Privacy Policy
This policy explains what Aethos Solutions LLC ("we", "us") collects when you use the Skyyn app and the skyyn.app website, what we do with it, who processes it for us, and how to delete it.
The short version. Your photos are stored privately in your account, sent to our AI providers only to produce your results, and never sold or used for advertising. You can erase them at any time. A plain-language guide to your photos sits alongside this policy; if the two ever differ, this policy governs.
1. Information we collect
Information you give us
- Account details. Your email address, an optional display name, and the sign-in provider you used (Apple, Google or email).
- Profile answers. Skin type, age range (we keep only the range, never your age), the goal and concerns you choose, and how many products you use.
- Photos. The selfies you submit for scoring and the product photos you submit for label reports. The app uploads a single still image that you approve. It does not record or upload video, and it does not use the microphone.
- Scan results. Your Skyyn Score, sub-scores, the observations made about each photo, and photo-quality measurements.
- Routine and shelf. The routine steps you write and tick off, the products you add (name, label text, ingredients, and any price or purchase date you enter), and the product events you log.
- Notes and messages. Notes you attach to scans, your conversations with Skyyn Coach and any Coach answers you report, reports you file about catalogue records, and messages you send to support.
- Invitations and cancellations. If you use an invite code, the link between your account and the person who invited you. If you cancel Skyyn Pro in the app, the reason you choose.
Information collected automatically
- Device and app data. Device model, operating system version, app version, language and time zone, and a device attestation used to confirm that requests come from a genuine copy of the app.
- Usage data. Which features you use and when, collected with Google Analytics for Firebase. We have switched off advertising identifier collection and ad personalisation in the app. Like any online service, our providers see your IP address when the app connects.
- Crash and performance data. Crash reports and performance traces collected with Firebase Crashlytics and Firebase Performance Monitoring. Crash reports can include a flag showing whether the device appears to be jailbroken or rooted.
- Notification token. If you allow notifications, a token that lets us deliver them to your device.
- Purchase records. Which Skyyn Pro plan you hold and its status, received from Apple or Google. We never receive your card details.
We do not ask for your location, your contacts or your advertising identifier.
2. How we use your information
- To produce your Skyyn Score, sub-scores, observations, label reports, routine suggestions, recaps and Coach answers.
- To show your history, trends and before and after comparisons.
- To personalise suggestions using your profile answers.
- To run your account and subscription, prevent abuse and enforce usage limits.
- To send notifications if you allow them: the reminders you set, progress updates, recap notices and occasional reminders to come back and scan. We do not send advertising for other companies' products.
- To reply to you when you contact support.
- To understand, in aggregate, how the app is used and to fix faults.
- To check and improve the scoring using measurements and scores. We do not use your photos to train AI models.
3. Photos
When you submit a photo it is uploaded over an encrypted connection and checked: a selfie must be a real photo of one face, and it is screened for unsafe content. It is then analysed to produce your result and stored privately in your account.
Scan photos are kept while your account exists so that the app can show your history and compare scans. You can erase them at any time with Start over or Delete account in your account settings. A photo that was turned away for a retake is kept with your scan history until you erase it.
If you take a scan before creating an account, the photo and result are held so they can move into your account when you sign in. If you do not sign in, they are deleted automatically within about 8 days.
A score you choose to share creates a public page that contains only the Skyyn Score and the four sub-scores. It never contains your photo, your name, your email or your observations.
We do not sell your photos, use them for advertising, or use them to train AI models.
