<aside> 🔒

Short version: UPTALL has no accounts and no sign-up. Your height, weight, parents' heights, measurements, workouts and nutrition logs stay on your iPhone. We never see them and we never sell data to anyone. The only thing we receive is anonymous usage statistics, which you can switch off in the app.

1. Who we are

UPTALL is developed and published by Ahmet Buğra Kaçdı, an individual developer based in Istanbul, Türkiye ("we", "us", "our"). For the limited data described in this policy, we act as the data controller.

2. Data that never leaves your device

UPTALL works without an account. Everything you enter is written to a private database inside the app's own sandbox on your iPhone. It is not uploaded to us, and there is no cloud sync or backup on our side:

• Your profile: date of birth / age, gender, current height, weight, your father's and mother's height, and your activity, nutrition and sleep answers
• Every height and weight measurement you log, with its date
• Your workout history, streaks, levels, achievements and daily nutrient check-ins
• Your app settings: units (cm/kg or ft/lb), reminder times, sound and analytics preferences
• Height predictions and progress charts, which are calculated on the device

A small summary (streak count and today's progress) is shared with the UPTALL home screen widget through a private App Group container. That container is on the same device and is not readable by other apps.

This data is included in your iPhone backup if you back up your device to iCloud or a computer. Those backups belong to you and are governed by Apple's terms, not ours — we have no access to them.

You can erase everything at any time: Settings → Data → Reset all data, or by deleting the app.

3. Data we do receive

3.1 Anonymous usage analytics

To understand which parts of the app people actually use, UPTALL sends anonymous product analytics to Mixpanel. Events are tied to a random identifier generated on your device — not to your name, email, Apple ID or advertising identifier.
