30 September 2026

This policy explains what Yettra does with your data, in plain words. Short version: we use your data only to make the app work for you. We don’t show ads, and we never sell your data.

Who we are

Yettra is made by Zanforge LTD, Griva Digeni 51, Athinaion Court, Flat/Office 202, 8047 Paphos, Cyprus (TIN 60336809G). We are the controller of your personal data. Questions about privacy: [email protected].

What we collect

From Google, when you sign in: your name, email address and profile picture.

What you enter in the app:

your profile: sex, height, age, weight and goal weight, body fat, body measurements;
your goals, reminder times, language and time zone;
your logs: food, water, weight, training, sleep and steps;
day tags (such as mood, fatigue, stress or period) and your own trackers, such as supplements.

From Health Connect, read-only, with your permission: steps, weight, body fat, active calories, exercise sessions and sleep. The app reads the last 14 days when you open it. Yettra never writes anything to Health Connect.

If you choose to send a sync report (Settings → Health Connect → the bug icon), it includes the same data for the last 30 days — values, record times and source apps — plus the app version, phone model and time zone. No report is sent unless you tap Send.

Yettra’s use of information received from Health Connect will adhere to the Health Connect Permissions policy, including the Limited Use requirements.

Photos: pictures of nutrition labels and meals that you take in the app.

Technical data: a push notification token, crash reports, usage statistics that don’t identify you by name, and sync reports you choose to send. Usage statistics include your food searches: the text you type, how many results each group had, and which result you picked, if any.

Why we use it

to calculate your day, your food budget and your analytics;
to recognise food from your text descriptions and label photos;
to send the reminders you set;
to find and fix crashes and keep the service secure;
to improve food search, by seeing what people search for and don’t find;
to find out why data from Health Connect didn’t come through, using a report you sent us.

We don’t use your data for advertising. We don’t sell it or pass it to data brokers.

Legal bases

Your explicit consent for health data. You give it when you sign in, and you can withdraw it at any time by deleting your account. A sync report with health data is only sent after you confirm it separately in the app.
Our contract with you for running your account.
Our legitimate interest in crash reports, keeping the service secure and improving the app with usage statistics.

Who processes your data for us

Railway — servers, database and photo storage, in the EU (Netherlands).
Cloudflare — protects and delivers traffic to our servers.
OpenRouter, and the Anthropic models we use through it — receive only the text you describe a meal with or the label photo you take; for evening picks, only the calories and protein left for the day. Never your name or email.
Open Food Facts — receives only a scanned barcode that isn’t in our own copy of its database. Food search text is never sent to it.
Google — sign-in, and Firebase Cloud Messaging for delivering notifications.
Expo — delivers push notifications.
Sentry (EU, Germany) — crash reports and the Health Connect sync reports you send.
PostHog (EU) — usage statistics: the screens you open and your food searches, linked to your account’s internal id — never your name or email.

Where your data is stored

In the EU. Some of the providers above are US companies; where data leaves the EU, it is protected by the EU Standard Contractual Clauses.

How long we keep it

As long as you have an account. When you delete your account, everything is erased, including your photos. Copies in backups disappear as backups are replaced, and we never restore deleted accounts from them. Crash and sync reports are kept in Sentry for no more than 90 days and then deleted automatically, including after you delete your account. See how to delete your account.

Your rights

You can access, correct, export and delete your data, restrict or object to its processing, and withdraw consent.

Export: in the app, Settings → Account → Export my data.
Delete: in the app, Settings → Account → Delete this account.
Anything else: write to [email protected].

You can also complain to the Office of the Commissioner for Personal Data Protection in Cyprus.

Children

Yettra is not intended for anyone under 18.

Changes

If we change this policy, we update the date at the top. We’ll tell you about important changes in the app.
