Privacy Policy

Weekwise: GLP-1 Tracker · Effective October 12, 2026

The short version: everything you log in Weekwise stays on your phone. There are no accounts and no ads inside the app. We never see, sell or share your health information. From version 1.1, the app tells Meta (Facebook) anonymously when it is installed and when a subscription starts, so we can measure our own ads. Details below.

What you enter and where it is stored

Weekwise lets you log medication doses, injection sites, weight, waist size, side effects, food, protein, fiber, water and your goals. All of it is stored only in a database on your device. It is not sent to us or to any server, and we have no way to access it.

If you delete the app, this data is deleted with it, unless you saved a backup.

Backups and reports you choose to share

You can export a backup file or a PDF report for your doctor. These files are created on your device and go only where you send them (for example iCloud Drive, Files, Google Drive or an email you write). We never receive them.

Reminders

Dose and refill reminders are scheduled on your device using your phone's own notification system. No reminder content is sent to us.

Subscriptions

Weekwise Pro is sold through the Apple App Store or Google Play. They handle payment; we never see your name, card or payment details.

To know whether your subscription is active, the app uses RevenueCat, a subscription service. RevenueCat receives an anonymous app ID created on your device, your purchase history for Weekwise, and basic device information (such as the app version and country of your store account). This is not linked to your name or email and is used only to unlock Pro and to count subscriptions. RevenueCat never receives anything you log in the app. See RevenueCat's privacy policy at revenuecat.com/privacy.

Measuring our ads (version 1.1 and later)

We advertise Weekwise on Facebook and Instagram. To learn which of our ads lead to installs and subscriptions, version 1.1 and later include Meta's software development kit (SDK). It sends Meta:

an anonymous app ID created by Meta's SDK on your device;
that the app was installed and opened;
basic device information, such as device model, operating system and app version, and your IP address;
through RevenueCat, when a free trial starts or a subscription is bought, renewed or cancelled.

Weekwise does not collect your device's advertising identifier (IDFA) and does not ask for permission to track you across other companies' apps and websites. Meta never receives anything you log in Weekwise: no doses, weight, food, side effects or goals. See Meta's privacy policy at facebook.com/privacy/policy.

We also advertise in App Store search. On iPhone, the app uses Apple's own attribution system (AdServices) to tell RevenueCat which Apple Search Ads campaign, if any, led to the install. Apple provides this without any tracking permission and without identifying you. It is used only to count which of our search ads lead to subscriptions.

What we do not do

No account or sign-up, and no email or phone number collected.
No ads shown inside the app, and no tracking across other companies' apps or websites.
No analytics or crash-reporting tools, apart from the ad measurement described above.
We never sell your data, and we never share anything you log.

Children

Weekwise is meant for adults and is not directed to children under 13. We do not knowingly collect information from children.

Your choices

You can edit or delete any entry in the app at any time, or delete everything by deleting the app. Because your logs never leave your device, there is nothing for us to delete on our side. For purchase records held by RevenueCat or ad measurement data held by Meta, contact us and we will request deletion.

Not medical advice

Weekwise is a personal tracking tool. It does not give medical advice, diagnose or treat any condition. Always follow your healthcare provider's instructions.

Changes

If this policy changes, we will update this page and the date at the top.
