Privacy Policy for Personal Powerwall Assistant

Version 1.3: 18th August 2025

Free-tier (monitoring only)

This Privacy Policy applies to the monitoring functionality of the Personal Powerwall Assistant (previously known as Powerwall Monitor & Terry’s Powerwall Monitor) apps and web apps.

Data Retention Policy

This app does not collect any customer user data whatsoever for the free monitoring functionality. This includes but is not limited to:

  • User Identifiers
  • Login Credentials
  • Usage statistics

Data Storage

The only data stored by this app is an ‘authentication token’ generated by the Tesla login process and only usable for this app. The token does not contain any user-identifiable information and is stored in the application’s properties on the user’s machine (or in local storage for the web application). No data is sent to or stored in any cloud storage or servers.

Further information

The app simply retrieves information from the publicly-available Tesla API based on the actions of the user in the app. This includes regular requests for current usage data, on demand requests for historical data.

Data Security

All data requested from the Tesla API is done so over a secure SSL connection. No plain text information is sent to the Tesla API from the app. Every request to the Tesla API from the app has to pass authentication using a secret key only known to the Tesla API and the app (this is the ‘authentication token’ mentioned in the Data Storage section above).

Automation tier

This Privacy Policy applies to the automation functionality of the Personal Powerwall Assistant which is carried out by servers on the Google Cloud Platform, not directly by any of the Personal Powerwall Assistant apps.

Data Retention Policy

In addition to the above details for the Free-Tier – for subscription purposes the server collects and stores email addresses but does not store any subscription payment details other than that. For clarity, no credit card, bank account, or other payment information is recorded or stored by the Personal Powerwall Assistant servers.

We do use a third party subscription provider called Stripe and users who choose to subscribe should ensure they read and agree with the 3rd party’s terms and privacy policy.

Data Storage

As mentioned in the previous paragraph, the only additional personal data stored by the automation functionality is the email address. Communications from the client applications to the automation server are only authenticated by means of an authentication token known only to the automation server and the client app.
