Privacy Policy

Who we are

SkinStory ("we", "us", "our") is a mobile application that helps you track and understand your skin through daily photos and lifestyle logging. Our contact email is hello@skinstoryapp.com.

What data we collect

SkinStory collects only the information you choose to provide:

• Profile information — your nickname, email address, gender, age, and weight (used solely to calculate your personalised daily water intake goal)
• Daily photos — skin photos you take within the app, stored locally on your device
• Daily diary entries — diet logs, allergen tracking, product notes, water intake, and how you're feeling
• Cycle data — menstrual cycle information if you choose to log it, used only to surface patterns in your own diary
• Skincare products — names of products you're currently using, stored in your profile

Where your data is stored

By default, all your data is stored locally on your device. Your photos, notes, and diary entries never leave your phone unless you explicitly enable account sync.

If you create a SkinStory account and enable optional cloud backup, your data is synced to Firebase (Google's secure cloud infrastructure) so you can restore your history if you change devices. Firebase data is encrypted in transit and at rest.

You can delete your cloud data at any time from the app's settings screen.

How we use your data

Your data is used only to power SkinStory's features:

• Display your photo timeline and diary history
• Generate AI-powered skin summaries from your own photos
• Surface patterns between your lifestyle choices and skin changes
• Calculate your personalised daily water intake goal

We do not use your data for advertising, profiling, or any purpose beyond the features you see in the app.

What we never do

• ❌ We never sell your data to any third party
• ❌ We never show you advertisements
• ❌ We never share your photos or diary with anyone without your explicit consent
• ❌ We never use your data to train AI models without your opt-in
• ❌ We never track you across other apps or websites

Third-party services

SkinStory uses the following third-party services, solely to operate the app:

• Firebase (Google) — optional cloud backup and account sync. Firebase's privacy policy applies to data you choose to sync: firebase.google.com/support/privacy

We do not use any advertising SDKs, analytics platforms that track individual users, or social media trackers.

Your rights (GDPR)

If you are located in the European Economic Area (EEA) or UK, you have the following rights regarding your personal data:

• Access — You can request a copy of all personal data we hold about you
• Erasure — You can request deletion of your account and all associated data at any time, both locally and from our servers
• Portability — You can request an export of your data in a machine-readable format (JSON)
• Rectification — You can correct any inaccurate information in your profile at any time within the app
• Restriction — You can request that we restrict processing of your data in certain circumstances
• Objection — You can object to our processing of your data where we rely on legitimate interests

To exercise any of these rights, email us at hello@skinstoryapp.com. We will respond within 30 days.

Data retention

Local data is retained on your device until you delete it or uninstall the app. If you use cloud sync, your data is retained on Firebase until you delete your account. When you delete your account, all cloud data is permanently erased within 30 days.

Children's privacy

SkinStory is intended for users aged 13 and older. We do not knowingly collect personal information from children under 13. If you believe a child under 13 has provided us with personal data, please contact us and we will delete it promptly.

Security

We take the security of your personal data seriously. Local data is protected by your device's built-in security features. Cloud-synced data is encrypted in transit (TLS) and at rest (AES-256) on Firebase. We regularly review our security practices.

Changes to this policy

If we make significant changes to this privacy policy, we will notify you through the app before the changes take effect. The "last updated" date at the top of this page will always reflect when changes were last made.
