Privacy Policy

1. Information We Access

1.1 App Data (Stored Locally)

Your mood entries, habit logs, context tags and booster history are stored entirely on your device. This data never leaves your device, is never uploaded to our servers, and is never shared with third parties.

1.2 App Settings (Stored Locally)

Your preferences including selected habits, onboarding responses and app settings are stored only on your device and never leave it.

1.3 Apple Health (Read on Your Device)

If you choose to connect Apple Health, MoodMark reads your daily step count to show whether walking more lifts your mood. Step data is read on your device only. It is never sent to our servers, never shared with third parties, and never used for advertising, marketing or analytics. You can turn this off at any time in the Settings app under Health > Data Access & Devices.

2. Information We Do Not Collect

• Name, email or contact information, unless you choose to email us (see 3.4)
• Precise location or GPS data
• Contacts, calendar or photos
• Health data from Apple HealthKit — your step count is read on your device and never collected
• The content of your mood entries, habit logs or journal — these never leave your device

3. Third-Party Services

3.1 RevenueCat

We use RevenueCat to manage subscriptions and process payments. RevenueCat may collect:

• Subscription status and purchase history
• Device type and OS version
• Anonymised purchase analytics
• Your device's advertising identifier (IDFA) and vendor identifier (IDFV), which RevenueCat passes to Tenjin so subscription revenue can be matched to advertising campaigns

3.2 Apple Services

We integrate with Apple StoreKit for payment processing, which operates under Apple's Privacy Policy.

3.3 Advertising Measurement (Tenjin)

We advertise MoodMark on platforms such as TikTok. To understand which ads bring people to the app, we use Tenjin, an attribution service. If you allow tracking when asked, Tenjin receives:

• Your device's advertising identifier (IDFA) and vendor identifier (IDFV)
• Your IP address, used to determine your country
• App events such as opening the app, completing onboarding, logging your first mood, and starting a subscription — event names only, never their content

Tenjin shares this with TikTok solely to measure ad performance. Your mood entries, habit logs and journal are never included.

We also use Apple's SKAdNetwork, which measures installs privately without identifying you.

3.4 Email Feedback

If you email us, for example from Send feedback in the app, we receive your email address, your message and the app and iOS version included at the bottom. We use them only to read and reply to your feedback, and you can ask us to delete them at any time.

3.5 App Analytics (PostHog)

We use PostHog to understand how people move through the app, for example how many finish onboarding. PostHog receives:

• A random ID created by the app, which is not linked to your name, email or advertising identifier
• Which screens you view and when, such as each onboarding step and finishing onboarding
• Device model, iOS version, app version, language and time zone
• Your IP address, which may be used to estimate your country

4. Data Storage

All mood and habit data is stored locally on your device. There is no account creation required and no cloud sync. Uninstalling the app removes all your data permanently.

5. Data Deletion

Uninstalling MoodMark removes all app data from your device instantly. There is no account to delete. To stop the advertising measurement described in section 3.3, turn off tracking in iOS Settings → Privacy & Security → Tracking.

6. Children's Privacy

MoodMark is not directed at children under the age of 13. We do not knowingly collect personal information from children.

7. Your Rights

All Users

EU Users (GDPR)

• Rights to access, rectification, erasure and portability apply

California Users (CCPA/CPRA)

• Right to know and delete applies via the app controls described above
