Privacy Policy

Last updated: April 2026

1. Who we are

Folio Studio is an online service that allows authors to import markdown files and export them as formatted books. This service is operated by Adrien Maillard, France.

For any questions regarding your personal data, contact us at: contact@foliostudio.app

2. Data collected

Folio Studio only collects data necessary for the service to function:

  • Email address and full name (at registration)
  • Content of the projects and chapters you create and import
  • Payment data (processed by Stripe; Folio Studio never stores your bank details)
  • Technical data: IP address, browser type, access logs

3. Use of data

Your data is used exclusively to:

  • Authenticate you and secure your account
  • Store and display your projects and chapters
  • Generate your exports (epub, PDF, docx)
  • Manage your Pro subscription via Stripe
  • Send you service-related emails (confirmation, payment receipt)

We never sell, rent or share your data with third parties for commercial purposes.

4. Hosting and subcontractors

Folio Studio uses the following services:

  • Supabase (database and authentication) · EU hosting
  • Vercel (application hosting) · EU hosting available
  • Stripe (payments) · PCI DSS compliant
  • Resend (transactional emails)

5. Data retention

Your data is retained for as long as your account is active. If you delete your account, all your data will be deleted within 30 days, unless required by law.

6. Student status verification (Folio Student)

To benefit from student pricing on student.foliostudio.app, you may submit a proof of enrollment. This processing is voluntary and only affects access to the reduced pricing.

  • Data collected: photo (or PDF) of your student card or enrollment certificate, and the name of your institution.
  • Purpose: verify your student status to apply the reduced pricing. No other use. No cross-referencing with other data.
  • Document retention: the card file is permanently deleted from our Supabase storage as soon as the validation or refusal decision is made(typically within 48 business hours). Only the status ("verified until {date}") and an internal log of the decision are kept for the duration of validity (1 year).
  • Access: only the Folio Studio administrator reviews the document, via an internal backoffice. No sharing with any third party, no use to train an AI model.
  • Recommendation: you can mask your student number and ID photo before upload. Only the name of your institution and the expiration date are necessary for verification.
  • Right to object: you can opt out of verification at any time (you keep access to the free plan) or request early deletion of the document if it is still in the queue, by writing to contact@foliostudio.app.

7. Your rights (GDPR)

In accordance with the General Data Protection Regulation (GDPR), you have the following rights:

  • Right of access to your personal data
  • Right of rectification
  • Right to erasure ("right to be forgotten")
  • Right to data portability
  • Right to object to processing

To exercise these rights, contact us at contact@foliostudio.app. You also have the right to lodge a complaint with your national data protection authority.

8. Cookies

Folio Studio only uses cookies strictly necessary for the service to function (authentication session). No advertising or tracking cookies are used.

9. Changes

This policy may be updated. In the event of a substantial change, you will be notified by email. Continued use of the service after notification constitutes acceptance.
