Flying Blue Doxie EV LoggerEnd User License Agreement

Pre-release edition · Effective September 30, 2026

In short

  • This is a free, pre-release personal project run by one individual, not a company. There is no support commitment and it may stop at any time.
  • It is not affiliated with Tesla or Rivian and reads your vehicle through interfaces those companies do not officially offer to third parties. It can break without warning.
  • Data can be lost or never recorded. Figures can be wrong. What you see can be out of date or misleading. Section 7 lists how.
  • Do not rely on it for safety, maintenance, insurance, warranty or legal matters.
  • Never use it for any purpose in which money could be lost, whatever that purpose is. It is not a mileage log or a financial record (Section 7.5).
  • Your data is yours. You can export it and delete it. Keep your own copies.
  • You may let one person you choose, such as someone in your household, see the vehicles you pick. They can look, never change. You decide, and either of you can end it at any time (Section 6.1).
  • You use it at your own risk, and the operator's liability is limited as far as the law allows (Sections 10 and 11).

1. The parties and this agreement

Flying Blue Doxie EV Logger (the "Service") is a website that records and displays telemetry from electric vehicles. It is operated by James Jung, an individual residing in California, United States (the "Operator", "I", "me"), as a personal, non-commercial project. The Operator is not a company, and the Service is not a commercial product.

This agreement is a contract between you and the Operator. By creating an account, or by continuing to use the Service after being shown this agreement, you accept it. 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 are by invitation. An invitation is personal to you and may not be sold or passed on.
  • You may connect a vehicle only if you own it or its owner has authorised you to access its data. You are responsible for telling anyone else who drives the vehicle that its location and use are being recorded, where the law requires that.
  • You are responsible for making sure that your use of the Service is lawful where you live.

3. What the Service is, and what it is not

The Service connects to your vehicle maker's systems with credentials you provide, collects data about your vehicle (including its location, drives, charging, battery state, climate, sleep and software versions), stores it, and shows you figures and charts derived from it.

The Service is independent. It is not affiliated with, endorsed by, or supported by Tesla, Inc., Rivian Automotive, Inc., or any other vehicle maker. Their names and marks belong to them and are used only to say which vehicles the Service works with.

The Service relies on interfaces that the vehicle makers do not officially offer to third parties, do not document, and may change, restrict or shut off at any time without notice. Any feature may stop working, temporarily or permanently, for that reason alone.

4. Your vehicle-maker account

  • To connect a vehicle you give the Service access to your account with the vehicle maker. The Service stores the access tokens it receives, in encrypted form. It does not store your vehicle-maker password; where a sign-in requires the password, it is passed to the maker and held in memory only for the few minutes that sign-in takes.
  • Those tokens can read your vehicle's data and location. You give them to the Service at your own risk. You can end the Service's access by changing your password with the vehicle maker, and you can delete your account on the Service at any time.
  • Your agreement with the vehicle maker is between you and them. The maker may consider third-party access contrary to its terms, and may rate-limit, lock, suspend or otherwise act against your account or your vehicle's connected features. You accept that risk. The Operator has no control over, and no responsibility for, what a vehicle maker does.
  • Collecting data requires contacting the vehicle or the maker's servers repeatedly. This can wake a sleeping vehicle, delay its return to sleep, and increase the energy it uses while parked. The Service may send a wake request to a vehicle. It sends no other command and does not control your vehicle.

5. Your account on the Service

Keep your password and any two-factor codes and recovery codes secret, and tell the Operator promptly if you believe someone else has used your account. You are responsible for what is done through your account. The Service may lock an account after repeated failed sign-ins; a lock is not a fault of the Service.

A passkey signs in without your password or code, and a browser you choose to trust signs in without a code: keep the devices that hold them locked and in your own hands, choose to trust only a browser that no one else uses, and remove a passkey or forget a browser in Settings when a device is lost, sold or shared.

6. Your data

  • The data collected from your vehicle is yours. The Operator does not sell it and does not share it with others, other than the service providers needed to run the Service as described in the privacy notice and the person you allow to see it (Section 6.1).
  • You can export your data and you can delete it, or your whole account, from within the Service. Deletion and the "clear data" tools are permanent and cannot be undone.
  • An exported backup file contains your complete location history. Once you download it, keeping it safe is your responsibility.
  • You are responsible for keeping your own copies of anything you would not want to lose. See Section 7.1.

