Privacy Policy

AI Study Tools is operated by CNVX.

Updated 2026-10-09

This policy explains how AI Study Tools handles information when you sign in, upload material, generate study content, and use saved results.

Information we collect

Google sign-in provides a Google account identifier, email address, and name. We store these to identify your account. We do not receive your Google password or request access to Gmail or Google Drive.

We store the text extracted from your files, pasted notes, material names, generated exams and guides, source references, answers, study progress, feedback, and generation-usage records. Hosting and service providers also process technical request information, such as IP addresses and timestamps, to operate and secure the service.

What happens to an upload

Files are uploaded to our server so we can extract readable text. For cloud uploads, file chunks are temporarily stored in our Neon database. Successful processing removes those chunks; incomplete uploads expire after 15 minutes and are cleaned up when a new upload starts. The extracted text remains in your account until deleted. This service is not a backup of the original file.

AI processing

When you request an exam or guide, the source sections you selected are sent to DeepSeek with generation instructions and your output settings. Our generation request does not include your Google sign-in details. If selected text itself contains personal information, that information will be sent as part of the text. Do not upload sensitive personal information or material you are not permitted to share.

DeepSeek processes requests under its own policies. We do not promise that a provider has zero retention or uses no data for model improvement unless that has been contractually established. Review DeepSeek’s privacy policy before sending material.

Providers and storage

Vercel hosts the application, Neon stores account and study data, Google provides sign-in, and DeepSeek generates learning content. These providers may process data outside your country. Access to saved study content is restricted by account; the service does not offer public sharing of your uploaded material.

Cookies and browser storage

Essential cookies keep you signed in and secure the Google sign-in flow. Browser session storage remembers your selected material, settings, progress references, and a draft during sign-in. Local storage notifies other tabs when sign-in changes. We do not embed advertising trackers or Google Analytics.

Study tools analytics

We keep identifier-free statistical totals for rendered page views and successful or failed study actions, grouped by date, broad source category, country and device class. These totals do not contain an IP address, full URL, raw user agent, email, document text, answers or a persistent visitor identifier. They cannot identify people or connect anonymous visitors across visits. Country is a coarse hosting-provider estimate, not precise location.

In every region, basic page and button statistics use a random, first-party browser cookie for up to 30 days unless you turn analytics off in Privacy settings. This basic browser identifier is kept separate from accounts and study activity. We respect Do Not Track and Global Privacy Control. Existing anonymous events without an identifier cannot be retroactively counted as unique browsers.

Optional analytics is off unless you actively allow it in Privacy settings. When allowed, a random first-party browser identifier and a 30-minute visit identifier connect study activity and repeat visits. For signed-in activity, an account pseudonym allows repeat-use measurement across signed-in devices. This is pseudonymous, not anonymous. Analytics identifiers are not shared with advertising services. We store your choice in a preference cookie and retain each optional browser identifier for up to 90 days. While your consent choice remains valid, an expired browser identifier may be replaced with a new random identifier. You can turn optional analytics off here at any time; this removes its browser cookie and stops further linked collection. Existing analytics records follow the retention policy, or may be included in a verified data-removal request.

Linked records and operational deduplication records older than 90 days, and identifier-free daily totals older than 390 days, are removed at the next application initialization or operator report refresh. Cleanup may be delayed while the service is inactive. Data is stored using the existing Neon and Vercel services. Known automated requests, examples and marked operator tests are excluded from the default report. Hidden referrers remain unknown.

Retention and deletion

You can delete a material in the application. This removes its saved text, associated outputs, and study sessions from the active library. Account records, generation accounting, and some operational job data may remain for quota enforcement, troubleshooting, and security. Provider backups and logs have their own retention periods; removing a material is not a promise of immediate deletion from every backup or provider system.

Account deletion is not currently a self-service button. A verified account-data request requires manual handling. We cannot restore material you have deleted from the active library.

Security and your choices

We use HTTPS and account-level access checks. No online system can guarantee absolute security. You may stop using the service, delete material, and sign out at any time. Applicable privacy rights depend on your location and circumstances.

Changes

We will update this page when our data practices change. Check the date above before using the service again.

Contact and data requests

For questions or requests to access, correct, or delete your account data, contact cnvx.studio@gmail.com from your account email address. We may need to verify your identity. Do not send passwords or private study material in your request.
