WayScalePrivacy Policy
Last updated: November 10, 2026
WayScale is a weight-loss tracker made by Ali Farhangi, an individual developer ("I", "me"). This policy explains what the app keeps, what it sends, and what it never sends. The short version: your weight and health data stay on your iPhone. There is no account and no WayScale server.
What stays on your iPhone
Everything you enter or the app reads is stored only on your device, in the app's own storage:
- Your weigh-ins and the 7-day average
- Your height, date of birth, sex, goal weight, pace and plan
- Your onboarding answers, including pregnancy and breastfeeding answers
- Your daily step totals read from Apple Health
- The flags you've passed and your conversations with the guide
Answers about your menstrual cycle are used for that one conversation and never stored. None of this is sent to me or anyone else. WayScale does not sync it to iCloud. Your device's own backups may include it, protected by your Apple ID.
Apple Health
If you allow it, WayScale reads and writes body weight and reads step count. Data from Apple Health is only used to show your progress inside the app. It is never used for advertising or analytics, never sold, and never leaves your device through WayScale. You can change access at any time in the iPhone Settings app → Health → Data Access & Devices → WayScale.
Anonymous usage analytics
To learn which parts of the app help people and where they get stuck, WayScale sends anonymous usage events to PostHog, an analytics service, on servers in the United States. Each install gets a random ID. It is not your name, email, Apple ID or advertising ID, and it can't be linked to you.
| Sent | Never sent |
|---|---|
| Which onboarding screens you view and finish. Whether you finished or skipped the intro. | Weight, height, age or date of birth |
| Some onboarding answers: your main reason, what you've tried before, what made you stop, your sex, day type, the step goal and pace you chose | Pregnancy, breastfeeding and cycle answers |
| Whether you allowed notifications | Calorie targets |
| Trial and paywall screens viewed, the plan you selected, and whether a trial started, converted or was cancelled | Step counts or anything from Apple Health |
| Guide conversations shown and their outcome type. Flags passed. Share cards shown and shared. Story fragments unlocked. Whether the morning reminder is on. Reaching the summit. | Your answers to the guide about eating or periods |
Session recording is off. IP addresses are discarded and not used to work out your location. Nothing is used for advertising or shared with data brokers, and WayScale does not track you across other apps or websites.
Subscriptions
Purchases are handled entirely by Apple. I never see your payment details, name or Apple ID. Apple tells the app only whether your subscription is active.
Notifications and calendar
The morning weigh-in reminder and the trial reminder are local notifications scheduled on your iPhone. They are not sent from a server. If you choose "Add a reminder to your calendar", WayScale adds one event and cannot read your calendar.
Photos
If you tap Save on a milestone card, WayScale adds that image to your photo library. It cannot see your other photos.
Children
WayScale is for adults. People under 18 can't get past onboarding, and I don't knowingly collect anything from children.
Deleting your data
In WayScale, go to Settings → Delete all data, or delete the app. Data you saved to Apple Health stays there until you remove it in the Health app. The anonymous analytics events can't be traced back to you. If you'd like them removed anyway, email me with the date you installed the app and I'll do my best.
Your rights
Depending on where you live, you may have the right to access, correct or delete personal data, or to object to its use. Because WayScale keeps your data on your device, you control it directly. For anything else, email me.
Changes
If this policy changes, the new version will be posted here with a new date.
