Eye-Posture Break Reminder

# Privacy & Usage Policy — Eye & Posture Break Reminder

**Effective date:** 2026-07-19

**Extension:** Eye & Posture Break Reminder (Chrome / Microsoft Edge)

This extension is built to be **100% local**. It does not have a backend server,

it does not create an account, and it does not transmit your data anywhere. This

document explains exactly what the extension does and does not do with your

information.

---

## 1. Summary

- **No data collection.** We do not collect, transmit, sell, or share any

personal data.

- **No tracking or analytics.** There are no analytics SDKs, trackers, cookies,

fingerprinting, or telemetry of any kind.

- **No network requests.** The extension makes no `fetch`/XHR/WebSocket calls to

any server. It only reads files packaged inside the extension itself.

- **Everything stays on your device / in your browser account.**

## 2. What data the extension stores (locally)

The extension stores only the information needed to work, using the browser's

own storage APIs:

| Data | Where it is stored | Purpose |

|---|---|---|

| Your settings (reminder intervals, on/off, schedule, snooze length, language, etc.) | `chrome.storage.sync` | Remember your preferences |

| Break statistics (today's completed breaks, day streak, dates) | `chrome.storage.local` | Show your local stats |

| Runtime state (paused flag, snooze timers) | `chrome.storage.local` | Keep reminders working correctly |

We (the developer) never receive any of this. There is no server to send it to.

### About settings sync

Settings are saved with `chrome.storage.sync`. If you are signed into your

browser (Google Chrome / Microsoft Edge) **and have sync enabled**, your browser

vendor synchronizes these settings across your own devices. That synchronization

is performed by Google or Microsoft under **their** privacy policy — the

extension developer has no access to it. If you are not signed in or sync is off,

the settings simply stay on the current device.

## 3. Permissions and why they are used

The extension requests only these four permissions:

- **`alarms`** — schedule the periodic eye, posture, and rest reminders reliably.

- **`storage`** — save your settings and local statistics (see section 2).

- **`notifications`** — display the reminder prompts.

- **`idle`** — optional feature: skip reminders while you are away from the

computer (only active if you enable it).

The extension requests **no host permissions** and includes **no content

scripts**. It therefore **cannot read, modify, or access the content of any web

page you visit.** Break screens and the recommendations page are the

extension's own pages.

## 4. Links that leave the extension

The extension never navigates anywhere on its own. Two features open an external

site **only when you click them**, in a new browser tab:

- **Recommended gear (Amazon).** The "Recommended gear" page shows a few optional

products. As an Amazon Associate, the developer may earn from qualifying

purchases. This is disclosed on that page at all times. Amazon links open only

when you click a product; no affiliate code is ever injected into other pages,

and no tags on other sites are modified.

- **Support (Ko-fi).** The "Support this project" button opens a donation page

(Ko-fi) in a new tab.

Once you visit Amazon or Ko-fi, those third-party sites are governed by **their

own** privacy policies, not this one.

## 5. Children's privacy

The extension does not collect any personal information from anyone, including

children. It is safe to use at any age with respect to data privacy.

## 6. Data retention and deletion

All data is stored locally by your browser. You are always in control:

- Removing/uninstalling the extension deletes its local data.

- Clearing your browser's extension data removes stored settings and statistics.

- Disabling browser sync stops cross-device synchronization of settings.

## 7. Changes to this policy

If this policy changes, the "Effective date" above will be updated and the new

version will be published in the extension's repository. Material changes will be

reflected before or at the time they take effect.

## 8. Contact

For questions about this policy or the extension, you can reach the developer via

the Ko-fi page:
