AlmaMesh ("we", "our", "us") is built to protect your privacy by keeping your data on your device. AlmaMesh runs entirely in your web browser, with no AlmaMesh backend server and no database we control. This Privacy Policy explains the few things that touch the network and what stays local.

1. Your Data Stays on Your Device

What You Enter

Profile Names: Names you save for charts — stored only in this browser, never sent to us
Birth Details: Date, time, and place of birth, used on-device to compute your chart and stored only in this browser
Chat Content: Questions you ask and interpretations you receive, stored only in this browser

Where It Lives

Browser Storage: All of the above is held in your browser's local storage (IndexedDB / OPFS) on this device
No Server Copy: None of it is transmitted to or stored on any server operated by AlmaMesh — we hold nothing about you

2. What Touches the Network

AlmaMesh makes the network do only two things:

Delivery only: downloading the app and a signed, content-addressed astronomy bundle (the DE421 ephemeris and program files) so the engine can run offline afterward. This is a one-way download; it carries no personal data about you.
Optional AI: if you choose to enable AI interpretation or chat, your prompt is sent to an AI endpoint — see the next section.

We do NOT:

Operate accounts, logins, or collect your email — there is nothing to sign up for
Collect, store, or process your birth details or charts on our servers
Sell your data, track you across sites, or run targeted advertising

3. Optional Third-Party AI Endpoint

AI interpretation and chat are optional and are never required to draw a chart. They work only if YOU configure an OpenAI-compatible endpoint (for example, OpenRouter or your own).
When you use AI, your prompt is PII-redacted and fail-closed, then sent to the third-party endpoint YOU chose. That request goes to that provider — not to AlmaMesh — and is subject to THEIR privacy policy and terms, not ours.
If you never configure an endpoint, no prompt ever leaves your device. The chart engine itself is zero-egress.

4. Cookies and Tracking

AlmaMesh uses no advertising or analytics trackers and no third-party cookies. The only browser storage it uses is the local storage described above, which exists solely to make the app work offline on your device.

5. Your Rights

Because your birth data never leaves your device, you are always in direct control of it:

Know. Everything AlmaMesh holds about you is visible in the app on this device — we hold nothing on a server.
Delete. Remove a profile or chart in Settings, or clear your browser's site data / uninstall the app. See the Data Deletion page.
Port. Your data lives in standard browser storage on your device, under your control.

6. Data Retention

Your data lives on your device until you delete it; we hold nothing on a server to retain or expire.
Deletion is immediate and local — removing it from this browser removes it everywhere it ever existed.

7. Children's Privacy

AlmaMesh is not intended for users under 13 years of age.

8. Changes to This Policy

We may update this Privacy Policy from time to time. We will post the new policy on this page with an updated effective date.
