Privacy Policy

Last updated: March 2026

Overview

Deckify ("we", "us", or "our") is committed to protecting your privacy. This Privacy Policy explains what information we collect when you use the Deckify iOS app, how we use it, and how we keep it safe.

Information We Collect

• Account data – your email address and display name. • Study data – flashcard decks, cards, review logs, and session results, stored to enable cross-device sync. • Usage data – aggregate, anonymised analytics. No personally identifiable information is included. • Device data – we do not collect device identifiers, location data, or contacts.

How We Use Your Information

Your information is used solely to: • Provide and improve the Deckify service. • Sync your data across your devices. • Send optional study reminder notifications (only when you opt in). We do not sell, rent, or share your personal data with third parties for marketing purposes.

Data Storage & Security

Your data is stored using Supabase, a GDPR-compliant backend provider. All data is encrypted in transit (TLS) and at rest (AES-256).

Data Retention & Deletion

Your data is kept for as long as your account is active. You can permanently delete all your data at any time from Settings → Data → Delete All Data. You may also request full account deletion, which removes your authentication record and all associated data from our systems.

Email Communications

We use Resend (resend.com) as our transactional email provider. Your email address is shared with Resend solely to deliver account-related messages such as email verification and password reset links. We do not use your email address for marketing or newsletters without your explicit consent. Resend is contractually bound to process your data only on our behalf.

Push Notifications

Push notifications are entirely opt-in. You can disable them at any time from Settings → Notifications or via your device's system settings.

AI Features

Deckify may introduce AI-assisted features in the future. If and when these are added, this Privacy Policy will be updated to describe how any related data is processed before those features go live.

Data Processors

We rely on the following sub-processors to operate Deckify. Each is bound by a Data Processing Agreement and processes your data only as instructed by us: • Supabase (supabase.com) – database, authentication, and file storage. Data is stored in EU data centres (eu-west-1, Ireland). • Resend (resend.com) – transactional email delivery. • Apple Inc. (apple.com) – app distribution via the App Store and, where applicable, Sign in with Apple. We do not engage any other sub-processors that have access to your personal data.

Children's Privacy
