Rivio (“Rivio”, “we”, “us”, or “our”) is a study and productivity application designed to help users organise study materials, use a Pomodoro timer, create flashcards, and track study activity. This policy explains how information is handled when you use Rivio, including information processed by third-party advertising and analytics services.

1. Information stored by Rivio

Rivio is designed to operate locally on your device. Rivio does not require an account and does not ask you to provide personal information such as your name, email address, phone number, password, or home address to use its core study features.

Information you create or enter may include note subjects and PDF references, flashcard subjects, decks, questions and answers, Pomodoro sessions, study activity and statistics, streak information, app preferences, and settings. This core study information is stored locally using the app’s device storage and database. Rivio does not upload your study materials or locally stored study records to Rivio-operated servers for cloud storage or synchronisation.

Some app usage events and technical information may be transmitted to third-party analytics and advertising providers, as described below. Local study materials are not sold by Rivio.

2. PDF files and documents

Rivio allows you to select PDF files from your device for organisation within the app. Rivio stores a local reference to the selected document so it can be opened from the app. Rivio does not upload the contents of your PDFs to Rivio-operated servers.

PDF contents are not intended to be collected by Rivio’s analytics service. The app does not intentionally send PDF contents, document filenames, or local file paths to PostHog for analytics. You are responsible for the content of documents you choose to access through Rivio.

3. Deletion of local data

Because Rivio stores its core study data locally, deleting the app may delete the local application data associated with it. Rivio does not maintain a cloud account or server-side copy of those study materials for restoration after app data is removed.

Information already transmitted to PostHog or processed by Google AdMob may remain subject to the relevant provider’s retention and deletion practices. Deleting the app does not necessarily delete data previously sent to those providers. See the current Google Play Data safety information for the developer’s published data controls.

4. Advertising

Rivio uses Google AdMob to display advertisements. Google may process information from the device or app interaction in connection with ad delivery, measurement, fraud prevention, and related purposes. Depending on device settings, location, applicable law, and Google’s configuration, this may involve advertising identifiers, network information such as an IP address or approximate location, app or device information, and ad interactions.

The current Google Play Data safety section reports that Rivio may share Location and Device or other IDs, and may collect Location, App activity, and App info and performance. It also reports that data is encrypted in transit and that data cannot be deleted through the controls presented there. Google Play declarations and service configurations can change; consult the live listing for its current wording.

Rivio does not directly store advertising information in its local study database. Google’s handling of information through AdMob is also governed by Google’s own terms and privacy practices. Read the Google Privacy Policy .

Where required by applicable law, Google may request consent for personalized advertising and related processing. Android device settings and Google services may provide additional advertising controls. Rivio integrates Google’s consent flow for regions where a consent or privacy choice is required. The options available can vary by location and applicable rules.

6. Analytics and usage information

Rivio uses PostHog, a third-party product analytics service, to understand how app features are used and to improve the experience. Events may include app and screen views, starting or completing focus sessions, opening flashcard decks, accessing the library, and other feature interactions. Related event information can include timestamps, focus duration, completion status, card counts, app version, operating system, or other technical metadata made available by the SDK.

Rivio does not require an account for analytics and the app code does not intentionally send a user’s name, email address, phone number, note contents, flashcard questions or answers, PDF contents, or local document paths to PostHog. PostHog may process network information such as an IP address under its service configuration and privacy practices. See PostHog’s Privacy Policy .

7. Third-party services

Rivio currently integrates Google AdMob for advertising and Google’s consent tools for advertising choices, and PostHog for product analytics. These providers may process information transmitted through their SDKs on servers outside your device. Rivio does not control all processing performed independently by those providers.

8. Data security

Rivio’s core study information is stored locally on your device rather than on servers operated by Rivio. Information sent to third-party services is subject to the providers’ security practices and the relevant network and SDK configuration. The current Google Play listing reports that information is encrypted in transit. Protect your device with appropriate security settings and keep its operating system up to date. No method of electronic storage or transmission can be guaranteed to be completely secure.

9. Changes to this policy

We may update this policy when Rivio’s functionality, third-party services, or applicable requirements change. The updated version will be published here with a revised date.

In summary: core study materials and study records are stored locally; Rivio does not require an account for those core features or upload your study materials for cloud storage. Google AdMob and PostHog may process certain advertising, technical, and app usage information.