6.1 Sharing with someone you allow

  • You may allow one other account to see the vehicles you choose ("Invite to Share"). You create an invitation link and send it yourself; after the other person accepts, you see the email address of their account and approve it, and you then choose the vehicles. The link is personal to that person: keep it private until you send it.
  • The person you allow sees everything the Service shows about those vehicles, including their location history and the names you gave to places and stops. They cannot change, export, import or clear that data, or act on the vehicle.
  • Choosing whom to allow, and which vehicles, is your decision and your responsibility. If other people drive a vehicle you share, you are responsible for telling them, where the law requires that (Section 2).
  • If someone allows you to see their vehicles, that data is theirs. You may look at it for yourself, and you may not copy it out, pass it on, or use it to track a person without the right to do so.
  • Either of you can stop sharing a vehicle or end the connection at any time. The Operator is not responsible for what the person you allowed does with what they saw.

7. What can go wrong, and is not the Operator's responsibility

This section describes, in plain terms, the ways the Service is known to be imperfect. The lists are examples, not limits. You accept all of these risks, and to the fullest extent the law allows the Operator is not responsible for any loss, cost or harm that results from them.

7.1 Data may be lost, incomplete, or never recorded

  • Drives, charges, parked periods or individual readings may not be recorded at all: while the vehicle is asleep or out of coverage, while the maker's systems are unavailable or refuse the connection, while your tokens have expired or been revoked, or while the Service or its database is down, being updated or being moved.
  • Recorded data may later be lost, corrupted, duplicated, merged, split or altered, through hardware or software failure, a hosting provider's action, a mistake by the Operator, a security incident, or a change to how the Service stores or processes data.
  • Backups are made on a best-effort basis. There is no promise that any backup exists, is complete, is recent, or can be restored.
  • An import (of a backup, or of data from another logger) may fail, may be partial, or may change or replace data already in your account. An export may fail or be incomplete.
  • The Service may be discontinued, and all data deleted, at any time (Section 14).

7.2 Figures may be wrong

  • Many figures are calculations or estimates, not measurements: energy used and added, efficiency, charging power and charging cost, idle ("vampire") drain, range, battery capacity and degradation, state of charge on arrival, distances, durations, averages and totals. For example, energy added to the battery may be estimated from the change in state of charge and the battery capacity the vehicle reports, and charging power may be estimated when no measured value is available.
  • Calculations depend on readings supplied by the vehicle maker, which the Operator does not and cannot verify, and which may themselves be wrong, rounded, delayed, missing or reported differently between makers, models and software versions.
  • Where one journey or one charge begins and ends is decided by rules of the Service. It may split one journey into several, join several into one, or miss one entirely, and totals change accordingly.
  • Times, time zones, units and unit conversions, and rounding may be wrong. Figures for the same event may differ from those shown by the vehicle, the maker's app, a charging network, a utility bill or another logger.
  • The Service contains software defects, known and unknown. A figure may change, or disappear, when the software is corrected.

7.3 Information may be out of date or misleading

  • What the Service shows about the vehicle's present state (location, locked or open, plugged in, charging, climate, sleep, state of charge, tire pressure, temperatures, software update status) may be minutes or hours old, even when it is not marked as such. Never assume it describes the vehicle as it is now.
  • Where a vehicle maker does not report a value, the Service may show "unknown", may show a default, or may infer a value. An inferred or default value can be wrong.
  • Addresses, place names, business names and maps come from third-party and community sources, such as OpenStreetMap. A stop may be labelled with the wrong address or the wrong business, and a route drawn on a map may not be the route driven.
  • Vehicle images are generic renderings and may not match your vehicle.
  • Comparisons, trends and summaries are produced automatically and may suggest a conclusion that the underlying data does not support, including about battery health, efficiency or the cost of driving.
  • Mail sent by the Service may be delayed, may not arrive, or may be filtered as spam.

7.4 Do not rely on the Service for anything that matters

The Service is for personal interest and general information only. It is not a safety system, a security or theft-tracking system, a diagnostic tool, or a professional record. Do not rely on it:

  • to decide whether the vehicle is safe, locked, charged, or able to reach a destination;
  • for maintenance, repair, tire or battery decisions;
  • for a warranty, insurance, lemon-law or other claim, or as evidence in any dispute or proceeding;
  • for tax, expense, mileage-reimbursement, billing or accounting records (Section 7.5);
  • to value, buy or sell a vehicle;
  • to locate or monitor a person.

