Privacy policy

Effective 13 November 2026 · Tailwhale iOS app and tailwhale website · Developer: Tinkerer (Pratik Poddar)

The short version

Tailwhale has no accounts. We don't ask for your name, email or phone number, we don't track you across apps or websites, we don't show ads, and we don't sell or share personal data.

What the app stores on our server

• An anonymous device ID and secret. Created on first launch so the app can save your settings. The secret stays in your iPhone's Keychain; we keep only a one-way hash of it.
• Your push notification token (only if you allow notifications), your time zone, app version and a count of app opens (used for referral grants). The token is used only to send the alerts you turned on.
• Your follows and mutes: the public wallet addresses you follow, whether push is on for each, and the markets or categories you muted.
• Your referral code and, if you entered a friend's code, the link between the two anonymous devices and the Pro days granted.
• Subscription status. If you subscribe, the app sends Apple's signed transaction to our server so Pro works server-side. We store the product, transaction IDs, trial flag and expiry date. Payment is handled entirely by Apple; we never see your card or Apple ID.
• Usage counters for free-tier limits, e.g. which trader you backtested today.

What we don't collect

No wallet connection, no private keys, no seed phrases, no trading, no location, no contacts, no photos (share cards are made on your phone; saving one to Photos uses Apple's share sheet), no analytics or advertising SDKs.

Public market data

Trader rankings, positions, trades and prices come from Polymarket's public Data API. Wallet addresses and trades on it are public blockchain data. Tailwhale shows them with derived analytics; it does not link a wallet to a real person, and "Unusual activity" describes a trade, not a person.

Where data lives and for how long

Server data is stored with Supabase (database) and Netlify (API and website hosting). Like any web host, they process your IP address in standard request logs; we don't store it in Tailwhale's database. We keep device data while you use the app and delete it on request. Push tokens that Apple reports as invalid are removed automatically.

Your choices

Turn notifications off in iOS Settings. Unfollow or mute in the app. To delete your device's data, email us your referral code (shown in Settings) and we'll delete everything tied to that device.

Children

Tailwhale is rated 17+ and is not directed to children.
