Privacy Policy

Effective date: 2026-07-13 · Last updated: 2026-07-13

Serenido (“we”, “our”) is a small independent publisher of printable workbooks and free browser tools. We collect as little personal information as possible, this page explains, in plain language, exactly what we do and don't do with your data.

What we collect (and what we don't)

• Newsletter email (optional). If you subscribe, your email address is stored by our email service provider, not on this website. We use it only to send the newsletter you asked for. Every email includes a one-click unsubscribe.
• Tool data stays in YOUR browser. The free tools (ADHD Tax Calculator, 24-Hour Parking Lot, Dopamine Menu Builder) save their data in your browser's local storage on your own device. Nothing you type into the tools is ever transmitted to us or anyone else.
• No accounts, no passwords. This site has no login and stores no user profiles.
• No advertising trackers. We do not run ad networks or sell data. Ever.

Third parties we rely on

• Etsy, purchases happen on Etsy, under Etsy's own privacy policy and buyer protections. We never see your payment details.
• Google Fonts, our typefaces load from Google's servers, which receive your IP address as part of serving the font files.
• Email service provider, stores newsletter subscriptions securely on our behalf.
• Hosting/CDN, our host may keep standard, short-lived server logs (IP address, page requested) for security and abuse prevention, as virtually all websites do.

Your rights

You can unsubscribe from the newsletter at any time (one click), and you can email us to ask what information we hold about you or to request deletion, for most visitors the honest answer is “nothing at all.” If you are in the EU/UK, you have rights under GDPR (access, rectification, erasure, portability); if in California, under CCPA. Email us and we'll honor them.

Children

This site is intended for adults and is not directed at children under 16. We do not knowingly collect information from children.

Changes

If this policy changes, we'll update the date at the top of this page.