Nothing in the Service is professional advice of any kind. Do not interact with the Service while driving.

7.5 Never use the Service for any purpose in which money could be lost

You must not, under any circumstances, use the Service, or any figure, export, screenshot or other output of it, for any purpose in which its being missing, late, incomplete, wrong or misleading could cause a financial loss of any kind, to you or to anyone else. This applies to every purpose of that kind, whether or not it is listed in this agreement, whether or not it existed or was foreseen when this agreement was written, and whatever the amount involved. The Service is for personal interest only. It is not a mileage log, a financial record or a basis for any decision about money.

Drives may be missing, split, merged or recorded with the wrong distance, time or place, and charging sessions with the wrong energy or cost (Sections 7.1 to 7.3). Without limiting the rule above in any way, the following are examples of what it forbids. Do not use the Service:

  • to claim business mileage, a tax deduction or a tax credit, or to answer a tax authority;
  • to claim reimbursement or an allowance from an employer, a client or anyone else;
  • to bill or charge another person, including for shared use of a vehicle or for electricity;
  • to show compliance with the mileage limit of a lease, a loan, an insurance policy or a warranty;
  • to dispute a charge from a charging provider, a utility or a toll operator;
  • to decide when, where or at what price to charge, to choose an electricity plan, or to budget for energy or travel;
  • to decide whether to buy, sell, lease, repair or insure a vehicle, or at what price;
  • in any business, trade or paid activity, including a fleet, a rental, a delivery or a ride-hailing operation.

If you need information for any purpose on which money depends, obtain it by a means intended for that purpose. If you use the Service for such a purpose anyway, you do so in breach of this agreement and entirely at your own risk, and to the fullest extent permitted by law the Operator is not responsible for any financial loss that results, including any amount you are not paid, any amount you overpay, any lost saving or opportunity, and any tax, penalty, interest or fee.

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

The Service is provided free of charge and is in a pre-release state. There is no service level, no promised availability, no promised response time, and no promise that any problem will be fixed. The Operator may add, change or remove any feature at any time. If the Service is ever offered commercially, that will be under new terms that you will be asked to accept.

9. Acceptable use

You agree not to: connect a vehicle you are not authorised to access; use the Service to track a person without the right to do so; use data another user shared with you for anything other than viewing it yourself; probe, attack, overload or gain unauthorised access to the Service or to another user's data; collect data from the Service by automated means; copy, resell or offer the Service to others; or use it in breach of any law.

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

10. Disclaimer of warranties

THE SERVICE, AND ALL DATA, FIGURES AND INFORMATION IT PROVIDES, 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 AND CONDITIONS, WHETHER EXPRESS, IMPLIED OR STATUTORY, INCLUDING ANY IMPLIED WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, ACCURACY, COMPLETENESS, TIMELINESS, RELIABILITY, AVAILABILITY OR SECURITY, AND ANY WARRANTY ARISING FROM A COURSE OF DEALING OR USAGE OF TRADE.

THE OPERATOR DOES NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, SECURE OR FREE OF ERRORS, THAT DATA WILL BE RECORDED, PRESERVED OR RECOVERABLE, THAT ANY FIGURE OR INFORMATION IS CORRECT OR CURRENT, OR THAT DEFECTS WILL BE CORRECTED. YOU USE THE SERVICE, AND RELY ON ANYTHING IT SHOWS, ENTIRELY AT YOUR OWN RISK.

11. Limitation of liability

TO THE FULLEST EXTENT PERMITTED BY LAW, THE OPERATOR WILL NOT BE LIABLE TO YOU OR TO ANYONE ELSE, UNDER ANY LEGAL THEORY (CONTRACT, TORT INCLUDING NEGLIGENCE, STRICT LIABILITY, STATUTE OR OTHERWISE), FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF DATA, LOSS OF USE, LOSS OF PROFIT, REVENUE, SAVINGS OR GOODWILL, COST OF SUBSTITUTE SERVICES, DAMAGE TO OR REDUCED RANGE, CHARGE OR BATTERY LIFE OF A VEHICLE, ACTION TAKEN BY A VEHICLE MAKER AGAINST YOUR ACCOUNT OR VEHICLE, OR ANY DECISION MADE IN RELIANCE ON THE SERVICE, EVEN IF THE OPERATOR HAS BEEN TOLD THAT SUCH DAMAGE WAS POSSIBLE.

