Privacy Policy

The Short Version

Your personal content — check-ins, journal entries, medications, mood — stays on your device. We never transmit, store, or have access to it.

We do collect anonymous usage analytics, crash reports, and (optionally) session interaction patterns to make the app more reliable. You can opt out of analytics in Settings. Details below.

Health Disclaimer

Altitude is a support tool for ADHD coping, not medical advice. It does not diagnose conditions, prescribe treatment, or replace professional care. Consult your healthcare provider for diagnosis or treatment decisions, including any questions about medication.

Information We Collect

Personal Data You Create — Stays On Your Device

All content you create stays on your device using local MMKV storage. We have no servers that hold this data and no way to access it. This includes:

• Check-in history, mood, and emotional weather selections
• Journal entries and notes
• Medication schedules, names, and reminder times
• Daily anchors and routines
• Quick wins, body checklists, session history
• Notification preferences and wake time

When you uninstall the app, this data is deleted with it.

Anonymous Usage Analytics — PostHog

We use PostHog to understand which features people use, so we can fix bugs and improve. PostHog receives:

• Anonymous user identifier (a random ID generated on your device — never tied to your name, email, phone, or Apple ID)
• Screen views and feature interactions (which buttons you tap, which screens you visit)
• Device type and operating system version
• Coarse location derived from IP address (country / region only)

PostHog does not receive your name, email, journal contents, medication names, mood entries, or any health-related data. Analytics are processed in the European Union (PostHog EU region).

You can opt out of analytics at any time: Settings → Privacy → toggle Analytics off.

Crash & Performance Reporting — Sentry

When the app crashes or hits an unexpected error, we use Sentry to capture diagnostic data so we can fix it. Sentry receives:

• Crash logs and stack traces
• App version, device model, operating system version
• Recent navigation breadcrumbs (which screens you were on before the error)
• Performance traces (how long screens take to load)

Sentry does not receive your name, email, journal contents, medication entries, or other content you've created. We disable Sentry's default PII collection. Crash data is processed in Germany (Sentry EU/DE region).

User Feedback — Sentry Feedback

If you tap Settings → Send feedback, your typed message is sent through Sentry's feedback channel so we can read and respond. The form collects the free-text message you write, and — at your option — a screenshot you choose to attach and an email address you choose to provide so we can follow up. Both the screenshot and the email field are optional; leave them blank if you'd rather stay anonymous. Don't include personal information in the message itself if you'd prefer not to share it.

Session Interaction Patterns — Microsoft Clarity

We use Microsoft Clarity to understand how people interact with the app — where they tap, which flows feel slow, where they get stuck. Clarity receives:

• Anonymous interaction telemetry (taps, scrolls, screen visits — patterns only)
• Device type, screen size, operating system version
• Coarse location derived from IP address

Per Microsoft's documentation, the Clarity mobile SDK does not capture screenshots or screen recordings, and personal information detected on screen is automatically masked. Clarity data is processed by Microsoft on Azure cloud infrastructure.

Clarity is currently used only with internal-tester (closed-beta) builds. We will add an explicit consent prompt before enabling Clarity for general public users.

Email Newsletter & Beta Invites — Kit

If you sign up via the form on altitude-adhd.app/beta (or the equivalent section on the home page), your email address is sent to Kit so we can email you a beta invite and occasional update messages. Kit receives:

• The email address you submit
• A confirmation timestamp (when you click the double opt-in link in Kit's confirmation email)
• The page URL that referred you to the signup form

We use Kit's double opt-in flow: your address is not added to the active list until you confirm it from the email Kit sends you. Every email Kit sends includes an unsubscribe link. You can also email [email protected] at any time to be removed.

This is the only place we store personal information on a remote server — and only if you explicitly sign up. The app itself never sends your email address anywhere.

How We Use This Information

• Understand which features actually help people, and which don't
• Find and fix bugs and crashes
• Improve performance and reliability
• Respond to feedback you send through the in-app form

We do not sell, rent, or share data with advertisers, brokers, or any third party for marketing purposes. We do not use any tracking SDKs that follow you across other apps or websites.

No Other Third Parties

Altitude does not use:

Data Security

All your personal content (check-ins, journal, medications, anchors) is stored locally on your device using MMKV storage. Your device's built-in security (passcode, Face ID, Touch ID) protects this data.

Analytics, crash reports, and feedback are transmitted over HTTPS to PostHog (EU), Sentry (Germany), and Microsoft Clarity (Microsoft Azure). We don't operate any servers that store your personal content.

Your Privacy Controls

• Opt out of analytics: Settings → Privacy → Analytics toggle. Stops sending data to PostHog.
• Delete all your data: Settings → Clear All Data. Wipes everything stored on the device.
• Uninstall: Removes all local content and stops all data collection.
• Notifications: Notifications default OFF. You decide which categories (morning, hyperfocus body checks, creative session nudges) to enable in Settings → Notifications.

Data Retention and Deletion

Your personal content stays on your device until you delete it (Settings → Clear All Data) or uninstall the app. We don't have a copy.

Analytics, crash, and interaction data sent to PostHog, Sentry, and Microsoft Clarity is retained according to each provider's policies — typically 30–90 days for raw events, longer for aggregated stats. None of it is tied to your name or email.

Children's Privacy

Altitude is not directed to children under 13. We do not knowingly collect information from children.

If you believe a child has used Altitude, please contact us at [email protected].

International Users

Your personal content stays on your device, regardless of where you are.

Analytics, crash reports, and interaction data are transmitted to:

• PostHog (European Union region)
• Sentry (Germany — DE region)
• Microsoft Clarity (Microsoft Azure cloud, multi-region)

Each provider operates under their own GDPR / CCPA frameworks. None of this data identifies you personally.

Changes to This Policy

We may update this privacy policy as the app evolves. Changes will be posted on this page with an updated effective date. Material changes will also be communicated in-app.

Continued use of Altitude after changes means you accept the updated policy.
