Cookie Policy

Last updated : · v2026-05-28-v1

A cookie is a small file placed on your device (computer, smartphone, tablet) by the site or app you visit. It stores limited information (session ID, language preference, cart state, etc.) so the service can function or remember your choices.

Other equivalent technologies (local storage, pixels, beacons, device identifiers) may be used for the same purposes. In this policy, the word “cookie” covers all such trackers.

2. Cookies used on Blisterr

Blisterr uses a minimal number of cookies, grouped into three categories.

Essential for the service to work. They cannot be disabled without rendering the platform unusable.

  • Session and authentication cookies (HttpOnly tokens, logged-in user identifier).
  • CSRF and security cookies (defence against injection or impersonation attacks).
  • Language preference cookie (fr/en).
  • Cookie storing your consent choices.
  • referral_code cookie: dropped only when you land on the site via an explicit invitation link (/invite/<code>). It ensures you are correctly associated with the referrer at signup. Lifetime: 90 days max.

Issuer: Blisterr. Lifetime: from session to 12 months max (90 days for referral_code). Legal basis: contract performance and legitimate interest in security.

Help us understand how the platform is used so we can improve usability and performance. Blisterr favours privacy-respecting tools (aggregated metrics, IP anonymisation, no cross-processing).

  • Internal audience metrics (volume, journeys, bounce rate).
  • Technical performance and error monitoring (latency, crashes).

Issuer: Blisterr and analytics providers. Lifetime: 13 months max. Legal basis: consent.

Used only with your consent. They let Blisterr and its partners measure ad campaign effectiveness and, where applicable, surface relevant content on third-party sites.

  • Conversion tracking (Meta, Google, TikTok) if enabled.
  • Advertising retargeting if enabled.

Issuer: third-party providers. Lifetime: 13 months max. Legal basis: consent.

3. Your choices

On your first visit, a banner lets you accept or reject all non-strictly-necessary cookies, or customise your choice by category.

  • Accept enables every category.
  • Reject keeps only strictly necessary cookies.
  • Customise lets you allow cookies one by one, category by category.

Rejecting non-essential cookies has no impact on access to the service or on the platform’s core features.

4. Change your preferences at any time

You can change or withdraw your consent at any time:

  • Via the “Manage my cookies” link at the bottom of every page.
  • From your Blisterr account settings (Privacy section).
  • From your browser settings, which let you delete existing cookies and block future ones.

Withdrawing consent takes effect immediately for future processing; it does not affect the lawfulness of past processing.

5. Retention period

The maximum lifetime of a non-strictly-necessary cookie is 13 months, in line with the French data protection authority (CNIL) recommendations. The data collected through these cookies (audience metrics, statistics) is kept for 25 months maximum, then deleted or anonymised.

6. Third-party cookies and transfers outside the EU

Some cookies are issued by third-party providers (notably Stripe for payment security, Cloudflare for network protection, and where applicable Meta, Google, TikTok for marketing tools). When such a provider may transfer data outside the European Union, Blisterr relies on appropriate contractual safeguards (Standard Contractual Clauses adopted by the European Commission) or on the EU-US Data Privacy Framework where it applies.
