Inkword Flashcards

Privacy Policy

Effective date: July 25, 2026

This Privacy Policy explains how Inkword Flashcards (“Inkword,” “we,” “us”) collects, uses, and shares information when you use our mobile app and this website. It is written in plain language as a starting point — not legal advice.

Information we collect

  • Account data: email address and name when you create or sign in to an account (for example via Google sign-in).
  • Content you submit: photos or text you scan, words and phrases you select, native-language preference, and flashcards or decks you create.
  • Usage and entitlement data: scan counts for the daily free quota, subscription status, and app events needed to run the product.
  • Device information: basic technical data such as device type and app version, used to keep the service reliable.

How we use your information

  • To provide the core product: scan text, detect phrases, generate flashcards, and sync your decks when you are signed in.
  • To enforce the free daily scan quota and Pro entitlements.
  • To process subscriptions and restore purchases.
  • To respond to support requests you send us.
  • To improve reliability and understand how the product is used (for example product analytics).

Third-party processors we use

We use the following services to operate Inkword Flashcards. Each processes data only as needed for its role:

  • Supabase — authentication and database. Processes account data (email, name / auth identity) and your app content (scans, phrases, flashcards, decks) stored for your account.
  • NestJS (our application API) — runs core product logic on our servers. Processes scan text, phrase-detection requests, flashcard generation requests, deck data, and entitlement checks for authenticated users.
  • OpenAI API — language-model inference. Processes recognized scan text and selected phrases to detect multi-word expressions and to generate flashcard explanations in your language. Do not submit content you are not comfortable sending to this processor.
  • RevenueCat — subscription and purchase management. Processes purchase receipts, subscription status, and identifiers needed to update your Pro entitlement.
  • Coolify — hosting/deployment of our backend on a VPS. Processes server traffic and logs related to running the NestJS API (not a separate consumer of your flashcard content beyond hosting the systems that store and process it).

Legal bases and sharing

We share data with the processors above to provide the service you request. We do not sell your personal information. We may disclose information if required by law or to protect the rights, safety, and integrity of Inkword and our users.

Data retention

We keep account and content data while your account is active and as needed to provide the service. You may request deletion of your account and associated content by contacting us. Backup and legal retention windows may apply for a limited time after deletion.

Children

Inkword Flashcards is not directed at children under 13 (or the minimum age required in your country). We do not knowingly collect personal information from children.

Your choices

  • You can use limited free features without a paid subscription.
  • You can sign out or delete your account by contacting support.
  • You can manage or cancel a subscription through your Apple App Store or Google Play account settings.

International transfers

Our processors may store or process data in countries other than yours. Where required, we rely on appropriate safeguards offered by those providers.

Changes

We may update this policy from time to time. The effective date at the top will change when we do. Continued use of the service after an update means you accept the revised policy.
