Novel Browser ("the App") is a web browser with AI-powered translation capabilities. This Privacy Policy explains how your data is handled when you use the App.
The App processes data only as described in this Policy. Translation text may pass through our translation service and an AI provider as described in Section 3. Hashed device identifiers and quota or rewarded-ad usage records are handled as described below.
When you use translation through our translation service (free or subscription), the App collects your device's Android ID, hashed with SHA-256 before transmission. The original value is never stored or sent. We store the hashed identifier and the amount of translation usage associated with your device on our translation service servers until you request deletion (Section 9). The base free allowance is not reset on a daily schedule. Rewarded-ad allowance is tracked separately from the base free allowance and may include a limited carryover period.
Purpose: To provide fair-use translation limits without requiring user account creation.
If you choose to watch rewarded ads, Google AdMob may collect your Advertising ID (AAID) and related data for ad delivery. Completing a rewarded ad may increase your translation allowance through our translation service. We store ad view counts and rewarded-ad allowance usage associated with the hashed device identifier to apply and enforce that allowance.
When you use translation, text visible on the current page and selected for translation is sent off your device for processing. The App cannot determine whether that text contains personal or sensitive information. Depending on your plan:
Our translation service does not store translation text. The currently contracted AI processing service states that it does not store inputs or outputs and does not use customer data to train, retrain, or fine-tune hosted models.
Text is sent only when you activate translation or a translation setting you enabled triggers it. Do not translate pages containing sensitive information unless you agree to this processing.
For BYOK, processing and retention are also governed by the policy of the provider you configure:
The following data is stored locally on your device and is not transmitted to us as personal data:
The App uses GeckoView (Mozilla's browser engine). Websites you visit may set cookies as in any browser. You can clear cookies and site data in Settings.
The App may use third-party components for browsing, advertising, payments, optional crash reporting, and translation routing. Each provider handles data under its own policies.
We do NOT sell, rent, or share user data with third parties for marketing. Data that leaves your device for our service consists of the hashed device identifier and usage data for quota management, text you choose to translate, and advertising identifiers processed by AdMob when you interact with ads.
The App is not directed at children under 13.
Delete local data in Settings → Privacy & Data, clear translation cache, or uninstall the App.
Server-side quota data includes hashed device identifiers, translation service usage records, ad view counts, and rewarded-ad allowance usage. It is retained until you request deletion. Email badmumyo@gmail.com with your Deletion Request ID from Settings → Privacy & Data, or see Data Deletion.
Upon deletion, usage records are erased. To prevent abuse, we may retain a hashed device identifier and a free-tier-used flag (not personally identifiable). Free translation quota is not restored after deletion.
We may update this Privacy Policy from time to time. Changes will be reflected in the App and on this website.
