Open the app and take a clear photo of your stamp, or select an existing image from your photo library. Our AI analyzes the stamp's design, colors, perforations, and other identifying features, then matches it against a comprehensive database. Within seconds, you'll receive the stamp's identification details and an estimated market value based on current collecting trends.

Our AI provides highly accurate identifications for most common and many rare stamps. However, results are informational estimates only and should not be treated as professional appraisals. Stamp values can vary based on condition, centering, gum quality, cancellation type, and current market demand. For high-value stamps, we recommend consulting a certified philatelist or professional grading service for a definitive assessment.

Free users receive a limited number of stamp scans per day. Paid subscribers get unlimited scans with no daily cap. Your remaining daily scans are displayed on the home screen if you are on the free plan. Scan limits reset at midnight in your local time zone.

Stamp Identifier: Check Value offers a free plan with limited daily scans and a paid subscription that unlocks unlimited scans, detailed valuation history, and advanced identification features. Subscriptions are billed through the Apple App Store and renew automatically unless cancelled at least 24 hours before the end of the current period. You can manage or cancel your subscription at any time in Settings > [Your Name] > Subscriptions on your iOS device.

When you scan a stamp, the photo is securely transmitted to our servers for AI analysis. Images are processed solely to identify and value your stamp, then deleted from our processing servers within 24 hours. We do not use your stamp photos for training AI models or share them with third parties. Photos saved to your scan history remain on your device and are under your control.

Open the app and navigate to the subscription or upgrade screen (usually found in Settings or prompted when you try a premium feature). Choose a plan — monthly, annual, or any other available option — then tap Subscribe or Start Free Trial. Confirm your purchase using your Apple ID (iOS) or Google account (Android). If a free trial is available, it will be shown before you confirm. You will not be charged during the trial period, and you can cancel at any time during the trial without being charged. Free trial eligibility is managed by Apple and Google — if you have previously subscribed through the same account, you may not be eligible for another trial.

Subscription management is handled by Apple (iOS) or Google (Android), not by Elemental Ridge directly. On iOS: open Settings, tap your name, then tap Subscriptions. Find the app and select a different plan or cancel. On Android: open the Google Play Store, tap your profile icon, then Payments & subscriptions > Subscriptions. Find the app and tap Change plan or Cancel subscription. Plan changes typically take effect at the start of the next billing cycle.

Cancelling stops future charges. You retain access to premium features until the end of the current billing period. On iOS: Settings > [Your Name] > Subscriptions, tap the app name, then Cancel Subscription. On Android: Google Play Store > Profile > Payments & subscriptions > Subscriptions, tap the app, then Cancel subscription. Important: Deleting the app does NOT cancel your subscription. You must cancel through the App Store or Google Play to stop future charges.

All subscriptions renew automatically unless you cancel before the renewal date. Your account will be charged within 24 hours before the end of the current billing period. The renewal price is the same as your original price unless you have been notified of a price change. You can turn off auto-renewal at any time by cancelling — you will still have access until the end of the period you have already paid for.

When a subscription expires, your access to premium features will be restricted. Your data is not deleted — any content you created while subscribed remains available. You can still use free features. Premium-only features will be locked until you resubscribe. If your subscription lapsed due to a payment failure, you can resubscribe at any time through the App Store or Google Play.

If you reinstall the app or switch to a new device, you can restore your active subscription without paying again. On iOS: open the app, go to the subscription or settings screen, and tap Restore Purchases. Sign in with the same Apple ID if prompted. On Android: make sure you are signed in with the same Google account, reinstall the app, and your subscription should be recognized automatically. If not, look for a Restore Purchases option in settings. Purchases can only be restored to the same Apple ID or Google account used for the original purchase.

Elemental Ridge does not process payments directly. All billing is handled by Apple (for App Store purchases) or Google (for Google Play purchases). Your payment method is stored securely by Apple or Google, not by us. Charges appear on your Apple ID or Google account statement. We do not have access to your full payment details. To update your payment method, do so through your Apple ID settings or Google Play account settings.

Because billing is managed by Apple and Google, all refund requests must go through them directly. For Apple: visit reportaproblem.apple.com, sign in, find the purchase, and select Request a Refund. For Google: visit play.google.com/store/account/subscriptions or the Google Play Help Center. Google's policy allows refunds within 48 hours of purchase for most apps. If you are requesting a refund because of a technical issue, please also contact our support team so we can investigate.

On iOS: open Settings, tap your name, then Media & Purchases > View Account > Purchase History. Apple also sends email receipts for every charge. On Android: open the Google Play Store, tap your profile icon, then Payments & subscriptions > Budget & history > Purchase history. Google also sends email receipts to your Google account address.

