Tank Heating Calculator: Privacy Policy Addendum

Version 1.0 · Effective November 11, 2026

Your use of this App is governed by the KHouse Privacy Policy (version 1.0), which applies to every KHouse app, together with this Addendum.

This Addendum adds to the KHouse Terms of Use and Privacy Policy. They apply in full except where a clause below says it changes a named section for this App.

B1. Extra data

Weather lookups: the ZIP code or coordinates you enter are sent from our server to Open-Meteo and Zippopotam.us; they receive no account identity. We do not store location queries.

B2. Data kept on your device

Tank configurations, inputs and results are processed in your browser. Saved configurations download as files to your device; PDFs are generated in your browser. We cannot see or delete them.

B3. Extra providers

B4. Usage events

This App records usage events (page views, sign-in) under base §2.

B5. Retention and deletion

Base defaults. The App stores no calculation data under your account, so deleting your KHouse account (base §8) leaves nothing behind except the usage events above.
