Flying Blue Doxie’s EV Logger

English한국어

End User License Agreement

Effective September 30, 2026.

The short version

  • EV Logger is free, pre-release and run by one person. It may change or stop at any time.
  • It is not made by Tesla or Rivian and is not affiliated with them. It relies on their systems, which they can change.
  • Its data can be missing, late or wrong. Never use it where money, safety or a legal claim depends on it.
  • Your data is yours. The Operator does not sell it, and you can export or delete it.
  • You must be 18 or older, and allowed to access any vehicle you connect.

1. This agreement

Flying Blue Doxie EV Logger (the Service) is a website that records and shows data from electric vehicles. Its operator (the Operator) runs it as a personal, non-commercial project.

This agreement is a contract between you and the Operator. You accept it by creating an account or by continuing to use the Service after it has been shown to you. If you do not accept it, do not use the Service. You may delete your account at any time.

2. Who may use the Service

  • You must be at least 18 years old.
  • Accounts may be by invitation. An invitation is personal to you, and you may not sell it or pass it on.
  • You may connect a vehicle only if you own it or its owner has allowed you to access its data. Where the law requires it, you must tell anyone else who drives it that its location and use are recorded.
  • You are responsible for making sure your use is lawful where you live.

3. What the Service does

The Service connects to your vehicle maker's systems with the access you give it. It collects your vehicle's location, drives, charging, battery, climate, sleep and software versions, stores them, and shows you figures and charts made from them.

The Service is independent. Tesla, Inc. and Rivian Automotive, Inc. do not endorse or support it. Their names are used only to say which vehicles it works with. The makers can change, restrict or end the interfaces the Service depends on at any time, including Tesla's Fleet API, so any feature may stop working, for a while or for good.

4. Your vehicle-maker account

  • The Service stores the access tokens the maker issues, encrypted. It does not store your vehicle-maker password.
  • Your agreement with the vehicle maker is between you and the maker. The maker may limit, lock or suspend your account or your vehicle's connected features because of third-party access. You accept that risk, and the Operator has no control over it.
  • The Service does not send your vehicle any command or control it. Collecting data may still raise the energy a parked vehicle uses.

4.1 Tesla's Fleet API

  • The Operator has registered an application with Tesla, named EV Logger at ev.flyingbluedoxie.com, and accepted Tesla's Fleet API Agreement for it. You sign in on Tesla's own pages and allow it to read your vehicle's information and location.
  • Before you sign in, the Service asks for your consent to the processing of your personal data by the Operator and by Tesla, and separately for the collection of your vehicle's precise location. Without that consent, no Tesla sign-in starts and no vehicle is added.
  • Tesla is a separate controller of what it collects about the use of its interface, under the Tesla Customer Privacy Notice (tesla.com/legal/privacy). Tesla may restrict or end the Operator's application, which ends collection for every vehicle connected through it.
  • Your vehicle sends its data only after you add the application's key to it in the Tesla app. You can remove the key at any time.
  • The Operator decides which of the data you allowed your vehicle sends, and how often, and may limit or stop it at any time. You are not charged for it.
  • A vehicle is collected on one account at a time. Its owner may move it to their own account. A driver sees it through the owner's Invite to Share.
  • To stop, remove the vehicle (Database › Clear Data › Clear All Data) or delete your account. The Service first asks Tesla to remove the vehicle's data setting, and your consent is withdrawn. If Tesla cannot be asked at that moment, the deletion waits and you can try again. You can also remove EV Logger from your Tesla account's third-party apps and its key from the vehicle.

5. Your account

Keep your password, two-factor codes, recovery codes and the devices that hold your passkeys to yourself, and trust only a browser no one else uses. Tell the Operator promptly if you believe someone else has used your account. You are responsible for what is done through it. An account may lock after repeated failed sign-ins.

6. Your data

  • The data collected from your vehicle is yours. The Operator does not sell it and shares it only as the privacy notice describes.
  • You can export it, and delete it or your whole account, from within the Service. Deletion and Clear Data are permanent. Keep your own copies of anything you would not want to lose.
  • An exported file can hold your whole location history. Once downloaded, keeping it safe is up to you.
  • If you allow someone through Invite to Share, they see everything the Service shows about the vehicles you chose, including location history, but cannot change it. You decide whom to allow and are responsible for that choice. If someone shares with you, that data is theirs: look at it for yourself only, and do not copy it out, pass it on, or use it to track a person.

7. Known limits

You accept the following risks. To the fullest extent the law allows, the Operator is not responsible for any loss that results from them.

  • Data may be missing or lost. Drives, charges and readings may not be recorded, for example while the vehicle is out of coverage, the maker's systems are down, or the Service is being updated. Recorded data may be lost, duplicated or changed. Backups are best effort. Imports and exports may fail or be partial.
  • Figures may be wrong. Many are estimates, such as energy, efficiency, cost, range, battery health and idle drain. They depend on the maker's readings, which the Operator does not verify. One journey or charge may be split or joined, and figures may differ from the vehicle, the maker's app or a bill.
  • Information may be out of date. What the Service shows about the vehicle now may be minutes or hours old. Addresses, place names and maps come from third parties and may be wrong. Vehicle pictures may not match your vehicle.
  • Do not rely on the Service for safety, security or theft tracking, diagnosis or repair, insurance or warranty claims, evidence in a dispute, valuing a vehicle, or locating a person. Nothing in it is professional advice. Do not use it while driving.

