Last updated: 2026-05-14

Cookies are small files your browser stores so a website can remember things between page loads. OneClick uses cookies only where it actually helps. We do not run third-party advertising cookies and we do not sell tracking data.

These cookies are required for the site to work and load without your consent.

  • next-auth.session-token / __Secure-next-auth.session-token — keeps you signed in once you log in. First-party. Expires when the session ends or after 30 days, whichever comes first.
  • next-auth.csrf-token — prevents cross-site request forgery on login forms. First-party. Session.
  • __cf_bm, cf_clearance — Cloudflare bot management. Set by Cloudflare to distinguish humans from bots. Required to reach the site.
  • cookiesAccepted / cookiesDeclined — stored in your browser's localStorage so we do not ask again. First-party. Persists until you clear browser storage.

2. Functional cookies

Set when you use specific features. Off by default; enabled when you opt in or use the feature.

  • oneclick:onboarding:* — sessionStorage entries that hold your draft, chosen template, and uploaded photos during the funnel so you can refresh without losing work. First-party. Cleared when you close the tab.
  • preferredLanguage — remembers your chosen UI language. First-party. 1 year.

3. Analytics cookies

Loaded only after you accept cookies in the banner. Used to count visits and understand which pages help people, in aggregate.

  • Umami — first-party, no cross-site tracking. Stores a salted daily hash of (visitor + site + user-agent), not a persistent identifier. Hash rotates every 24 hours.
  • Vercel Web Analytics — first-party page-view counter. No personal identifier, no cross-site tracking.

4. Error monitoring

  • Sentry session-replay — sampled at less than 1% of sessions to debug rare failures. Form fields, passwords, and payment inputs are masked before transmission. You can disable replay entirely by declining cookies.

5. What we do NOT use

  • No Google Analytics, no Google Tag Manager.
  • No Facebook Pixel, no LinkedIn Insight Tag, no TikTok Pixel.
  • No cross-site advertising cookies.

6. Controlling cookies

  • The banner at the bottom of the page lets you accept or decline non-essential cookies on first visit.
  • Clear browser storage to be asked again, or to revoke a previous choice.
  • Most browsers also let you block or delete cookies in their privacy settings. Blocking strictly necessary cookies will break sign-in.