4. Who processes your data for us
We use the following service providers. Each receives only what it needs to do its job.
| Provider | What it does | What it receives |
|---|---|---|
| Anthropic (Claude) | Analyses photos to produce scores and label reports; writes routine suggestions, recaps and Skyyn Coach answers. | The photos you submit, your scan results and profile answers, your routine, shelf, notes and recaps, and the messages you send to Coach. |
| Google (Gemini) | Backup for scan scoring if the primary provider is unavailable. | The photo being scored. |
| Google Cloud Vision | Detects the face in a selfie and screens it for unsafe content. | The selfies you submit. |
| Google Firebase and Google Cloud | Sign-in, database, private photo storage, server functions, notifications, analytics, crash and performance reporting, and website hosting. | Your account data and content, stored in the United States. |
| Resend | Delivers sign-in codes, email-change confirmations and support emails. | Your email address and the content of the email. |
| Apple and Google | Sign in with Apple or Google; App Store and Google Play billing. | What is needed to sign you in and to confirm your purchase. |
| Expo | Delivers app updates. | Device and app version information. |
When Skyyn Coach looks something up, the search is run by Anthropic's web search tool against a fixed list of medical and public health websites. The search query is derived from your question.
We do not sell your personal information, and we do not share it for cross-context behavioural advertising.
5. Amazon links
The Discover section of the app shows products that are sold on Amazon. Skyyn takes part in the Amazon Services LLC Associates Program, an affiliate programme. When you tap through, you leave Skyyn, and Amazon receives your IP address and device information under its own privacy policy. We receive commission reports from Amazon that do not identify you or what you bought. We do not send Amazon any of your Skyyn account data.
6. How we protect your data
- Data is encrypted in transit and at rest.
- Database and storage rules allow each account to read only its own records.
- Scores and other generated content can be written only by our servers, never from a device.
- Requests from the app to score photos, read your data or change your account must come from a verified copy of the app.
- Sign-in tokens are kept in the device's secure storage.
No system is perfectly secure. If we learn of a breach that affects your data, we will tell you as the law requires.
7. How long we keep it
- Account data, scans, photos, routine, shelf and Coach conversations: while your account exists.
- Coach conversations: the most recent 80 messages. Older ones are removed as new ones are added, and you can clear the history at any time.
- Scans taken without an account: about 8 days at most.
- Uploads that were never turned into a scan or product: removed within about 3 days.
- When you delete your account: your account and the content in it are erased from our database and storage straight away. Any copies in backups are overwritten within 90 days. Messages you sent to support, and the record that you invited another user, are kept separately.
- Purchase records may be kept longer where tax or accounting law requires it.
8. Your choices and rights
- Delete. Delete account, in your account settings, erases your account and the content in it. Start over erases your scans, photos, notes, routine, shelf, Coach conversations, recaps, share links and profile answers. It keeps your account, your sign-in and Skyyn Pro.
- Access and copy. Email support@skyyn.app from the address on your account and we will send you a copy of the data we hold about you.
- Correct. Edit your profile in Settings, or ask us.
- Notifications. Switch reminders off in the app's notification settings, or switch all notifications off in your device settings. Turning off the scan reminder also turns off progress and come-back notifications.
- AI processing. The app asks for your agreement before your first photo or Coach message is sent to our AI providers. If you decline, those features stay off.
Depending on where you live, you may have further rights, for example under the GDPR in the European Economic Area and the United Kingdom or under the CCPA in California. These can include the right to object to or restrict processing, the right to data portability, and the right to complain to your data protection authority. We do not discriminate against anyone for using these rights. To use any of them, email support@skyyn.app. We reply within 30 days.
Where the GDPR applies, we process your data to perform our contract with you (providing the app), on the basis of your consent (sending photos and messages to AI providers, and notifications), and for our legitimate interests (security, preventing abuse and improving the app). Your data is processed in the United States.
9. Children
Skyyn is not directed at children under 13, and we do not knowingly collect personal information from them. If you believe a child under 13 has given us information, email support@skyyn.app and we will delete it.
10. This website
skyyn.app does not use advertising cookies. If you send a message through the support form, we receive your name, email address and message and use them only to reply. We may measure visits to the site in aggregate with Google Analytics for Firebase. Links to the App Store and Google Play carry campaign labels so that we can tell which page led to an install.
11. Changes to this policy
We will tell you about material changes by email or in the app at least 30 days before they take effect. The date at the top of this page shows when the policy was last changed.
