Getting in touch

To help us answer quickly, include: your device model and iOS version, the app version, what you expected to happen and what happened instead, and — if it concerns an assistant answer — the approximate time of the conversation. Please do not send screenshots containing information you would rather not share.

Frequently asked questions

How do I get the app?

Meyuman is not published yet. Coming soon on the App Store — the link will appear here and on the home page once the app is published. If you are already testing a build through TestFlight, it continues to work as usual.

Is there a web version?

No. The public web version was discontinued when this site went live. Meyuman will be available as an iOS app only.

Do I need an account?

No. There is no registration, no login and no password. You open the app and start.

Where is my data stored?

On your device, in the app's own storage. We have no copy of your diary and cannot see it; only the parts needed for an assistant request or a PDF report are sent for processing. Full detail is in the Privacy Policy.

What happens if I delete the app or change my phone?

Everything is lost permanently, and we cannot restore it — we never had a copy. Before changing or resetting a device: Settings → Export data, and save the JSON file. On the new device: Settings → Import data.

How do I delete everything without deleting the app?

Settings → Reset all data. It requires a double confirmation and cannot be undone.

Is my meal photo uploaded?

A compressed copy is sent so the assistant can analyse it, and passes from there to Google for processing. It is not stored on our server. The full-resolution original does not leave your device. See section 14 of the Privacy Policy for the terms under which Google processes it.

Is my chat stored on your server?

No. Recent messages are sent as context with each request and are not kept afterwards. The finished answer is kept for up to 15 minutes only so that a retried request gets the same answer, and is then deleted automatically. Beyond that we keep 👍/👎 ratings (metadata only, without any text) and technical usage counters — see section 9 of the Privacy Policy.

How do I remove a rating?

Tap it again. If you want every rating from your device removed, email us with the ct_client_id value from your exported JSON file — without it we cannot find your rows.

Are the calorie numbers accurate?

They are estimates. A photo or a short description cannot convey exact portion size, oil, sugar or preparation method — treat every figure as an approximation.

The assistant got something wrong. What do I do?

Correct the entry in the diary — you can also simply tell the assistant in the chat and it will update the record. Tap 👎 so that we can see it, and write to us if it keeps happening.

Is this medical advice?

No. It is a diary, not a clinical tool, and it gives no medical or dietary advice. Consult a qualified professional before making health decisions. See the Terms of Use.

Can I use it on more than one device?

Not at the same time — there is no synchronisation. You can move your data with Export and Import.

What is the minimum age?

18. It is a condition of use that you confirm, not a technical check the app performs.
