This policy explains what personal data ADHERO collects, how it is used, and your rights under UK GDPR. ADHERO Systems Limited is the data controller.
When you create an account: name (display name), email address, password (stored as a secure hash — we cannot read it). When you use the app: daily ritual completions, training session logs, weekly plans and Quiet Day selections, journal entries, weekly reflection responses, adherence scores and streak data, notification preferences and push subscription tokens, last active timestamp. Automatically: device type for PWA detection, time zone for quiet hours and notification scheduling.
We use your data to: provide the ADHERO service; show your coach the signals they need to support you (adherence scores, flags, reflections where shared); send you push notifications based on your preferences and chosen tone; improve the product based on aggregated, anonymised usage patterns. We do not sell your data. We do not use your data for advertising.
Your coach: if you are a client, your coach can see your adherence score, ritual activity, weekly reflections (if you submit them), and any flags raised by the system. They cannot see your journal entries. Stripe: payment processing only. Replit: the platform ADHERO is currently hosted on, with data stored within EU infrastructure. We do not share your data with any other third parties.
We retain your data for as long as your account is active. If you delete your account, your personal data is deleted within 30 days. Anonymised aggregated data may be retained for product improvement purposes.
Under UK GDPR you have the right to: access the personal data we hold about you; correct inaccurate data; delete your data; restrict how we process your data; port your data to another service; object to processing based on legitimate interests. To exercise any of these rights, contact us at ryancowie04@outlook.com. We will respond within 30 days. You also have the right to lodge a complaint with the Information Commissioner's Office (ICO) at ico.org.uk.
We take reasonable technical measures to protect your data, including encrypted passwords, HTTPS-only access, and access controls on the database. If you suspect a breach, contact us immediately.
ADHERO uses a session cookie to keep you logged in. We do not use tracking cookies or third-party analytics cookies.
We may update this policy from time to time. We will notify you of material changes by email or in-app notification.
