Privacy Policy
What we collect
We collect your email address (from your OAuth provider), your OAuth provider account ID, any proofs you log, and any profile information you provide (name, bio, username). We also collect anonymous analytics events (page views, feature usage) via PostHog.
What we never collect
Longevity CLINICAL proofs are enforced as private at the database level — they are never visible to other users or stored in public feeds. We do not collect payment information unless you purchase a paid program (Stripe handles all card data).
How we use it
Your data is used to show your progress, connect you with cohorts, and generate your public proof record at powstik.com/{your-handle}. We send transactional emails (welcome, achievement unlocked) via Resend. We do not use your data to train AI models or sell it to third parties.
What we never do
- Sell your data — ever
- Run ads — ever
- Share your data with employers without your explicit consent
- Show Longevity CLINICAL data to anyone other than you
Data deletion
You can delete your account from your account settings. Deletion removes your profile, email address, all proofs, enrollments, and identifying information immediately and permanently.
Credential records are retained anonymously. Verified Outcome Cards and path credentials you earned are kept as permanent anonymized records attributed to “Former Powstik Builder” — not your name or handle. This preserves the integrity of the verified credential network while fully erasing your identity from the platform. Credential embed URLs continue to resolve. You can request removal of specific credential records by emailing privacy@powstik.com.
Snapshots shared to third-party platforms (LinkedIn, Twitter) before deletion cannot be retroactively removed from those platforms.
