Privacy policy

Gramday for iPhone · Last updated 16 October 2026

Short version: Gramday has no account and no server that holds your records. Your doses, weight, side effects, meals, water and notes stay on your iPhone. There are no ads, no analytics and no tracking.

What stays on your iPhone

Everything you log in Gramday is stored only on your iPhone: your medicine and doses, side effects, weight, meals and meal photos, products you save, water, notes, reminders and settings. We do not receive this information and cannot see it.

What leaves your iPhone

Only four things are sent to other services, and only for the reason given. None of them includes your name, email, doses, weight, side effects or notes.

  • What
    A meal photo, or a photo of a product's nutrition label, only when you choose to take one. The app makes the photo smaller first.
    To whom
    Google (Gemini, through Firebase)
    Why
    To estimate the food and protein, or to read the numbers printed on the label. The photo travels with a fixed instruction. Label photos are deleted from your iPhone right after reading; meal photos stay with your meal on your iPhone. Google may keep requests for a limited time to detect abuse. Every result is labelled as an estimate and you can change it.
  • What
    A barcode number, only when you scan a product.
    To whom
    Open Food Facts (a public food database)
    Why
    To look up the product's nutrition.
  • What
    Your subscription record: trial, renewal and expiry, tied to a random ID.
    To whom
    Apple and RevenueCat
    Why
    To know whether your plan is active. Apple takes the payment. RevenueCat does not receive your name or email, and it never sees your health log.
  • What
    A device check (a token, not your data).
    To whom
    Google (Firebase App Check)
    Why
    To confirm that requests come from the real Gramday app.

These services have their own privacy policies. We send them only what is listed above, and we do not share your information for advertising.

What we do not collect

  • No account, name, email address or phone number.
  • No location, contacts or browsing history.
  • No analytics, crash-reporting or advertising tools in the app.
  • No tracking across other apps or websites, and no advertising identifier.

Reminders and widgets

Reminders, including the optional second reminder when a dose is not logged yet, are created on your iPhone and are not sent through our servers. Reminder text and widgets never show your medicine's name, your dose or your weight.

Reports you create

PDF reports and data exports are made on your iPhone. They leave it only when you choose to share, save or print them, for example to send to your clinician. Once shared, the copy is handled by the app or person you send it to.

Keeping and deleting your data

  • Export: in Settings, open Your data, then Reports and export, to save a copy of your log somewhere safe, such as Files.
  • Delete: in Settings, open Your data, then Delete all data, to erase everything from your iPhone. Deleting the app also erases it.
  • An iPhone backup may include a copy of your data. Don't rely on a backup as your only copy; use Export.
  • Delete all data erases what is on your iPhone. It cannot recall photos that were already sent to Google for an estimate, or Apple's and RevenueCat's subscription records.

Because we hold none of your health records, there is nothing for us to look up or delete on our side. If you want to ask about subscription records, write to us (see Contact).

Who it is for

Gramday is for adults aged 18 and over. It is not intended for children, and we do not knowingly collect information from them.

Not medical advice

Gramday records what you tell it. It does not give medical advice, diagnose or treat any condition, and it does not change your medicine. Follow your prescriber's and the medicine leaflet's instructions. If a symptom is severe or worrying, contact your clinician or emergency services.

Changes to this policy

If this policy changes, we will update the date at the top and describe the change in the app's update notes when it affects what leaves your iPhone.

Contact

Questions about privacy: support@gramday.app. If you use Contact us in the app, the email it prepares includes the app version and the iOS version to help us answer; nothing is sent until you send the email yourself.
