Word by Word Privacy Policy

Contents

Last updated: 2026-05-25

1. Introduction

Word by Word is a personal vocabulary diary. You save words you encounter, and we help you remember them. We collect the minimum data needed to store and sync your words.

This policy explains what we collect, where it goes, how long we keep it, and what you can do about it.

2. What we collect

We collect:

The words you save. Each entry is a foreign word, your own translation, and any optional context you add, such as a note, where you saw it, or a practice sentence.
An anonymous device identifier. When you first open Word by Word, we generate a random UUID and store it on your device in the iOS Keychain. This identifier is never linked to a person before you sign in.
Your Apple identifier after Sign in with Apple. If you sign in, we receive a stable identifier from Apple (the sub claim) and store only that value. We do not request your name or email.
Minimal operational records. When Word by Word calls our backend, we may keep technical records needed to run the service, prevent abuse, and rate-limit expensive endpoints. Records may include an anonymous device identifier, route name, timing, status, and request outcome.

We do not collect:

Your email address
Your name
Your phone number
Your location
Your contacts
Third-party analytics, advertising identifiers, or product usage tracking for marketing
Custom in-app diagnostics beyond the default iOS crash reporting you opt into at the system level

3. Third-party processors

Word by Word does not use third-party analytics services. Your own translation is the canonical meaning shown in the app.

On-device Apple frameworks. Word by Word may use Apple's on-device frameworks to support local app behavior. This processing happens on your device for the core workflow and does not send your words to Apple servers from Word by Word.

The current processor inventory does not send user submissions to a cross-border AI processor. If our processor inventory changes in a way that introduces a new cross-border transfer or a new processor, we will update this policy and announce it in the app before the new processor is added.

5. How long we keep data

Anonymous device data. Kept until you uninstall Word by Word. Deleting the app deletes the local Keychain entry and all locally-stored words.
Authenticated data. Kept until you delete your account via Settings → Delete account. Once you delete, the data is gone; see section 7.
Operational records. Backend logs and rate-limit records are kept only as technical records needed to operate and protect the service.

We do not keep backups of deleted accounts.

You have the right to:

Access the data we hold about you (Article 15).
Rectify inaccurate data (Article 16).
Erase your data (Article 17, also called the "right to be forgotten").
Restrict processing in certain circumstances (Article 18).
Data portability: receive your data in a structured, machine-readable format (Article 20).
Object to processing (Article 21).

To exercise the right to erasure, use Settings → Delete account in the app. For any other right, email us at hello@wordbyword.se and we will respond within 30 days.

7. Right to deletion

Settings → Delete account permanently removes:

Your user record on our servers
Every word you have saved
All authentication events tied to your account
Backend operational records that can be tied to your account through the attributed device identifier
The local copy on your device

After deletion, if you sign in again with the same Apple ID, you start fresh. Previously deleted words do not return. We do not maintain a backup that could restore them.

8. Dictionary source attribution

Dictionary data is derived from Wiktionary, licensed under CC BY-SA 4.0 and GFDL. Structured data was processed using Kaikki/Wiktextract.

9. Apple sub identifier

When you sign in with Apple, Apple sends us a stable identifier (the sub claim in the identity token). We store only this value as your user identifier.

We do not request your name or email. The Sign in with Apple consent screen reflects this; we ask only for authentication.

10. Children

Word by Word is not directed at children under 13, and we do not knowingly collect data from children. If you believe a child has signed in, contact us and we will delete the account immediately.

11. Contact

For privacy questions, data access requests, or anything else covered by this policy:

hello@wordbyword.se

This mailbox is operated by the Word by Word team (Eniku AB) and is monitored on working days.

12. Updates to this policy

If we make material changes to this policy, we will announce them in the app at the next launch and update the "Last updated" date at the top of this page. Routine, non-material clarifications may be made without an in-app announcement.

13. Effective date

2026-05-25

This is the version of the policy in effect from the date above until we publish an update.
