ProofStamp Privacy Policy

Overview

Adstar Labs is the developer brand responsible for ProofStamp. This Privacy Policy explains how the ProofStamp mobile application handles information.

ProofStamp is a focused productivity & photo utilities app. Its core purpose is to take a photo inside the app and add a short job, site, delivery, or task note. It does not require an account, does not contain advertising, does not sell personal information, and does not track you across apps or websites.

Information you provide

Depending on how you use ProofStamp, you may enter or create:

• Recent proof-log records containing capture time, note, and optional coordinates
• The user's add-location preference
• Captured images in the app's temporary cache until the operating system clears them
• Stamped photo-library copies created only when the user chooses Save
• Selected app language and analytics/diagnostics consent choice

This content, together with your language and privacy choices, is stored in the app’s local storage on your device. Adstar Labs does not operate an account or cloud-sync service for ProofStamp and does not receive this content through the app.

Device access and user-directed exports

ProofStamp may request the following device access only when needed for a feature you choose:

• Camera access, requested to take a proof photo
• Foreground precise/coarse location, requested only when the user enables the location switch
• Photo-library add access, requested only when the user saves a stamped image

Permission-dependent processing is performed for the requested feature. Denying a permission may limit that feature but does not create an account or send your app content to Adstar Labs.

ProofStamp includes one or more user-directed export, backup, save, or share controls. The destination you choose may process the exported content under its own privacy terms. Adstar Labs does not receive that content merely because you use the share or export control.

Analytics and diagnostics

Analytics and crash reporting are off by default. They are enabled only after you make a choice in the app’s Privacy screen. If enabled, Google Firebase may process the following limited information:

ProofStamp telemetry is designed not to include the content you enter or create in the app. The app does not use advertising identifiers, does not set a custom Firebase user ID, and has no account identity to associate with analytics or crash data.

How we use information

If you enable analytics or diagnostics, we use the resulting information to measure whether core features work, understand general feature use, prioritize improvements, diagnose crashes, and protect app integrity. We do not use it for advertising, employment, insurance, credit, or other eligibility decisions.

Sharing and service providers

We do not sell personal information. When you enable analytics or diagnostics, Google Firebase processes limited information on our behalf as a service provider. Google’s handling of this information is also governed by its Firebase Privacy and Security documentation.

We may disclose information if required by law, to respond to valid legal process, or to protect users, the public, our rights, or the security of our services.

Retention and deletion

Local app data

Local content remains in app storage until you delete entries, clear the app’s data through device settings, or uninstall ProofStamp. User-directed exports or system backups are controlled separately by you and the destination or backup provider.

Analytics and diagnostic data

Firebase retains analytics and diagnostic information according to the service configuration and Google’s retention practices. Crashlytics crash reports are generally retained for 90 days. Because ProofStamp has no account system, we generally cannot connect Firebase-generated identifiers to your name.

Children’s privacy

ProofStamp is not directed to children under 13 or the minimum age required by local law. We do not knowingly collect personal information from children. If you believe a child has provided information to us, contact us so we can review the matter.

Security

We use reasonable technical and organizational safeguards appropriate to the limited information we process. Firebase data is transmitted using encrypted connections. No method of electronic storage or transmission is completely secure.

Your choices

• Analytics and diagnostics: use the Privacy screen inside ProofStamp to enable or disable collection at any time.
• Local data: use available delete controls, clear app data in device settings, or uninstall the app.
• Device permissions: manage permissions through your operating-system settings.
• System backup: manage app backup behavior through operating-system or backup-provider settings.
• Privacy rights: depending on where you live, you may have rights to request access, correction, deletion, restriction, or objection regarding information we process.

International processing

Google Firebase may process information in countries other than the country where you live. Where required, service providers use recognized safeguards for international data transfers.

Changes to this policy

We may update this Privacy Policy when ProofStamp changes or when legal requirements change. The “Last updated” date above identifies the latest revision.
