Cancellations, trials, and refunds: these flow through Apple and Google directly.
Subscriptions are managed through your Apple ID or Google Play account, not from inside Hairmony.
Settings → [Your Name] → Subscriptions → Hairmony → CancelPlay Store → Profile → Payments & subscriptions → Subscriptions → Hairmony → CancelYes, your subscription converts to a paid plan at the end of the trial unless you cancel before it ends. We'll send a reminder 2 days before the trial converts so you have time to decide.
Refunds for App Store and Play Store purchases are handled by Apple and Google directly, not by us.
Hairmony has no accounts. Almost everything stays on your device.
The fastest path is the "Delete my data" button inside the App, under Settings. Tapping it instantly erases your hair profile, scan history, routine, locally stored photos, and your anonymous analytics ID from your device. If you keep using the App afterwards, analytics starts a fresh profile; your subscription and Support ID are kept.
For data held off-device (our server records, RevenueCat subscription records, PostHog analytics events, Meta and Google ad-measurement events, Anthropic scan photos within their 30-day window), email hairmonyapp@gmail.com with the subject "Data deletion request" and we'll forward the request on your behalf. Include your Support ID (Settings → My Account → Support ID) so we can find your records on our server, at RevenueCat, and at PostHog. We respond within 30 days as required by the GDPR.
Your hair profile, scan history, routine, and photos live on your device. We operate no servers that hold your photos, answers, or routine. Photos, together with your hair profile answers on a hair scan, are sent to Anthropic only while a scan is running, and only after you allow AI photo analysis, which you can switch off any time in Settings → Privacy. Our EU server keeps an anonymous ID, your scan allowance, and a copy of each AI result for 7 days, and subscription state is managed by RevenueCat. Usage analytics (PostHog, EU Cloud) and ad measurement (Meta and Google) are optional: off until you switch them on, except on devices set to the US, where they start on. You control both in Settings → Privacy.

How scans work, what the scores mean, and why your results are yours.
Hairmony evaluates 9 hair traits unique to each scan. Even people with very similar hair types can end up with quite different profiles, depending on porosity, scalp condition, damage level, and other factors that aren't visible at a glance.
We recommend rescanning every 6–8 weeks to track changes in your routine. Hair changes too slowly to see real differences day-to-day.
A low compatibility score doesn't mean the product is bad. It means it may not be optimised for your specific traits. Trust your own results. Hairmony is a guide, not a verdict.
We don't have commercial relationships with any brand. Products are scored on ingredient compatibility only.
If you'd like to suggest a brand for our database, email hairmonyapp@gmail.com. We'd love to hear it.
We read every message. Drop us a line and we'll get back to you within 24 hours.