If you see an unexpected charge, it is most likely due to: subscription auto-renewal at the start of a new billing period, a free trial ending and the subscription beginning, a family member subscribing using a shared payment method, or a forgotten subscription. Check your purchase history or review active subscriptions in your Apple ID or Google Play account settings. If you still do not recognize the charge, contact our support team with the date and amount.

Subscription prices are set in the local currency for your region as determined by the App Store or Google Play. Prices may vary by country due to regional pricing and tax requirements. Currency conversion is handled by Apple or Google. If you travel or change your account region, pricing may change accordingly. All current pricing is shown on the subscription screen within the app before you confirm a purchase.

You have the right to delete your personal data at any time. Open the app and go to Settings, then look for a Delete Account or Delete My Data option. If you cannot find it, reach out to us via our contact page with the subject line "Data Deletion Request" and include your account identifier. Deleting your data is permanent and cannot be undone. Locally stored content will also be removed when you uninstall the app.

Our apps use a combination of on-device storage (preferences, cached content, locally saved items) and cloud storage (account information, synced data, anonymized analytics). Data stored on your device is not accessible to us unless you explicitly share it. Our apps are designed with a privacy-first approach — we prefer storing data locally wherever possible. See our Privacy Policy for full details.

Check the app's Settings screen for an Export Data or Download My Data option. If no in-app export is available, reach out to us via our contact page with the subject line "Data Export Request." We will respond within 30 days with your data in a portable format (such as JSON or CSV) where technically feasible.

We do not sell your personal data to third parties. Analytics data, if collected, is anonymized and used only to improve our apps. We comply with applicable privacy laws including GDPR (EU), CCPA (California), and similar regulations. You can request access to, correction of, or deletion of your personal data at any time. For full details, review our Privacy Policy. If you have a specific concern, contact us via our contact page and we will respond within 5 business days.

Try these steps in order: (1) Force-close and reopen the app. (2) Restart your device. (3) Check for app updates — an outdated version may have bugs that have been fixed. (4) Check your internet connection if the app requires network access. (5) Free up storage space — apps can behave unexpectedly when storage is nearly full. (6) Reinstall the app (note: locally stored data may be lost). If none of these resolve the issue, contact our support team with a description of the crash, any error messages, your device model, and OS version.

Make sure you have the latest version of the app. Check your subscription status — some features are only available to subscribers. Check app permissions (camera, microphone, notifications, location) in your device Settings. Try signing out and back in if the app has accounts. Try on a different network, as some features require a stable internet connection. If the problem persists, report it as a bug with details about what you expected versus what actually happened.

On iOS: open the App Store, tap your profile icon, scroll to see pending updates, and tap Update next to the app. You can enable automatic updates in Settings > App Store > App Updates. On Android: open the Google Play Store, tap your profile icon, go to Manage apps & device > Updates available, and tap Update. You can enable auto-update from the app's Play Store page via the three-dot menu.

iOS: we support the current iOS version and the two previous major versions (e.g., if the latest is iOS 18, we support iOS 16 and above). iPhone and iPad are both supported where noted. Android: we support Android 8.0 (Oreo) and above, though performance may vary on older devices. Exact requirements are listed on each app's store page. If the app is not available for download, your OS version may not be supported.

If experiencing connectivity issues: (1) Check your internet connection by opening another app or website. (2) Switch between Wi-Fi and mobile data. (3) Disable any VPN or proxy temporarily. (4) Check for server outages by contacting us. (5) Restart your router for Wi-Fi issues. (6) Check firewall or network restrictions on corporate or school networks. If you consistently have issues on one network but not another, the problem is likely with that network.

Reach out to us via our contact page. Please include: the name of the app, your device model (e.g., iPhone 15, Samsung Galaxy S23), your operating system and version, a clear description of the issue including any error messages, and steps to reproduce the problem if applicable. We aim to respond to all support requests within 2 business days.

Reach out to us via our contact page with the subject line "Bug Report." Include: the app name and version (found in Settings or the store listing), your device model and OS version, a description of the bug (what you expected vs. what happened), steps to reproduce if possible, and screenshots or screen recordings if helpful. We read every bug report and use them to improve our apps.

Reach out to us via our contact page with the subject line "Feature Request." Describe the feature you would like to see and explain how it would be useful. We review all feature requests when planning future updates. While we cannot promise every request will be implemented, popular and frequently requested features are given priority. You can also rate our apps and leave reviews on the App Store or Google Play.
