Privacy policy

The email address you submit is stored as a contact in our audience at Resend (Resend, Inc., United States) and used only to send occasional emails about launches and write-ups. Signup is single opt-in — no confirmation email is sent. You can unsubscribe through the link in any email, or by writing to the contact address below.

The IP address of a signup request is used only to limit submissions to three per hour and is held in server memory for at most one hour — it is never stored in a database. A hidden field in the form catches automated submissions.

Umami, an analytics instance we host ourselves on our own infrastructure, records page views, referrer, browser, device type and country in aggregate. It does not use cookies, and the data is not shared with a third-party analytics vendor.

PostHog (PostHog, Inc., US cloud) records page views, page leaves and autocaptured clicks. PostHog stores an anonymous identifier in your browser (cookie or local storage) to distinguish sessions. We never attach a name or email to that identifier.

Sentry (Functional Software, Inc., United States) is active only on the production site. When something breaks it receives the error message and stack trace, the page URL, and your browser and operating system. When an error happens in the browser, a replay of the interaction leading up to it may be recorded, with text masked. Roughly one in ten page loads also sends performance timing data.

This site is served from a Hetzner server (Hetzner Online GmbH, Germany) behind Cloudflare (Cloudflare, Inc.), which processes connection data such as your IP address to route and protect traffic.

Our web server writes a technical request log: time, page path without the query string, status code, response time, a request ID, a coarse client type (browser, bot or monitoring probe) and a keyed hash of your IP address that changes every day (UTC) and cannot be turned back into the address. It does not record the address itself, cookies, or what you type into the newsletter form, and email addresses in error messages are masked.

Your light/dark theme choice, kept in localStorage — no personal data.

• Server request logs: 90 days on our server. Encrypted copies of the log files are kept in our disaster-recovery backup for the same 90 days.
• Encrypted nightly backups of the server: 60 days.
• Umami page-view records: on our own server; we have not set an automatic deletion period.
• PostHog and Sentry: under each provider's own retention terms. Resend keeps newsletter contacts until you unsubscribe or ask us to delete yours.
• Theme choice: in your browser until you clear its storage.

Products and external links presented on this site have their own policies. This policy covers vboldyrev.com only. We do not sell personal data.
