Cookie Policy

Last Updated: October 2, 2026 Version: 2.5.0

What Are Cookies?

Cookies are small text files that a website stores on your device. We also use similar browser storage. This policy covers both.

Strictly Necessary

These keep Viszy working and secure, and are set without asking:

• Sign-in and session cookies that keep you logged in and protect your account
• Security cookies that protect forms and requests
• viszy_guest (24 hours): a random id that ties your one free try, made before you sign up, to your browser so you can get the result back and save it. It is sent only to the free-try routes
• Your preferences, such as theme
• viszy_currency (first party, one year): set only if you pick a currency, for example GBP or USD, on the pricing or checkout page. It holds only that currency code, no personal data, and is not used for analytics
• cookie-consent-id: a random id that links your cookie choice to its record

Analytics (only if you accept)

• Google Analytics and Google Ads cookies, which measure how the site is used and whether an advert of ours led to a sign-up, a trial or a purchase
• viszy_click_ids (first party, 30 days): the Google Ads click id (gclid, gbraid or wbraid) of the advert that brought you, passed with your checkout so the purchase can be credited to that advert
• viszy_attribution (first party, 30 days): the campaign tags and referral id of the link that first brought you, so a referrer can be credited if you sign up
• Error reports from your browser to Sylphx Observability, our own error service

Viszy shows no adverts to you. The Google Ads cookies above only measure the result of our own adverts, and Google sets them only after you accept. If you reject, none of them is set and nothing is sent to Google.

Your Choice

When you first visit, we ask whether you accept analytics cookies. You can change your choice at any time with Cookie settings in the site footer, which reopens the question showing your current choice; changing it takes effect at once, and withdrawing consent stops the analytics and deletes the analytics cookies Viszy set. You can also block cookies in your browser settings. Blocking strictly necessary cookies may stop Viszy from working.

When you accept or reject, we keep a record of your choice as evidence of it: the choice, this policy's version, the time, and the random id stored on your device (cookie-consent-id). If you are signed in, the record also carries your account and is deleted with it.

Third-Party Pages

Our payment processor, Stripe, sets its own cookies on the checkout pages; see Stripe's privacy policy.

Updates to This Policy

We may update this policy. We post the new version here with a new date, and ask again before setting any new kind of non-essential cookie.

This cookie policy is effective as of October 2, 2026.
