Vizo Privacy Policy

​

Last updated: September 11, 2026

​

This Privacy Policy explains how Vizo handles information when you use the app.

Vizo is designed to analyze and display battery and charging information available on your iPhone while limiting data collection to what is necessary to provide, improve, and maintain the app.

1. Data Controller

The data controller is:

[Name / Company Name]
[Address, if applicable]
Email: [PRIVACY EMAIL]

For any privacy-related request, you may contact us using the email address above.

 

2. Data Stored on Your Device

 

Vizo may store information locally on your device that is necessary to provide its features, including:

  • battery level readings;

  • charging sessions;

  • charging duration and charging trends;

  • charger profiles and charger names created by the user;

  • associations between chargers and charging sessions;

  • app preferences and settings;

  • notification preferences;

  • Vizo Pro entitlement status.

This information is used to provide battery charts, estimates, charger comparisons, charging history, and other app features.

Detailed battery readings, charger names, and detailed charging-session data are not sent to Firebase Analytics or Crashlytics as analytics content.

Vizo does not require you to create an account.

 

3. Apple Shortcuts

 

Vizo can integrate with Apple’s Shortcuts app.

If you choose to configure the optional automations suggested by Vizo, Shortcuts may provide information to Vizo such as the battery level when a charger is connected or disconnected.

These automations are optional and are designed to improve the accuracy of charging information available inside the app.

 

4. Analytics and App Usage Data

 

Vizo uses Google Firebase Analytics to understand how the app is used and to improve its features and user experience.

Firebase Analytics may process information such as:

  • app usage events;

  • interactions with screens and features;

  • app launches and sessions;

  • Free or Pro status;

  • events related to the purchase flow;

  • technical installation or device identifiers;

  • app and operating system information;

  • approximate geographic location derived from network information.

Vizo does not use this information for personalized advertising and does not use Firebase Analytics to track users across apps or websites owned by other companies.

Firebase may use installation identifiers to associate events with the same app installation.

More information is available in Google’s Firebase privacy documentation:

https://firebase.google.com/support/privacy

 

5. Crash and Diagnostic Data

 

Vizo uses Firebase Crashlytics to identify crashes, non-fatal errors, and technical problems and to improve the stability and reliability of the app.

Crashlytics may collect information including:

  • crash stack traces;

  • app version;

  • device model;

  • operating system version;

  • technical installation identifiers;

  • crash timestamps;

  • technical information about the state of the app;

  • non-fatal errors recorded by the app.

When Firebase Analytics and Crashlytics are used together, Crashlytics may also receive information about app events that occurred before a crash to help diagnose the issue.

This information is used only for diagnostics, maintenance, and improvement of Vizo.

 

6. In-App Purchases

 

Vizo Pro is offered as a non-consumable in-app purchase using Apple StoreKit and the App Store.

Apple processes the payment directly.

Vizo does not receive or store:

  • credit or debit card numbers;

  • bank account details;

  • complete payment-method information.

The app receives only the information from Apple that is necessary to determine whether Vizo Pro has been purchased and to restore previous purchases.

Some information relating to the purchase process may also be recorded through Firebase Analytics in order to understand and improve the purchase flow.

 

7. Notifications

 

If you enable notifications, Vizo may use them to provide battery and charging-related summaries and alerts.

Depending on the features you enable, these may include:

  • charging-session summaries;

  • low estimated battery-time alerts;

  • unusual battery-drain alerts;

  • overnight battery-drain alerts;

  • battery activity summaries.

You can change or revoke notification permission at any time through iOS Settings.

 

8. Information Vizo Does Not Collect

 

Vizo does not directly collect:

  • your name;

  • your email address;

  • your phone number;

  • your contacts or address book;

  • your photos or videos;

  • audio recordings;

  • precise GPS location;

  • HealthKit health data;

  • browsing history;

  • credit card numbers or other complete payment information;

  • data for behavioral advertising.

Vizo does not include advertising SDKs and does not sell personal data to advertisers.

 

9. Purposes of Processing

 

Information processed through Vizo is used to:

  • provide the app’s features;

  • display battery history, estimates, and charging information;

  • manage Vizo Pro and in-app purchases;

  • understand how features are used;

  • improve usability and functionality;

  • diagnose crashes and technical errors;

  • maintain the reliability and security of the app.

Information is not used for third-party advertising.

 

10. Third-Party Services

 

Vizo uses third-party services necessary to operate and improve the app.

Battery readings, charging-session information, charger profiles, preferences, and similar information stored locally remain on your device until they are:

  • deleted through an available feature of the app;

  • removed when the app’s data is deleted;

  • removed when the app is uninstalled.

  • withdraw consent where processing is based on consent;

  • lodge a complaint with the competent data protection authority.

Because Vizo does not require an account and much of its information is stored only on your device, some information may not be technically identifiable by us as belonging to a specific person.

We take reasonable measures intended to protect information processed through Vizo and limit data collection to information needed to provide, analyze, diagnose, and improve the app.

However, no electronic storage or transmission system can guarantee absolute security.