7.1 Never where money could be lost

YOU MUST NOT USE THE SERVICE, OR ANY FIGURE, EXPORT OR OTHER OUTPUT OF IT, FOR ANY PURPOSE IN WHICH ITS BEING MISSING, LATE, INCOMPLETE OR WRONG COULD CAUSE ANYONE A FINANCIAL LOSS, WHETHER OR NOT THAT PURPOSE IS LISTED HERE.

For example, do not use it to claim business mileage, a tax deduction or a reimbursement, to bill anyone for driving or electricity, to show compliance with a lease, loan, insurance or warranty mileage limit, to dispute a charge, to choose an electricity plan or budget for energy, to decide whether or at what price to buy, sell, lease, repair or insure a vehicle, or in any business such as a fleet, rental, delivery or ride-hailing operation. If you do, you act entirely at your own risk, and to the fullest extent the law allows the Operator is not responsible for any financial loss.

8. Free, pre-release, and without a support commitment

The Service is free and in a pre-release state. There is no promised availability, response time or fix. Features may be added, changed or removed at any time. If the Service is ever offered commercially, it will be under new terms you will be asked to accept.

9. Acceptable use

Do not connect a vehicle you are not allowed to access, track a person without the right to do so, use data shared with you for anything but viewing it yourself, probe, attack or overload the Service, collect data from it by automated means, copy, resell or offer it to others, or use it in breach of any law.

The Operator gives you a personal, revocable, non-exclusive, non-transferable licence to use the Service under this agreement. The Service, its software and design belong to the Operator. Third-party and open-source components keep their own licences.

10. Disclaimer of warranties

THE SERVICE AND EVERYTHING IT SHOWS ARE PROVIDED AS IS AND AS AVAILABLE, WITH ALL FAULTS AND WITHOUT WARRANTY OF ANY KIND. TO THE FULLEST EXTENT PERMITTED BY LAW, THE OPERATOR DISCLAIMS ALL WARRANTIES, EXPRESS, IMPLIED OR STATUTORY, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ACCURACY AND AVAILABILITY, AND DOES NOT WARRANT THAT DATA WILL BE RECORDED, KEPT OR RECOVERABLE.

11. Limitation of liability

TO THE FULLEST EXTENT PERMITTED BY LAW, THE OPERATOR IS NOT LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF DATA, USE, PROFIT OR SAVINGS, HARM TO A VEHICLE'S BATTERY, RANGE OR CHARGE, ACTION A VEHICLE MAKER TAKES AGAINST YOUR ACCOUNT OR VEHICLE, OR DECISION MADE IN RELIANCE ON THE SERVICE. THE OPERATOR'S TOTAL LIABILITY FOR ALL CLAIMS WILL NOT EXCEED THE GREATER OF WHAT YOU PAID FOR THE SERVICE IN THE TWELVE MONTHS BEFORE THE CLAIM AND US $50.

Nothing in this agreement limits liability that the law does not allow to be limited, such as for fraud, wilful injury or gross negligence, or consumer rights that cannot be waived.

12. Disputes with others

A dispute you have with a vehicle maker, charging provider, insurer, another user or anyone else is between you and them. To the extent the law allows, you release the Operator from claims arising from it. If you live in California, you waive California Civil Code Section 1542, which says that a general release does not cover claims the releasing party does not know or suspect to exist when releasing.

13. Your responsibility to the Operator

To the extent the law allows, you will defend and reimburse the Operator for any third-party claim arising from a vehicle you connected without authority, your recording or sharing of another person's location or use of a vehicle, or your breach of this agreement, of the law, or of your agreement with a vehicle maker.

14. Ending

You may stop using the Service and delete your account at any time. The Operator may suspend or close any account, or discontinue the Service, at any time. Where practical, the Operator will give you notice and time to export your data first. Sections 6, 7 and 10 to 18 continue after your use ends.

15. Changes to this agreement

The Operator announces material changes before they take effect, by email or by a notice shown when you sign in, unless a change must take effect sooner for legal, security or safety reasons. If you keep using the Service after a change, you accept it. If not, stop using it and delete your account.

16. Users outside the United States

The Service is run from and hosted in the United States, and is not designed to meet the laws of other countries. If you use it from elsewhere, you are responsible for complying with your local law. Consumer rights your country's law does not allow to be waived are not taken away.

17. Governing law

California law governs this agreement. Any claim must be brought in the state or federal courts in Riverside County, California, or in small-claims court, and to the extent the law allows, within one year after it arose. A consumer outside the United States keeps the protection of mandatory local law.

18. General

This agreement and the privacy notice are the whole agreement about the Service. If a part is unenforceable, the rest stays in force. Not enforcing a right does not waive it. You may not transfer this agreement. The Operator may, including to a company formed to run the Service, and will tell you. The Operator is not liable for failures caused by things outside the Operator's reasonable control, such as vehicle makers or hosting, network and mail providers. The English version controls over any translation.
