Privacy Policy

Last updated: March 5, 2026

Introduction

OptimAItion ("we," "us," or "our") operates the Detecting Log mobile application (the "App"). This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use the App.

By using the App, you agree to the collection and use of information in accordance with this policy. If you do not agree with this policy, please do not use the App.

Information We Collect

Information You Provide

• Account Information: If you create an account, we collect your email address and a password (which is cryptographically hashed and never stored in plain text).
• Hunt Log Data: Dates, times, location coordinates, location labels, detector model, hunt duration, weather conditions, soil type, notes, and detector settings (sensitivity, discrimination, frequency).
• Find Records: Find type, metal type, VDI readings, depth measurements, and keeper status.
• Photos: Images you attach to hunt logs, which are compressed to a maximum of 500 KB before storage.
• Support Requests: If you contact support through the App, we collect your email address (if provided), subject, and message content.
• Preferences: Your chosen units (imperial/metric), time format, detector defaults, theme preference, and privacy settings.

Information Collected Automatically

• Device Identifier: A pseudonymous client identifier generated locally on your device (not linked to hardware identifiers unless you grant tracking permission).
• Platform Information: Whether you are using iOS or Android, and the App version.
• Location Data: GPS coordinates captured with your permission when logging a hunt. We only request foreground ("while in use") location access — we do not track your location in the background.
• Analytics Data (opt-in only): If you enable analytics in Settings, we collect anonymised usage events such as screens viewed, features used, and interaction patterns. Analytics are disabled by default and require your explicit consent.
• Advertising Identifier (iOS): If you grant App Tracking Transparency (ATT) permission on iOS, your device advertising identifier (IDFA) may be shared with our advertising partner to serve personalised ads. If you decline, ads are served in a non-personalised manner.
• Error Reports: If configured, crash and error data (stack traces and diagnostic context) may be sent to our error monitoring service to help us identify and fix bugs. This data does not include your hunt logs or personal content.

Information We Do Not Collect

We do not collect your real name, phone number, physical address, financial information, or payment card details. All payment processing is handled entirely by Apple (App Store) or Google (Play Store) through their respective in-app purchase systems.

We do not access your contacts, calendar, microphone, or any device sensors beyond GPS location (with your permission).

How We Use Your Information

We use the information we collect to:

• Provide and maintain the App's core functionality (logging hunts, storing finds, displaying maps and statistics).
• Synchronise your data across devices when you opt in to cloud sync (premium feature).
• Process CSV data exports that you request.
• Display your hunt locations on maps.
• Serve advertisements to free-tier users.
• Process subscription purchases and manage premium entitlements.
• Send transactional emails (account verification, password resets, data exports) from our branded email domain.
• Respond to support requests you submit through the App.
• Improve the App based on aggregated, anonymised usage patterns (only with your analytics consent).
• Identify and fix bugs and crashes.

We do not sell, rent, or trade your personal information to third parties.

Third-Party Services

The App uses the following third-party services, each of which has its own privacy policy governing their use of your data:

Data Storage and Security

Local Storage

By default, all your hunt data is stored locally on your device using an encrypted SQLite database. Your data remains entirely on your device unless you explicitly enable cloud sync.

Cloud Storage

If you opt in to cloud sync (available to premium subscribers), your data is stored on servers operated by Supabase (hosted in the United States). Photos are stored in cloud object storage with access-controlled signed URLs that expire after one hour.

Security Measures

We implement reasonable technical and organisational measures to protect your data, including:

• Cryptographic password hashing (never stored in plain text).
• Row-level security policies ensuring users can only access their own data.
• Signed, time-limited URLs for photo access.
• HTTPS/TLS encryption for all data in transit.
• Soft-delete architecture to prevent accidental permanent data loss.

While we strive to protect your information, no method of electronic storage or transmission over the internet is 100% secure. We cannot guarantee absolute security.

Data Retention

• Account Data: Retained until you delete your account.
• Hunt Logs, Finds, and Photos: Retained until you delete them individually or delete your account.
• Local Data: Remains on your device until you uninstall the App or clear App data.
• Analytics Data: Retained by Mixpanel according to their data retention policies (typically up to 180 days).
• Error Reports: Retained by Sentry according to their data retention policies (typically up to 90 days).
• Subscription Records: Retained by RevenueCat for the duration of your subscription relationship plus any legally required retention period.

When you delete your account through the App, we permanently delete all associated cloud data including hunts, finds, photos, settings, exports, subscriptions, and your user profile.

Your Rights and Choices

Data Access and Export

You can export all your hunt and find data at any time using the CSV export feature in the App's Settings.

Data Deletion

You can delete your account and all associated cloud data through Settings → Account → Delete Account. You can also delete only your cloud backup while keeping your account through Settings → Storage & Export.

Analytics Opt-Out

Analytics tracking is disabled by default. You can enable or disable it at any time through Settings → Privacy.

Ad Personalisation

On iOS, you can control ad personalisation through the App Tracking Transparency prompt or your device's Settings. Declining personalisation does not remove ads for free-tier users — it only means ads will be generic rather than targeted. Premium subscribers do not see ads.

Location Permission

You can revoke location permission at any time through your device's Settings. The App will continue to function, but you will not be able to set GPS pins for new hunts.

Additional Rights (EEA/UK/California Residents)

If you reside in the European Economic Area, United Kingdom, or California, you may have additional rights under the GDPR, UK GDPR, or CCPA respectively, including the right to: access the personal data we hold about you; request correction of inaccurate data; request deletion of your data; object to or restrict certain processing; data portability; and lodge a complaint with a supervisory authority.

To exercise any of these rights, contact us at the address below.

California Residents: We do not sell your personal information as defined under the CCPA. We do not have actual knowledge that we sell the personal information of consumers under 16 years of age.

Children's Privacy

The App is not directed at children under the age of 13 (or under 16 in the EEA/UK). We do not knowingly collect personal information from children under these ages. If you are a parent or guardian and believe your child has provided us with personal information, please contact us and we will take steps to delete such information.

International Data Transfers

If you are located outside the United States, please be aware that your data may be transferred to, stored, and processed in the United States where our service providers' servers are located. By using the App, you consent to this transfer. We rely on our service providers' compliance with applicable data protection frameworks for international transfers.

Changes to This Privacy Policy

We may update this Privacy Policy from time to time. We will notify you of material changes by updating the "Last updated" date at the top of this page. We encourage you to review this policy periodically. Your continued use of the App after changes are posted constitutes your acceptance of the revised policy.
