ClearBase · Last updated: April 2026

Who We Are

ClearBase is a mobile application developed and published by CosmoLabs Ltd, a company registered in Scotland, United Kingdom (Company No. SC883326). Our website is cosmolabs.co.uk. We are registered with the UK Information Commissioner's Office (ICO No. ZC111592).

Data We Collect

ClearBase collects the following data to provide its core functionality:

• Location data — your device's GPS position, used to display tides for your nearest station, show local SAR assets, and (if crew sharing is active) share your position with your group. Location is only accessed while the app is in use.
• Crew session data — if you create or join a crew location sharing group, your position and display name are transmitted to our server for the duration of the active session only. No crew location data is stored after a session ends.
• Account data — if you create an account (required for crew features), we store your email address and a hashed password.
• Subscription data — if you subscribe, payment status is verified via RevenueCat. We do not store card details.
• App settings — your preferences (alert radius, saved stations, notification settings) are stored locally on your device and optionally synced to your account if signed in.
• Crash and diagnostic data — anonymised crash reports to help us identify and fix issues. No personally identifiable information is included.

Data We Do NOT Collect

• We do not collect background location data without explicit consent
• We do not sell data to advertisers or third parties
• We do not use behavioural tracking or advertising SDKs
• We do not store historical crew location trails
• We do not access your contacts, photos, or files

Third-Party Services

ClearBase integrates with the following third-party data providers:

• Met Office API — weather data. Only your device's coordinates are transmitted, never personal details.
• UK Hydrographic Office / Admiralty — tidal data. Coordinates only.
• OpenSky Network — SAR aircraft positions. Read-only public feed.
• what3words — location-to-words conversion. Coordinates and words are transmitted to what3words' API. See what3words Privacy Policy.
• RevenueCat — subscription management. Handles payment verification. See RevenueCat Privacy Policy.

Location Data

ClearBase requires location access to function. Location is used to:

• Show your nearest tidal station and weather observation point
• Display nearby SAR assets on the map
• Share your position with a crew group (only when actively in a session)
• Provide what3words addresses for your current position

You can revoke location permissions at any time in your device settings. Core features requiring location will not function without it.

Crew Location Sharing

Crew location data is transmitted over an encrypted connection and held in temporary session storage only. When a crew session ends (manually or by timeout), all participant location data is deleted from our servers. No historical position trails are retained. Your display name within a session is visible to all group members.

Push Notifications

ClearBase sends push notifications for SAR launch alerts and subscription reminders. You can manage notification preferences within the app or in your device settings. Notification tokens are stored securely and used only to deliver alerts to your device.

Data Retention

• Crew location data: deleted immediately on session end
• Account data: retained while your account is active. Deletable on request.
• Crash reports: retained for 90 days, then automatically deleted

Your Rights Under UK GDPR

You have the right to access, correct, or delete your personal data. To exercise these rights, contact us at support@cosmolabs.co.uk. You can also lodge a complaint with the UK Information Commissioner's Office at ico.org.uk.

Children's Privacy

ClearBase is intended for professional and adult use. It is not directed at children under 13 and we do not knowingly collect data from children.
