Privacy Policy

CloudEx Inc. ("we", "us") operates the app "Subscription Watch" (the "Service"). This Privacy Policy explains what information we collect, how we use it, and the choices you have. By using the Service, you agree to the practices described in this policy.

1. Our approach

Subscription Watch lists the subscriptions (recurring payments) you pay every month or year and reminds you before each payment and before a free trial ends. Adding subscriptions, totals, the calendar, reminders and payment history all work entirely on your device. There is no account, and the App never connects to your bank, credit cards or the accounts of the services you track. What you enter is stored on your device, and we never view, collect, upload or send it to our servers. Specifically, we have no access to any of the following:

  • The names, amounts, currencies, payment dates, payment methods and categories of the subscriptions you add
  • Payment history, price changes, and cancellation or pause records
  • Cancellation notes, management-page URLs, notes of the email address or ID you use to sign in, and other notes
  • Settings such as a monthly limit or the number of people you split a cost with

What you enter leaves your device only through actions you take yourself: exporting a backup or CSV, opening a management page, or searching how to cancel (Section 3.2).

2. Reminders and app lock

  • Reminders: Reminders before a payment, before a free trial ends, before a contract ends and so on are created and shown on your device using the device's alarms. Their content never passes through our servers or any third party's.
  • App lock: Locking with fingerprint, face or PIN uses Android's standard biometric system. Authentication is done by the operating system; neither the App nor we ever receive fingerprint or face data.
  • Widgets and Quick Settings tile: Home-screen widgets and the Quick Settings tile show amounts such as your next payment and totals. If you do not want others to see them, use "Hide amounts on Home and widgets" in Settings.

3. Information we collect

3.1 Information collected automatically

  • Anonymous crash reports: We use Firebase Crashlytics. When the App crashes, it collects the stack trace, device model, OS version and app version. Reports contain neither the subscriptions you entered nor information that identifies you. Each report also includes a random identifier created for each installation of the App; it is not linked to your name or Google account.
  • Purchase information: To confirm the one-time "Premium" purchase, we use the purchase token issued by Google Play. We never receive payment details such as credit card numbers.
  • List of our other apps: To introduce our other apps, the App downloads their names, descriptions and icons from our content server (static files on Cloudflare Pages). These requests contain no personal data from the App. As with any web request, the server receives your device's IP address. Tapping an app in the list opens its page on Google Play.

The App does not use usage analytics tools or the advertising ID.

3.2 Information that leaves your device when you act

  • Importing exchange rates (Premium): Only when you press "Update rates automatically", the App downloads the list of European Central Bank reference rates from Frankfurter (api.frankfurter.dev), or from the European Central Bank (www.ecb.europa.eu) if that fails. These requests include neither your subscriptions nor the currencies you use. As with any web request, the server receives your device's IP address.
  • Opening a management page / searching how to cancel: The management-page button opens the URL you saved (or the Google Play / App Store subscription management page) in your browser. "Search how to cancel" opens a Google search for a query that contains the service's name. Those sites handle information under their own privacy policies.
  • Backups and CSV: When you export a backup or CSV, everything you entered is saved as a file in the location you choose (a folder on your device, a cloud storage app, and so on). If you turn on automatic backup, the App writes a backup to the folder you chose once a day. You are responsible for the exported files, and we never receive their content.
  • Viewing this Privacy Policy: Opening this policy in the App loads this page (subscriptionwatch.cloud-ex.biz).

3.3 Information stored only on your device

  • Subscription data: Your subscriptions, categories, payment methods, payment history, price changes, exchange rates and the contents of the trash are stored in the App's private storage on your device. Subscriptions in the trash are deleted automatically after 30 days.
  • Copies kept before a restore: When you restore from a backup, the App keeps a copy of your data at that moment on the device so you can undo the restore (up to the 3 most recent).
  • App settings: Settings such as currency, display, reminder days and time, and lock settings are stored on your device.
  • Android backup: If backup is turned on in your device settings, Android may include your subscription data and settings in a backup to your own Google account (so your data is not lost when you change phones). This is done by Android, and we cannot access its content.
  • When you uninstall: Uninstalling the App or clearing its data deletes the subscription data and settings on your device. Backup and CSV files you exported remain until you delete them.

3.4 Information we do not collect

  • The subscriptions, payment history and notes you enter (see Section 1)
  • Bank account, credit card or service account information (the App does not connect to any of these)
  • Your name, email address, phone number or contacts (the App has no account sign-up)
  • Location, photos, or camera or microphone data
  • Your browsing history or the content of other apps

3.5 Permissions the App requests and why

  • Notifications (POST_NOTIFICATIONS, Android 13 and later) — Used to show reminders before a payment, before a free trial ends and before a contract ends, and the monthly summary. If you do not allow it, every other feature, such as the list and totals, still works.
  • Run at startup (RECEIVE_BOOT_COMPLETED) — Used after a restart or an app update to reschedule reminders and to record payment dates that have passed.
  • Biometrics (USE_BIOMETRIC / USE_FINGERPRINT) — Used only when you turn on app lock, to unlock with fingerprint or face.
  • Google Play billing (com.android.vending.BILLING) — Used to buy and restore the one-time Premium purchase.
  • Internet (INTERNET / ACCESS_NETWORK_STATE) — Used only for anonymous crash reports, confirming purchases on Google Play, in-app review and in-app update, downloading the list of our other apps, importing exchange rates (Premium, only when you act), and showing this Privacy Policy in the App. Adding subscriptions, totals and reminders do not need an internet connection.

4. How we use information

We use the limited information we collect only to:

  • Operate and maintain the Service
  • Confirm Premium purchases
  • Diagnose and fix crashes
  • Respond to support requests
  • Comply with applicable law

5. Third-party services

Subscription Watch uses the following third-party services, each with its own privacy policy:

  • Firebase Crashlytics (Google LLC) — anonymous crash diagnostics
  • Google Play Billing (Google LLC) — the one-time Premium purchase. Payment is completed on Google Play; we receive only the purchase token
  • Google Play In-App Review / In-App Updates (Google LLC) — rating and updating without leaving the App, handled by Google Play
  • Cloudflare Pages (Cloudflare, Inc.) — delivery of the list of our other apps (static files)
  • Frankfurter / European Central Bank — delivery of reference exchange rates (Premium, only when you act)

Subscription Watch contains no third-party ad networks and does not share your data with third parties for advertising. The App may show introductions to our other apps.

6. Data retention

  • Crash reports: kept for 90 days, then deleted.
  • Subscription data and settings on your device: kept until you delete them, uninstall the App or clear its data. The trash is emptied automatically after 30 days.

7. International data transfers

We are based in Japan. The infrastructure used for crash diagnostics, delivering the list of our other apps and delivering exchange rates may be located in various countries. When you use the Service, the minimal information described above may be processed outside your country of residence under standard contractual safeguards.

8. Your rights

Depending on where you live (the EEA, the UK, California, Japan and elsewhere), you may have the right to request access to, correction of, or deletion of the limited information we hold. You can:

  • Delete subscriptions and payment records in the App at any time, and delete all data and settings on your device by uninstalling the App or clearing its data
  • Revoke the notification permission at any time in your device settings
  • Contact us at the address below with any request about information we hold

9. Children's privacy

Subscription Watch is not directed to children under 13 (or the minimum age that applies where you live). If we learn that we have collected information from such a child by mistake, we will delete it promptly after being contacted.

10. Changes to this policy

We may update this Privacy Policy from time to time. The latest version is always published at this URL with its effective date. We will also notify you in the App of significant changes where appropriate.
