Cookie policy

This policy explains how ConV uses cookies and similar storage on your device. ConV is architected to process images locally in your browser; cookies are only used where necessary for security and billing, not for invasive advertising tracking.

Essential and functional use

We use essential cookies and similar technologies only where required to operate the website securely and to remember your subscription relationship after Stripe checkout. These technologies do not collect image contents from your device.

We do not use advertising cookies. We do not deploy invasive cross-site trackers for ads.

Billing and session cookies

After a successful Stripe subscription checkout, we may set a first-party, HTTP-only cookie containing a Stripe customer identifier so our server can apply the correct plan tier when you use the Service. This cookie is not readable by scripts on the page and is not used for advertising.

Your browser or our hosting infrastructure may set short-lived security or session cookies as part of standard web delivery (for example to maintain a secure connection or to mitigate abuse). Such cookies are necessary for the integrity of the Service.

Optional privacy-friendly analytics

If privacy-friendly analytics are enabled for a deployment, they are configured to minimise personal data and avoid ad-tech ecosystems. Where analytics are disabled, no analytics cookies are set for that purpose.

Cookie table

Security / session (if set)	Short-lived cookies or tokens used by the hosting stack for transport security, abuse protection, or operational session continuity.	Session or short-lived
localStorage (tool)	Presets and ZIP path preferences stored only in your browser — not HTTP cookies. Not sent to our servers.	Until cleared by you

Exact names of security cookies may vary by deployment. For privacy rights and processing details, see our Privacy Policy.
