Privacy Policy
Last updated: 5 October 2026
The short version
- Your measurements stay on your iPhone. We do not copy them to our servers.
- We keep only what you need to sign in: your name, your email, an account number and, if you add one, your profile photo.
- We never sell your data and never use it for ads.
- No ad trackers and no usage tracking in the app.
- Take a copy of your readings any time (Settings, Data Backup, Export).
- Delete your account in the app (Settings, Account). Your data is kept out of sight for 30 days in case you change your mind, then deleted for good.
Who we are
Coach Scale is made by Tev Labs, a sole proprietorship owned by Aarooran Ramaswamy Venkatachalam (GSTIN 33BUSPA9343R1ZV), 507, Second Floor, Arvind Towers, DB Road, RS Puram, Coimbatore 641002, Tamil Nadu, India ("we", "us"). "You" means the person using Coach Scale.
Questions, requests and complaints: [email protected]. A person reads every message. This is also our contact under India's Digital Personal Data Protection Act (grievance officer: Aarooran Ramaswamy Venkatachalam).
What stays on your iPhone
Your measurements (such as weight and body composition), your profile, your goals and your settings are stored on your iPhone. We do not receive them. If you back up your iPhone, your backup can include them. Deleting the app deletes them from the app.
What we receive, and why
| What | Why |
|---|---|
| Your name and email, from Apple, Google or the email you type | To create your account and let you sign in |
| An account number we create for you | To tell your account apart from others |
| Your profile photo, if you add one | To show it in the app. It is stored with your account |
If you use Sign in with Apple and choose to hide your email, we only see the private address Apple gives us.
We do not collect your location, contacts, advertising identifier, or any photo other than a profile photo you choose to add.
Apple Health
Coach Scale reads and writes only the data types you allow in Apple Health's permission screen, and you can change that at any time in the Health app. What Coach Scale reads stays on your iPhone. We never delete readings that other apps wrote to Apple Health. Data from Apple Health is never sold, never used for advertising, and never shared with anyone.
Deleting your account does not delete anything in Apple Health. To remove what Coach Scale saved there, use the Health app.
When you log out
So it can welcome you back, this iPhone keeps your first name, how you signed in, and your profile photo. Nothing new is collected. They are removed if another account signs in on this iPhone.
Emails to support
If you contact us from the app, the email can include technical details about the app and your device to help us fix your problem. It never includes your measurements, notes or health answers, and you see the email before you send it.
Who else handles your data
These companies run parts of Coach Scale for us. Each may only use your data to provide its service to us.
| Company | What it does for us | Where |
|---|---|---|
| Supabase | Keeps your account and profile photo, so you can sign in | United States |
| Apple | Sign in with Apple, Apple Health, TestFlight | Apple's terms |
| Sign in with Google (if you use it) | Google's terms | |
| Resend | Sends sign-in codes by email | United States |
| Cloudflare | Our website and support email | Global |
What we never do
- Sell your data, or share it for advertising.
- Use your data to target ads.
- Let a data broker, insurer or employer see your data.
Deleting your account
- Delete it in the app: Settings, Account. Your login is removed right away.
- Your data is kept out of sight for 30 days in case you change your mind, then deleted for good. Copies in our backups are removed after a reasonable period, as the backups age out.
- Within those 30 days, email [email protected] to bring your data back, or to delete it sooner.
- No longer have the app? Email [email protected] and we delete your account for you.
- Apple Health is not touched. Remove what Coach Scale saved there in the Health app.
- Take your readings with you first, if you want them: Settings, Data Backup, Export.
- Signing up again within the 30 days makes a new, empty account. To bring the old one back, email us.
We may keep anonymized data, which can no longer identify you, to improve Coach Scale.
How long we keep it
- Your account (name, email, account number, profile photo) stays while your account exists, and for 30 days after you delete it.
- Emails to support stay in our inbox until you ask us to delete them.
Your rights
Wherever you live, you can:
- See or correct your account details: write to [email protected].
- Delete your account: Settings, Account, or by email.
- Correct or delete your measurements: edit or delete them in the app.
- Take a copy of your readings as a spreadsheet file: Settings, Data Backup, Export. The file is made on your iPhone; you choose where it goes.
- Withdraw consent to Apple Health in the Health app.
- Ask or complain at [email protected]. We answer within 30 days.
In the EU and UK you also have the rights to object, to restrict processing, to portability, and to complain to your data protection authority. In India you may nominate someone to act for you if you die or cannot act. In US states with privacy laws (for example California and Washington) you have the rights those laws give, and we honour them for everyone.
Our legal basis (EU and UK)
Keeping your account so you can sign in is part of our contract with you. Reading Apple Health is based on your explicit consent, which you can withdraw at any time in the Health app.
Data leaving your country
Your account is kept in the United States. For people in the EU and UK we rely on the European Commission's Standard Contractual Clauses, with the UK addendum.
Age
Coach Scale is for people 18 and over. If we learn someone under 18 has an account, we delete it.
Not medical care
Coach Scale is not a medical device and not covered by US health privacy law (HIPAA), because we are not a doctor, hospital or insurer. This policy is what protects your data.
Changes
This is an early version of Coach Scale. When we add features that handle your data differently (for example, keeping your measurements in your account so they reach your other devices), we will update this policy and tell you in the app before the change takes effect.
