Privacy Policy

Last updated: April 28, 2026.

SubHub is a personal subscription tracker. This policy explains what information the app processes, why it is used, and the choices you have.

Information We Collect

We collect the information needed to run the app: account details from Firebase Authentication such as email, display name, and sign-in provider, settings you choose, and the subscription records you add or import. Subscription records can include service names, prices, renewal dates, categories, notes, reminder settings, and payment method labels.

Local Device Storage

SubHub stores limited data in local storage and IndexedDB to keep you signed in and remember preferences. Clearing browser or app site data, signing out, or deleting your account removes local app data where applicable. SubHub does not use third-party advertising or analytics cookies.

Payment Method Labels

SubHub is not a payment processor and does not charge cards or bank accounts. Payment method fields are labels you enter. Do not store full card numbers, security codes, bank credentials, or other sensitive financial secrets in notes or labels.

Reminders and Notifications

If enabled, renewal reminder notifications are scheduled on your device. You can change device reminder settings in the app.

Backups

When you choose cloud backup, a JSON snapshot of your subscriptions, payment method labels, and settings is uploaded to Firebase Storage in your user backup folder, and a log row is written in Firestore. Backups are meant for app recovery, not for storing financial secrets.

Security and App Integrity

We use Firebase security rules, authentication, and app integrity tools such as Firebase App Check or reCAPTCHA to help protect backend calls. No app can guarantee perfect security.

How We Use Information

We use your information to provide account access, show subscription totals, estimate renewals and savings, sync your data across devices, process optional backups, send reminders you enable, secure the app, prevent abuse, and maintain the service.

Legal Bases

We process core account and subscription data to provide the service you request. Optional cloud backups run only when you choose that feature. Security, debugging, fraud prevention, and abuse prevention are handled as necessary to keep SubHub reliable and protected.

Sharing

We do not sell your personal information. Data may be processed by service providers needed to operate SubHub: Google Firebase, Vercel hosting/functions, and Apple platform services. We may disclose information if required by law or to protect the app and its users.

International Processing

SubHub relies on Firebase, Vercel, and Apple platform providers that may process data in countries outside your own. Where required, those providers are expected to use contractual and technical safeguards for international transfers.

Your Choices

• You can add, edit, archive, or delete subscriptions in the app.
• You can export a readable JSON copy of your SubHub account data from Settings.
• You can disable device reminder notifications in Settings.
• You can request account deletion from Settings where available.

Retention and Deletion

Data remains until you delete it, delete your account, or it is no longer needed to provide the service. Account deletion removes Firestore documents, files under your Firebase Storage user folder, and your Firebase Authentication user. Provider security, audit, or legal logs may persist for a limited time where required by law or provider retention policy.

Your Rights

Depending on where you live, you may have the right to access, correct, export, restrict, or delete personal data SubHub holds about you, to object to certain processing, and to withdraw consent for optional features. If you are in the European Economic Area, the United Kingdom, or Switzerland, you also have the right to lodge a complaint with your local data protection supervisory authority.

Children

SubHub is intended for people old enough to manage subscriptions and is not directed to children under 16. If you believe a child has created an account, contact us and we will delete the account.

Controller and Contact

SubHub is a hobby project operated by an individual developer based in Austria. The developer is the controller for SubHub personal data and can be reached at hello@subhub.best. Use the same address to request access, export, correction, or deletion of your data.
