Privacy Policy

Last updated: 7 July 2026

This policy explains what information Axlin ("we", "us") collects, why, and what your choices are. It applies to the Axlin desktop application and this website. Axlin is operated by Axlin. Questions? Email support@axlin.app.

1. What happens on your device (and stays there)

Axlin's posture detection runs locally using on-device AI. When monitoring:

• Webcam frames are analyzed in your computer's memory and immediately discarded. No images, video, or face data are saved or sent anywhere.
• Your calibration profile (a small set of numbers describing your posture baseline) and your settings are stored only in a local file on your computer.
• Detection works with no internet connection. You can monitor your posture with your network cable unplugged.

We never receive your webcam feed. It is not technically possible for us to, because the app contains no code to upload it.

2. What we collect

To provide accounts and subscriptions, we process a small amount of information:

• Account details — when you sign in with Google, we receive your email address and a user identifier. We do not receive your Google password.
• Subscription status — whether you are on a trial or an active subscription, and related billing state.
• A device identifier — a one-way hashed fingerprint of your device, used only to prevent abuse of the free trial (e.g. claiming many trials on one machine). It cannot be reversed into your hardware details.
• Support messages — if you email us, we keep that correspondence to help you.
• Waitlist email — if you join the waitlist on this site, we store your email address to notify you about availability.

3. What we do NOT collect

• No video, images, or screenshots — ever.
• No keystrokes, screen contents, or activity outside posture assessment.
• No advertising identifiers, and no analytics or tracking inside the app.

4. Payments

Subscriptions are processed by Stripe. When you subscribe, your payment details are entered directly with Stripe — we never see or store your card number. Stripe processes this information under its own privacy policy.

5. Service providers we rely on

We use a small number of third parties, each only for the purpose listed:

• Google — sign-in (authentication).
• Supabase — securely stores your account and subscription status.
• Stripe — payment processing.
• Cloudflare — website hosting and email routing.
• Formspree — handling waitlist sign-ups on this site.

We do not sell your personal information to anyone.

6. How long we keep it

We keep your account information for as long as you have an account. If you delete your account, we remove your associated personal data, except where we must retain limited records (for example, billing records Stripe or law require us to keep). Local data on your device (calibration and settings) is removed when you uninstall the app.

7. Your rights

You can ask us to access, correct, or delete the personal information we hold about you, or to close your account entirely. Email support@axlin.app and we'll take care of it. Depending on where you live (for example, under GDPR or CCPA), you may have additional rights, including the right to object to certain processing or to lodge a complaint with your local data-protection authority.

8. Children

Axlin is not directed at children and is not intended for use by anyone under 16. We do not knowingly collect information from children.

9. Changes to this policy

If we make material changes, we'll update the date at the top and, where appropriate, notify you. Continued use of Axlin after a change means you accept the updated policy.

10. Contact

For any privacy question or request, email support@axlin.app.

Axlin is a posture-awareness tool, not a medical device or medical service. See our Terms of Service for details.
