Battery Warning — Privacy Policy
Effective date: August 1, 2026
Summary: Battery Warning reads your device's battery level and charging status, using Chrome's Battery Status API, only to decide when to show an on-screen warning and play an audio alert. Battery Warning does not read, collect, or transmit webpage content, browsing history, or personal data, and does not send battery information to PurpleTools, ExtensionPay, Stripe, advertisers, or data brokers. ExtensionPay receives limited account and subscription information solely to provide trials, payments, login, and license verification.
1. Scope
This policy describes how the Battery Warning Chrome extension ("Battery Warning," "the extension," "we," "us") accesses, uses, stores, and shares information.
2. Information Processed
| Category | How it's used | Where stored/processed |
|---|---|---|
| Battery level & charging status | Read via Chrome's Battery Status API on an even-minute clock interval, to decide when to show the warning and play tinks | Processed entirely in the browser; never transmitted or stored on our servers |
| Consent record | Whether the user accepted the in-extension data-use disclosure, its version, and acceptance time | Stored locally via Chrome extension storage |
| Trial/account/subscription info | ExtensionPay may process an access key, install date, email (if supplied), trial start date, paid status, subscription status, plan details, cancellation date — to provide trial, payment, login, and license verification | Sent over HTTPS to ExtensionPay; cached locally in Chrome extension storage for verification |
| Payment information | Entered directly on pages hosted by ExtensionPay and Stripe | We never receive or store full payment-card data |
3. How Information Is Used
Only to provide, maintain, and secure the warning functionality, verify trial or paid access, process subscriptions, and respond to support requests.
4. Information Sharing
We don't sell data. We don't share battery info, webpage content, or browsing activity with ExtensionPay, Stripe, advertisers, or data brokers. Limited account/subscription/payment data goes to ExtensionPay and Stripe only as needed for payment/license services, or as required by law.
5. Advertising and Profiling
None. No personalized ads, retargeting, creditworthiness, or unrelated profiling.
6. Data Retention
Battery readings are transient and not retained by us. Consent status and cached access info stay in local Chrome storage until changed, cleared, or the extension is removed. ExtensionPay/Stripe retain data per their own policies.
7. Security
Uses Chrome extension APIs and HTTPS with ExtensionPay. No storage or transmission method is 100% secure.
8. Chrome Web Store Limited Use Disclosure
Use of information adheres to the Chrome Web Store User Data Policy, including Limited Use requirements: data is used/transferred only to provide/improve the disclosed single purpose, comply with law, or protect against fraud/abuse.
9. Children's Privacy
Not directed to children under 13.
