Privacy Policy

Information We Collect

• Usage data: Pages visited, approximate geography (IP truncated / aggregated where feasible), device & browser metadata.
• Cookies / local storage: Basic preferences (e.g. dark mode), ads & analytics identifiers.
• Contact info: Email address & message content you voluntarily send us.

How We Use Data

• Operate and improve calculators & site reliability.
• Respond to feedback and support requests.
• Understand aggregate feature usage to prioritise enhancements.
• Serve and measure relevant advertising (via third parties).

Advertising & Third Parties

We rely on limited third‑party ad networks and analytics providers. These partners may set cookies or similar identifiers to personalise ads and gauge performance. We do not sell or directly share your personal contact info with advertisers.

Google AdSense: Third‑party vendors (including Google) use cookies & similar technologies to collect usage across sites for ad personalisation and measurement. See Google Privacy, Google Ads. Manage preferences at Google Ad Settings or use browser privacy tools.

Cookies & Local Storage

Essential: theme preference, basic session improvements. Optional/third‑party: advertising conversion & analytics. You can disable or clear cookies via browser settings; essential functionality generally remains, but personalisation may degrade.

Ads.txt Declaration

We publish /ads.txt to list authorised digital sellers; ad exchanges use this to reduce spoofing.

Your Choices & Rights

• Opt out of personalised ads (browser settings, ad settings portals, privacy extensions).
• Disable cookies or use private browsing to limit tracking scope.
• Email in.herozero@gmail.com for data questions or removal of voluntarily submitted messages.

Changes

Material updates will be posted here with a revised date. Continued use signals acceptance of the updated policy.
