Privacy Policy
Last updated ·
Your trust is our priority. Wattly is built with a privacy-by-design approach — your data is secure and you're always in control.
27 September 2026: this update clarifies MCP permissions, optional preferences and beta routines, retention and revocation. This policy provides information; accepting it or continuing to use Wattly is not blanket consent to optional processing.

Legal Basis for Processing
We process your data based on:
- Contract performance (Art. 6(1)(b) GDPR): to provide the features you request, including necessary processing for authorized web and MCP connections, commands and, where available, routines.
- Consent (Art. 6.1.a GDPR): to send push notifications (revocable any time).
- Legitimate interests (Art. 6(1)(f) GDPR): to secure the service, prevent abuse and duplicate commands, and diagnose faults, subject to your rights and interests. You may object on grounds relating to your particular situation by contacting privacy@wattly.tech.
How We Use Your Data
We use your data exclusively to:
- Display statistics and information about your vehicle in the app
- Provide requested features (charging analytics, trip tracking, vehicle commands)
- Send notifications about your vehicle status (if authorized)
- Improve app stability and performance
- Enable community and social features (leaderboards, competitions)
Third-Party Services
We use the following third-party services that may process data:
By using Wattly and connecting your Tesla account, you acknowledge receipt of the Tesla Customer Privacy Notice and consent to the processing of your Personal Data by Tesla in accordance with that Notice. Tesla may collect information called by the API (including location data) for the purposes described in Tesla's privacy documentation.
Maps are provided by Mapbox, whose SDK can collect anonymized usage and approximate-location telemetry to improve its services. In Wattly this telemetry is disabled by default; you may opt in (or back out) at any time via the info (ⓘ) button shown on any map.
AI assistants and MCP
When you connect an assistant, Wattly shares responses about your selected vehicles with its provider: saved status, trips, charging, costs, battery and maintenance data, within the permissions you grant. Location sharing is optional and off by default. Vehicle control and waking require separate permissions; requested actions send necessary command data to Tesla. Automatic waking is a separate preference, off by default. Sensitive vehicle controls require an additional permission.
We store your connection preferences and, where available in the restricted beta, the plans, routine instructions, schedules, vehicle, confirmations and execution history needed to provide those features. An approved routine can run after the chat closes. Revoking the connection prevents further access and execution, but cannot recall an action already committed for dispatch or sent.
The assistant receives scoped MCP tokens, never your Wattly session credentials or Tesla tokens. Access tokens last 15 minutes; refresh tokens last 30 days and rotate when used. Disconnecting in Wattly immediately invalidates the connection. Signing out of the website does not disconnect assistants.
The provider processes shared information under its own privacy policy, settings and retention rules, potentially outside the EU. Disconnecting does not erase information already shared with it; use the provider’s controls to manage those copies. This policy does not determine the provider’s use of that information.
International Transfers
Your data is processed on servers located in the European Union. Some third-party services (Tesla, Mapbox, Sentry, Google Firebase) may process data in the United States under appropriate transfer mechanisms (Standard Contractual Clauses or adequacy decisions).
Data Retention
- Account data: until you request deletion or delete your account.
- Vehicle data: up to 2 years from collection, or until you delete your account.
- Trip history: retained for analytics; deleted upon account deletion.
- Credentials: Wattly account and vehicle credentials use protected device or server storage according to their purpose. Assistants receive only separate, scoped MCP tokens.
We store token hashes, permissions, selected vehicles, connection dates and preferences. Connection and command records, including duplicate-prevention records, and available plans, routines and execution history are retained without an automatic age-based purge until account deletion, to operate these features and preserve security, quota and execution records. Revocation or cancellation changes their status; it does not erase this history.
Expired authorization requests and codes, and token records whose refresh validity has expired, become eligible for periodic cleanup after a one-day margin. Temporary encrypted confirmation secrets are cleared on dispatch or by periodic and on-access cleanup when expired, no longer approved or linked to a revoked connection; revocation does not promise immediate physical erasure of those records.
MCP operational logs record the tool, duration, result category and internal connection identifiers, not tokens, coordinates or response contents. Logs rotate according to size limits; no fixed day-based retention period is promised here. Account deletion and its limited exceptions are described below.
Your Rights (GDPR)
Under the General Data Protection Regulation, you have the right to:
- Access: request a copy of your personal data.
- Rectification: correct inaccurate data.
- Erasure: delete your account and all data (“right to be forgotten”).
- Portability: receive your data in a structured, machine-readable format.
- Object: object to certain types of processing.
- Restriction: restrict processing under certain circumstances.
You can exercise these rights from the app's “Settings” section or by contacting us at privacy@wattly.tech.
Account Deletion
You can request deletion of your account and associated data in the app’s “Settings” or by emailing privacy@wattly.tech.
A minimal deletion audit, including a protected hash of the email address, is retained for 365 days for security and then purged. Limited technical coordination records may remain after an interrupted operation. Backup copies are removed through scheduled rotation, with daily backups retained for up to 90 days. Deleting your Wattly account does not delete copies already held by an assistant provider; contact that provider to manage them.
Cookies & Tracking
With your permission, we use Google Analytics and Meta and X pixels to measure visits and advertising conversions. You can decline or change your choice at any time.
Google Firebase Analytics (iOS). We use analytics to improve Wattly and measure our campaigns.
Children's Privacy
Wattly is not intended for use by children under 16. We do not knowingly collect personal data from children. If you believe a child has provided us with personal data, please contact us immediately.

We protect your data through:
Changes to This Policy
We may update this Privacy Policy and will notify you of significant changes through the app or by email. The updated date identifies the current version. Where processing requires consent, we will request it separately; continuing to use Wattly does not replace that consent. You can withdraw optional consent using the relevant controls.
Sensitive Information
Wattly does not collect, process or use any sensitive personal information as defined by data-protection law, including:
- Health or medical conditions
- Political affiliations or beliefs
- Race or ethnic origin
- Religious or philosophical beliefs
- Sex or sexual orientation
- Trade-union membership
- Genetic or biometric data
We do not use vehicle data to infer or derive any such sensitive information about you or anyone else.
