Privacy Policy

Staqk ("we", "our", or "us") built the Staqk app as a personal health tracking tool. This policy explains what data we collect, how we use it, and your rights. By using Staqk you agree to this policy.

Medical disclaimer: Staqk is a personal tracking tool, not a medical device or service. Nothing in the app constitutes medical advice, diagnosis, or treatment. Always consult a qualified healthcare professional before making decisions about your health or treatment protocol.

1. What we collect

We collect only what's needed to make the app work.

Account data (cloud-synced users only)

Email address and display name — provided during sign-up
OAuth identifiers from Apple Sign In or Google Sign In

Health & tracking data

Protocol details (compound name, dose, frequency, schedule)
Dose logs (amount, unit, injection site, timestamp, notes)
Daily check-in responses (mood, energy, sleep, and other metrics you choose to track)
Body weight logs
Lab work entries (values and dates you manually enter)
Inventory records (vials, reconstitution logs)

Progress photos

Photos are stored on your device only using the device file system
Photos are never uploaded to our servers or any third-party service
Deleting the app permanently removes all stored photos

App usage data

Feature engagement flags stored locally on-device (e.g. which features you've used) — not sent to our servers
Subscription and purchase status via RevenueCat (see Third Parties below)

2. How your data is stored

Staqk is local-first. All data is written to an on-device SQLite database first. If you create a cloud account, this data is synced to our secure cloud database via PowerSync so you can access it across devices and prevent data loss. Local-mode users' data never leaves their device.

On-device: SQLite database managed by PowerSync
Cloud (if signed in): PostgreSQL database running on dedicated servers we operate in the European Union, reachable only by our own API
In transit: all traffic between the app and our servers is encrypted using HTTPS/TLS
Local-only data: if you use Staqk without an account, your data is never transmitted to us and we hold no copy of it — keeping your own device backups is your responsibility

3. How we use your data

To provide and improve the Staqk app
To sync your data across your devices (cloud accounts only)
To process subscription payments via RevenueCat
To send optional push notifications for dose and check-in reminders — only if you grant permission

We do not use your health data for advertising, profiling, or any purpose other than operating the app.

4. Third-party services

Service	Purpose	Data shared
RevenueCat	Subscription management & in-app purchases	Anonymous user ID, purchase receipts
PowerSync	Local-to-cloud data sync	Your protocol and tracking data (cloud accounts only)
Better Auth	Authentication	Email, OAuth tokens
Apple / Google	Social sign-in (optional)	Name, email (as provided by your Apple/Google account)

We do not sell your data to any third party. We do not use advertising SDKs or analytics tools that profile you.

5. Data retention & deletion

How long we keep your data. If you use Staqk with a cloud account, we retain your account data and your health & tracking data for as long as your account remains open, so that your history stays available across your devices. We do not expire or delete your tracking history while your account is active — it is your record, and we keep it until you choose to delete it.

If you use Staqk without an account. In local-only mode we never receive your data, so there is nothing for us to retain. Your data exists solely on your device.

Deleting your account. You can delete your account at any time from the app: Profile → Delete Account. This permanently and irreversibly deletes all your data from our servers within 30 days.

Data on your device. Your on-device database and your progress photos — which are never uploaded to us — are removed when you uninstall the app.

To request manual data deletion, email us at hello@staqk.app.

6. Children's privacy

Staqk is not intended for use by anyone under the age of 18. We do not knowingly collect data from children. If you believe a child has provided us personal data, contact us and we will delete it.

7. Your rights

Depending on your location, you may have the right to:

Access the personal data we hold about you
Correct inaccurate data
Request deletion of your data
Export your data (available in-app via Profile → Export Data)
Withdraw consent at any time

To exercise any of these rights, contact us at hello@staqk.app.

8. Changes to this policy

We may update this policy from time to time. We'll notify you of material changes via the app or email. Continued use of Staqk after changes constitutes acceptance of the updated policy.
