Privacy Policy
Last updated: 2026-11-14
This policy explains how RTTS processes information when you use Realtime Subtitle & Manga Translator.
Information used to provide the service
- Email address: used for email login codes, purchase association, receipts, and support.
- Google sign-in: when you choose Google, we verify your Google account identifier and verified email address to sign you in. A Google address different from your email-code address is a separate RTTS account. Contact support if you need help with your accounts.
- GitHub sign-in: if you choose GitHub, we use your stable GitHub user identifier and a verified email address to sign you in. First-time linking may require an RTTS email code. We do not request access to your repositories. Changing your GitHub email does not move an existing RTTS account.
- Account and device identifiers: used to keep a browser installation linked to its usage balance and prevent duplicate abuse grants.
- Usage records: prepaid minutes, manga pages, or web text characters are decremented when the corresponding service is used.
- Abuse-prevention data: a one-way IP fingerprint may be used for rate limits. We do not use it as a precise location profile.
Media processing
Website access: the extension runs on supported pages to find videos, subtitles, images, manga readers, and webpage text. When you request translation, it may capture the active tab’s audio, read subtitle text, webpage text, and selected image content, or capture the visible page image for canvas manga processing.
Audio, subtitle text, web page text, and manga image crops may be sent to the configured AI providers to produce a translation. Translation results may be cached as described below. Providers handle submitted content under their own terms and retention policies; RTTS does not promise zero provider retention. The extension may cache detector model files locally in the browser.
If you connect your own AI provider, submitted API credentials are encrypted on our server and used only for requests you select. During setup, browser session storage may contain an unfinished configuration draft, including a key you entered. Drafts can be restored for up to 30 minutes and are cleared when you sign out. Your provider account pays that provider; these requests do not spend RTTS translation credits.
Browser storage keeps your sign-in session, translation settings, temporary session state, and local detector model files. Sign out to end the account session; stop translation to end active audio capture. The separate manga translation cache described below remains after sign-out.
RTTS follows the Chrome Web Store User Data Policy, including its Limited Use requirements. RTTS uses data only to provide translations requested by the user, manage accounts and billing, and perform necessary security functions. RTTS does not use this data for advertising or model training. Read the Limited Use requirements.
Service providers
Paddle processes checkout and payment information as Merchant of Record. Resend may deliver login and receipt emails. AI providers process the request payload needed to return a translation. Each provider handles data under its own terms and privacy policy.
RTTS runs its infrastructure on Cloudflare and Alibaba Cloud. Platform-funded translation currently uses Soniox and Alibaba Cloud Model Studio, with Google Gemini as a text translation fallback. When you connect your own provider, the recipient depends on the provider and endpoint you select. Provider terms and retention policies apply separately.
Retention and security
Account balance, purchase records, and limited operational logs are retained as needed to provide the service, prevent fraud, resolve disputes, and meet legal obligations. We use HTTPS and server-side secrets for provider credentials. No payment card number is stored by this service.
The browser’s manga translation cache can contain source text, translations, layout and style data, and local PNG artwork patches or masks needed to render the translated page. It has an approximately 8 MiB content budget, removes less recently used entries as space is needed, and has no fixed time limit. It is not a library of full original pages. To clear this cache while keeping account settings and detector models, contact support. Uninstalling the extension removes its local browser data.
RTTS caches subtitle text translations and manga region/diagnostic results for up to 30 days from each write. Reading a cached result does not extend its lifetime; writing a new result starts a new period. Results for identical content may be reused across users. The current manga result cache does not store full-page original images. AI providers handle transmitted content under their own terms and retention policies.
Web page text translations may be cached for up to 30 days and reused only for the same account session, webpage, source language, and target language. The original text is identified by a hash. Expired entries are removed on later access or eviction. This cache is used only to provide translations and is cleared when you sign out.
