Privacy Policy
dGENwalk ("we", "the app") is a walking game for the dGEN1. Your dGEN1 wallet is your account. This policy explains what data we collect, why, and your rights.
What we collect
- Wallet address. Identifies your account and ties your step receipts, Daily Calls, pool entries and balances to it.
- Daily step totals. Steps are counted on the device from Android's step counter and step detector. Once a UTC day is over, the app sends a step receipt: that day's total, how long you were walking, and whether the count came from the phone or from Health Connect.
- Health Connect steps (optional). If you turn on watch sync, the app reads step records from Health Connect (for example a watch's steps), also in the background when you allow it, to work out the day's total on the device. Only that total leaves the device, inside the step receipt. The app asks for no other Health Connect data.
- Daily Calls. Your higher/lower call, the server's ETH prices at the call and at 00:00 UTC, the steps you had when you called, and the result.
- Contacts (optional, friends board). If you allow contacts, the app reads ethOS contacts on the device and sends only the wallet addresses it finds, to look up their weekly step totals. Names and other contact details never leave the device.
- Device connection grant. Lets the app send step receipts and make calls without a wallet signature each time. It is stored on the device, expires after 14 days without use, and never lasts longer than 35 days after your last wallet signature.
- IP address fingerprint. A one-way HMAC used for abuse prevention and rate limits. On step receipts and calls it is cleared after 30 days; rate-limit data is deleted after 3 hours.
- First-party product and crash telemetry. App open, onboarding, step, call, pool, money, support and crash events, to monitor quality. Wallet and device identifiers are stored as one-way HMAC fingerprints; no advertising ID is collected.
- Region and sanctions screening (pools only). When real-money pools open to the public, your country/region is derived at the network edge to enforce the legal geofence and your wallet address is checked against sanctions lists; the region is not stored. During the allow-listed beta, joining a pool asks for an 18+ confirmation.
What we don't collect
- No location: the app does not ask for location permission, and no GPS tracks exist.
- No name, email, phone number, government ID or photos, and no contact names.
- No advertising IDs, ad SDKs or third-party analytics.
How we use it
- To count your steps toward your goal, your pools and the Daily Call unlock.
- To settle Daily Calls, streaks and the weekly board, and pools (entries, winnings, the fee and payouts).
- To detect step spoofing and abuse (plausibility caps, rate limits, device checks).
- To measure app quality and fix crashes.
What is public
Boards are rankings: the weekly step board and the Daily Call board show weekly totals and right/wrong counts next to shortened wallet addresses. Weekly step totals can be looked up by wallet address, which is how the friends board works.
Sharing
We do not sell, rent or share personal data. ETH prices are fetched from Coinbase and Kraken; no personal data is sent to them. Once sanctions screening is switched on for public pools, the screening provider receives only the wallet address.
Retention
- Step receipts, Daily Calls and pool records: kept while needed for settlement, prizes, safety review, disputes and legal compliance.
- IP fingerprints on receipts and calls: 30 days. Rate-limit data: 3 hours. Internal review logs: 90 days.
- Device connection grants: 14 days without use, and at most 35 days after your last wallet signature.
Your rights
You can delete your account in the app (ME › Delete account; see how). Under GDPR and CCPA you may also request access to, correction or deletion of data tied to your wallet: email support@dgenwalk.xyz. Some records may need to be kept for safety review, disputes or legal compliance.
Children
Not directed at children under 13. Pools and prizes require you to be 18 or older.
Changes
Material changes will be announced in the app and reflected here.
