Privacy Policy
Privacy Policy for Flowstake.com
Last Updated: July 30th, 2026
This Privacy Policy is part of our Terms and Conditions. Please read both documents carefully before using our Platform.
Plain-English Summary: FlowStake collects your GPS location and activity data to verify athletic performance. We use Supabase for database storage, Stripe for payments, and Mapbox for maps. On iOS you can optionally connect Apple Health so your Watch workouts and step counts count toward challenges — that data is used only for fitness features, never for advertising, and never sold (Section 1.5). We do not sell your data to advertisers. Your GPS tracks are only used for challenge verification, and start/end points are trimmed on any map you share. You can export or delete your data at any time.
1. Information Collection
1.1 Required Information
- Email address
- Wallet address
- KYC documentation
- Activity data
- Location data (during activities)
1.2 GPS and Location Data
When you record an activity, FlowStake collects precise GPS coordinates, altitude, timestamps, and derived metrics (speed, pace, distance) for the duration of your session. This data is used exclusively to:
- Verify that your activity meets the challenge completion criteria
- Detect anomalous data that may indicate fraudulent submission
- Generate route maps shown on your activity detail page
GPS tracks are stored in encrypted form in our database. They are never sold to third parties and are not used for advertising. You may request deletion of your GPS tracks at any time; note that on-chain attestations referencing your activity hash cannot be deleted due to blockchain immutability.
1.3 Optional Information
- Profile picture
- Social connections
- Device specifications
- Fitness preferences
- Performance metrics
- Training history
1.4 Health and Wearable Data
FlowStake collects "consumer health data," including precise GPS location,
heart rate, step counts, cadence, and activity/workout metrics. With your
explicit, separate opt-in consent, we may also import workouts from connected
sources you authorize, such as Apple Health (Apple Watch). We collect this data
only after you grant consent in the app and only to provide activity tracking,
challenge verification, and the features you use. We do not sell your health
data, use it for advertising, or disclose it to other users beyond your chosen
sharing setting (your activities default to friends-only and are shown on the
public feed only if you opt in). You can withdraw consent, change sharing, or
delete this data at any time (see Section 4); deletion is completed within 45
days, except for on-chain attestation hashes that are immutable by design. These
practices are intended to align with the FTC Health Breach Notification Rule and
U.S. state consumer-health-data laws (e.g., the Washington My Health My Data
Act). (This section is informational and pending final legal review.)
1.5 Apple Health (HealthKit) on iOS
The FlowStake iOS app can read from, and write to, Apple Health — but only after
you explicitly grant permission in the iOS Health permission sheet. Apple Health
access is entirely optional: FlowStake's core features work using the app's
own GPS recording, and nothing is read from Apple Health unless you turn it on.
What we read (only the types you authorize): workouts, heart rate, step
count, walking/running distance, active energy burned, and workout routes.
What we write: the activities you record in FlowStake, so your workout
history stays complete in Apple Health. We only write activities you actually
recorded — we never write estimated, synthetic, or inaccurate data.
Why we read it: so activities recorded on your Apple Watch or in other apps
count toward your FlowStake challenges, streaks, and step goals, and so heart
rate and distance appear alongside your activity.
Limits we hold ourselves to. Data obtained from Apple Health is used only
for the health and fitness features described above. Specifically, we do not:
- use it for advertising, marketing, or any advertising-related purpose;
- sell it, or share it with data brokers or advertising networks;
- disclose it to any third party without your separate permission, other than
the infrastructure providers listed in Section 3.2 who process data on our
behalf under contract; - use it to train machine-learning models; or
- use it for any purpose other than health, fitness, or activity verification.
Verification note. Activities imported from Apple Health are treated as
lower-assurance than activities recorded live in FlowStake, because any app can
write to Apple Health. Imported activities are labelled as imported and may not
be eligible for verification tiers that require first-party GPS capture.
How to turn it off, and what happens. You can revoke access at any time in
iOS Settings → Privacy & Security → Health → FlowStake, or by disconnecting
Apple Health in FlowStake's settings. Revoking stops all future reads
immediately. Activities already imported into your FlowStake account remain in
your account until you delete them — delete individual activities, or delete your
whole account (Section 4), which removes them. Revoking access in iOS does not,
by itself, delete data already imported.
