Privacy Policy

Last updated: August 18, 2026

Elma Digital Ltd ("Elma Digital," "we," "us," or "our") built and operates Timestamp — Photo Date Stamp (the "App"), and this website. This Privacy Policy explains what information the App and this website collect, how it's used, and who it's shared with.

The short version

Your photos are stamped entirely on your device and never leave it. Timestamp doesn't require an account, doesn't operate a backend server that stores your photos, and doesn't use Apple's App Tracking Transparency framework to track you across other apps or websites. The sections below cover the specifics.

Information We Collect

Photos and camera

To stamp a photo, the App asks for permission to access your camera and photo library, using these exact system prompts:

• Camera: "Photo Date Stamp needs access to your camera to take photos and add date stamps."
• Photo Library: "Photo Date Stamp needs access to your photo library to select photos for stamping and to save stamped photos."
• Save to Photo Library: "Photo Date Stamp needs permission to save stamped photos to your library."

All date-stamping happens locally on your device using iOS's on-device image rendering. Stamped photos are saved as new copies to your photo library — your originals are never modified. Elma Digital does not receive, upload, or store copies of your photos on any server.

Account information

Timestamp does not require you to create an account, sign in, or provide your name, email address, or any other personal registration information to use the App.

Subscription and purchase information

Timestamp offers optional auto-renewable subscriptions (weekly and yearly). Purchases are processed entirely by Apple through your Apple ID — Elma Digital never sees or stores your payment card details. To manage active subscriptions and unlock premium features, the App uses RevenueCat, a third-party subscription management service, which receives an anonymous, app-generated identifier along with purchase and subscription-status metadata (such as which product was purchased and when it renews). RevenueCat's own privacy practices are described at revenuecat.com/privacy.

Advertising

The free version of Timestamp shows optional rewarded ads (to unlock extra stamped photos or themes) and, occasionally, interstitial ads, served through Google AdMob (part of Google's Mobile Ads SDK). Serving these ads may involve Google collecting technical and device information — such as device type, operating system version, and general (non-precise) location — under Google's own privacy practices, described at policies.google.com/privacy. Premium subscribers do not see any ads.

Timestamp does not present Apple's App Tracking Transparency (ATT) prompt and does not access your device's advertising identifier (IDFA) to track you across other companies' apps or websites.

"Our Apps" feature

The App's "Our Apps" screen fetches a public list of Elma Digital's other App Store listings using Apple's public iTunes Lookup API. This is a simple public catalogue request — no information about you or your device is included in it.

Diagnostic and usage data

Like all apps distributed through the App Store, Timestamp may generate standard crash and performance diagnostics that Apple makes available to developers through App Store Connect. This aggregated data is not linked to your identity by us and is used only to catch and fix bugs.

How We Use Information

• To provide the App's core stamping, theming, and batch-processing features
• To manage and verify your subscription entitlements (via RevenueCat and Apple)
• To display ads to free-tier users (via Google AdMob) and unlock rewards when you choose to watch one
• To diagnose crashes and improve app stability

Who We Share Information With

We don't sell your information. The only parties information passes through are the service providers described above, each acting under their own privacy policy:

• Apple Inc. — App Store distribution, payments, and platform-level diagnostics
• RevenueCat, Inc. — subscription and entitlement management
• Google LLC (AdMob) — ad serving for free-tier users

Data Retention

Because photos are processed and stored only on your device, Elma Digital does not retain copies of your photos at all. Subscription and entitlement records are retained by RevenueCat and Apple according to their own retention practices, for as long as needed to manage your subscription and resolve support or billing questions.

Your Choices

• Camera and Photo Library access can be granted, denied, or revoked anytime in iOS Settings → Privacy & Security.
• Subscriptions can be reviewed, changed, or canceled anytime in iOS Settings → [your name] → Subscriptions.
• Ad personalization can be limited in iOS Settings → Privacy & Security → Apple Advertising and through Google's own ad settings at adssettings.google.com.

Children's Privacy

Timestamp is not directed at children under 13, and we do not knowingly collect personal information from children. If you believe a child has provided us with personal information, contact us using the details below and we'll address it.

International Users

Because Timestamp relies on Apple, RevenueCat, and Google as described above, information may be processed in countries other than the one you're using the App in, subject to each provider's own safeguards.

Changes to This Policy

If this Privacy Policy changes, we'll update it here and revise the "Last updated" date at the top of this page.
