Privacy Policy
dGENwalk ("we", "the app") is a step-challenge fitness app for dGEN1. The app uses your dGEN1 wallet to identify your account and keep challenge balances accurate. This policy explains what data we collect, why, and your rights.
What we collect
- Wallet address. Used to associate step counts, challenge joins, and balances with your dGEN1 wallet identity.
- Step counts and walking session metadata. Daily step
counts read from the device's
TYPE_STEP_COUNTER,TYPE_STEP_DETECTOR, accelerometer, and gyroscope. Session start time, duration, and approximate distance during a walk session. - Coarse location. Used only during an active walk session for anti-cheat (sanity check that movement is consistent with walking). Not stored beyond the session.
- Contacts, optional and local. If you open the friends leaderboard and grant contacts access, the app reads ethOS contacts on device to find wallet addresses and query public weekly step totals. Contacts are not uploaded to dGENwalk.
- Device connection grant. A per-wallet grant lets your device save walk progress in the background. It is stored encrypted on-device and expires after 14 days.
- IP address fingerprint. Used for abuse prevention, rate limiting, and account safety. Stored as a one-way HMAC fingerprint; rate-limit data is deleted automatically.
- First-party product and crash telemetry. App open, onboarding, walk, challenge, points, premium, support, and crash events are sent to dGENwalk to monitor launch quality. Wallet and device identifiers are stored as one-way HMAC fingerprints; no advertising ID is collected.
- Region (real-money only). For USDC challenges we derive your country/region at the network edge to enforce the legal geofence. We do not store precise location.
- Sanctions screening (real-money only). For USDC challenges your wallet address is checked against sanctions lists.
What we don't collect
- No name, email, phone, government ID, photos, uploaded contacts, or precise GPS tracks.
- No advertising IDs, Meta/Google SDKs, or third-party analytics.
How we use it
- To save verified walk sessions.
- To compute challenge progress, balances, entries, winnings, and payouts.
- To detect step spoofing (sensor fusion + IP rate limit + global device checks and abuse limits).
- To measure onboarding, walk, challenge, payment, support, and crash funnels during launch.
Sharing
We do not sell, rent, or share personal data. Challenge and step records are stored by dGENwalk. Real-money screening providers receive only the wallet address strictly needed for sanctions compliance.
Retention
- Wallet ↔ step day records: retained while needed for challenge settlement, safety review, disputes, and legal compliance.
- Device connection grants: 14 days from issuance.
- Rate-limit data: 180 minutes by default.
- Internal review logs: 90 days.
Your rights
Under GDPR and CCPA you may request access, correction, or deletion of data tied to your wallet. Email support@dgenwalk.xyz. Some records may need to be retained for safety review, dispute handling, or legal compliance.
Children
Not directed at children under 13. Do not use the app if you are under 13. Real-money challenges require you to be 18 or older.
Changes
Material changes will be announced in-app and reflected here. Continued use after changes constitutes acceptance.
