GlossaSub Privacy Policy

Last updated: 14 November 2026

GlossaSub reads subtitles in games, translates them and can optionally voice them. We care about your privacy and keep the data we collect to a minimum.

Data controller: Volkan Çoban (GlossaSub developer), app@glossasub.com. See also Data sharing, Data deletion and the KVKK notice.

What stays on your device (never sent to us)

Your PlayStation Network (PSN) account and password: sign-in happens on Sony's own page; GlossaSub never sees or stores your password.
API keys you enter yourself (Gemini, Claude, ElevenLabs): stored only in your device's Keychain.
The game picture: subtitles are read on your device; the picture is never sent to any server.
Your translation history and personal language packs.

What our server keeps

Anonymous user ID: the identifier the App Store gives the app (not your name, e-mail or Apple account). Used to recognise your subscription and usage allowances.
Usage statistics: durations (translation, TV, dubbing), character and request counts, the name of the game played, cost. Used to calculate allowances and improve the service.
Purchases: Apple-signed subscription records (product, expiry date). Your payment details stay with Apple and never reach us.
Abuse prevention: an irreversible hash of your IP address (not the address itself), counted per day.
Support messages: the message you write in the in-app "Support and feedback" form, your e-mail address if you enter one, and — if left on — diagnostic information (app and iOS version, device model, language and settings; no PSN details or keys). Used only to reply to you and improve the app; you can ask for deletion at app@glossasub.com.

Translation and voice services

When built-in AI translation and dubbing are on, the subtitle text to be translated or voiced is passed through our server to Anthropic (Claude), Google (Gemini) and ElevenLabs; no personal information is added. The text is subject to these services' own privacy terms; we do not store subtitle text. If you use your own key, the text goes directly to your own account.

Tracking and advertising

GlossaSub does not track you across other apps or websites, does not use the advertising identifier and does not sell your data.

Retention and deletion

Usage statistics and support messages are kept for at most 24 months and then deleted automatically; purchase records are kept as long as required by law. You can ask for deletion at any time: see Data deletion.

Your rights (EEA, UK and elsewhere)

We process data to provide the service you asked for (contract) and, where needed, on our legitimate interest in preventing abuse. You have the right to access, correct, delete, restrict or port your data and to object to processing, and to complain to your data protection authority. Data is processed on Cloudflare's global infrastructure and by the AI providers listed under Data sharing; international transfers rely on the providers' standard contractual clauses. Contact: app@glossasub.com

Children

GlossaSub is not directed at children under 13 and does not knowingly collect data from them.
