Battery Charge Benchmark — Privacy Policy

1. Who we are & what this covers

Battery Charge Benchmark ("the App") is an independent Android app operated from Toronto, Ontario, Canada by the developer publishing as jsyntax ("we", "us", "our"). This Privacy Policy explains what information the App handles, where that information is stored, and the choices you have.

The App lets you benchmark how quickly your phone charges under different conditions — different chargers, cables, cases, accessories, ambient temperatures and battery settings — by recording a charging session while your device is plugged in and charting the results.

By using the App you agree to the handling of information as described here.

2. We do not collect your information

This is the most important section, so we will be blunt: we receive nothing. The App records data on your device and stores it on your device, in a private app database that only the App can read. There is no account system, no cloud sync, no backend service, and no analytics or advertising SDK bundled into the App.

The App does not declare the Android INTERNET permission. Android enforces that at the operating-system level, which means the App cannot open a network connection to us or to anyone else, whether or not you trust this document. You can verify this yourself: on Google Play, open the App's listing and check App permissions → See more.

3. What the App records on your device

Everything below is written to the App's local database and stays there.

a. Charging & battery measurements

While a charging session is running, the App samples the readings Android exposes about your battery, including: charge level, battery health and status, instantaneous and average current, voltage, battery temperature, charger type (AC, USB, wireless), device thermal status, and whether the screen is on and whether the device is in idle or power-save mode. Each sample is timestamped so the session can be charted.

b. Device and system information

So that sessions can be compared meaningfully, each session stores the device model, brand, manufacturer, chipset (SoC) model, Android version and SDK level, and the amount of installed memory. This is standard hardware information, not an identifier we assign to you, and — as above — it is never transmitted.

c. Details you type in yourself

You can annotate a session with the equipment and conditions you were testing: charger name and wattage, wireless-charger details, cable type, name and wattage, converters used, case and accessory details, ambient temperature, ventilation, CPU-intensive apps that were running, relevant battery settings (fast charging, battery protection, adaptive battery), a name for the location, and free-form notes. These fields are entirely optional and are yours to fill in as you wish.

Because the notes field is free text, please avoid typing sensitive personal information into it. It is stored in plain form in the App's local database, exactly like the rest of your session data.

d. Approximate location — optional

If — and only if — you grant the optional ACCESS_COARSE_LOCATION permission, the App reads your device's last known approximate (network-based) location when a charging session starts, and stores the coordinates, postal code and address line alongside that session. The purpose is narrow: it saves you from re-typing where you were, so that sessions recorded at home, at the office and in the car can be told apart automatically.

Points worth knowing:

• Location is requested only as a coarse (approximate) permission — never precise GPS, and never in the background outside a charging session.
• The App reads the location Android has already cached; it does not activate GPS to obtain a new fix.
• To turn coordinates into a readable address, the App calls Android's built-in geocoder (android.location.Geocoder). On most devices that service is supplied by Google Play services and resolves the address through Google, under Google's Privacy Policy. This is the one point at which the operating system may contact a Google service on the App's behalf; the App itself still sends nothing anywhere, and the resulting address is stored only on your device.
• The App works fully without this permission. If you decline it, sessions are simply recorded without location, and you can still name the location yourself.
• You can grant or revoke it at any time under Settings → Apps → Battery Charge Benchmark → Permissions.

e. Notifications

The App uses a foreground service to keep sampling reliably while your device is plugged in and the screen is off. Android requires a persistent notification for this, which is why the App asks for notification permission. The notification shows the status of the charging session in progress. No notification content is sent anywhere.

4. Permissions the App requests, and why

5. How the information is used

• To chart a charging session in progress and show live battery readings.
• To save completed sessions so you can review them later.
• To compare sessions against each other — for example, how much faster one charger, cable or case charged the same device.

The information is used for nothing else. It is not profiled, scored, monetised, or used to advertise to you.

6. Sharing and disclosure

We do not sell, rent, trade or share your information — because we never receive it. There are no advertising networks, analytics providers, data brokers or affiliates involved in the App.

The only third parties in the picture are ones you already have a relationship with:

7. Android backup

The App participates in Android's standard Auto Backup feature. If backup is enabled in your device settings, Android may copy the App's data — including your saved charging sessions — to your own Google Drive backup so it can be restored when you set up a new device. That backup belongs to your Google account, is governed by Google's Privacy Policy, and is not accessible to us. You can disable it under Settings → Google → Backup, or per-app where your device supports it.

8. Retention & deleting your data

Because the data lives on your device, you control how long it is kept. It remains until you remove it. You can:

• delete individual charging sessions in the App;
• clear everything at once via Settings → Apps → Battery Charge Benchmark → Storage → Clear storage; or
• uninstall the App, which removes its local database from the device.

If Android Auto Backup is enabled, remember to clear the backup copy from your Google account as well (§7). We hold no copy to delete, so there is no deletion request to send us.

9. Security

Your session data is kept in the App's private storage sandbox, which Android isolates from other apps, and it is protected by your device's own lock screen and (on modern Android) full-device encryption. Not transmitting data at all removes the largest category of risk. That said, no method of storage is completely secure, and data on a device you have unlocked, rooted, or shared with someone else may be readable by them.

10. Children's privacy

The App is a general-audience utility and is not directed to children under 13. We do not knowingly collect personal information from anyone, children included. Since no information is transmitted to us, we hold no children's data to disclose or delete.

11. Your rights & choices

• Location: grant or revoke the optional approximate-location permission at any time in Android Settings.
• Notifications: manage or disable in Android Settings (note that Android requires the notification for background sampling to continue).
• Access & portability: all of your data is already on your device and visible to you in the App.
• Deletion: as described in §8 — the deletion is entirely in your hands.

We handle personal information in accordance with Canada's Personal Information Protection and Electronic Documents Act (PIPEDA) and applicable Ontario law. Users in other jurisdictions, including those covered by the GDPR/UK GDPR or by U.S. state privacy laws, retain their rights of access, correction, deletion and portability; in practice those rights are self-served here, because we are not in possession of your data.

12. Where information is processed

All processing performed by the App happens locally on your Android device. The App is operated from Canada. The only cross-border processing that can arise is Google's own — the system geocoder lookup if you enable location (§3d), and Google Play or Google Drive backup services (§6, §7) — which Google may perform in the United States and elsewhere under its own privacy policy.

13. Changes to this policy

We may update this Privacy Policy from time to time — for example if the App gains a feature that changes how data is handled. When we do, we will revise the "Last updated" date above and post the new version at this URL. Material changes will be made reasonably prominent. Your continued use of the App after an update means you accept the revised policy.