TO THE FULLEST EXTENT PERMITTED BY LAW, THE OPERATOR'S TOTAL LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THE SERVICE OR THIS AGREEMENT WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID THE OPERATOR FOR THE SERVICE IN THE TWELVE MONTHS BEFORE THE CLAIM AROSE AND (B) FIFTY U.S. DOLLARS (US $50).

THE SERVICE IS FREE. THESE LIMITS ARE A FUNDAMENTAL PART OF THE BASIS ON WHICH THE OPERATOR IS WILLING TO OFFER IT AT ALL, AND THEY APPLY EVEN IF A REMEDY FAILS OF ITS ESSENTIAL PURPOSE.

Nothing in this agreement excludes or limits liability that cannot be excluded or limited under the law that applies to you, including liability for fraud, for wilful injury, or for gross negligence, or rights you have as a consumer that cannot be waived. Where a limit in this agreement is not allowed in full, it applies to the greatest extent that is allowed.

12. Disputes with others

Any dispute you have with a vehicle maker, a charging provider, an insurer, another user, or any other third party is between you and them. To the fullest extent permitted by law you release the Operator from all claims and damages, known and unknown, arising out of such a dispute. If you are a California resident you waive California Civil Code Section 1542, which says in substance that a general release does not extend to claims the releasing party does not know or suspect to exist at the time of the release and that would have materially affected the settlement.

13. Your responsibility to the Operator

To the extent the law allows, you will defend the Operator against, and reimburse the Operator for, any third-party claim, and its reasonable costs, arising from: a vehicle you connected without authority; your recording of another person's location or use of a vehicle, including sharing it with someone you allowed; your breach of this agreement; or your breach of any law or of any agreement you have with a vehicle maker.

14. Suspension, termination, and the end of the Service

  • You may stop using the Service and delete your account at any time.
  • The Operator may suspend or close any account, at any time, for any reason or none, including to protect the Service, its other users, or the vehicle-maker accounts the Service depends on.
  • The Operator may discontinue the Service at any time. The Operator intends, where practical, to give notice by email and time to export your data first, but does not promise to, and will not be liable if that turns out not to be possible.
  • Sections 6, 7 and 10 to 18 continue to apply after your use ends.

15. Changes to this agreement

The Operator may change this agreement. Material changes will be announced by email to your account address or by a notice shown when you sign in, before they take effect. If you keep using the Service after a change takes effect, you accept it. If you do not accept it, stop using the Service and delete your account.

16. Users outside the United States

The Service is operated from, and hosted in, the United States, and your data is transferred to, stored and processed there. It is not designed to meet the laws of any other country. If you use it from elsewhere, you do so on your own initiative and are responsible for complying with your local law. If the law of your country of residence gives you consumer rights that cannot be waived by contract, this agreement does not take them away; every other part of it still applies.

17. Governing law and venue

This agreement is governed by the laws of the State of California, United States, without regard to its conflict-of-laws rules. The United Nations Convention on Contracts for the International Sale of Goods does not apply. Any claim must be brought in the state or federal courts located in Riverside County, California, and you and the Operator consent to their jurisdiction; either may instead bring an eligible claim in small-claims court. To the extent the law allows, any claim must be brought within one year after it arose. If you are a consumer living outside the United States, this section does not deprive you of the protection of mandatory provisions of the law of your country, or of any right to sue in its courts, that cannot be waived.

18. General

  • This agreement, together with the privacy notice, is the whole agreement between you and the Operator about the Service.
  • If a part of it is found unenforceable, that part is limited or removed to the smallest extent needed and the rest stays in force.
  • Not enforcing a right is not a waiver of it.
  • You may not transfer this agreement. The Operator may transfer it, including to a company formed to operate the Service, and will tell you if that happens.
  • The Operator is not liable for a failure caused by something outside the Operator's reasonable control, including the acts of vehicle makers, hosting, network and mail providers, and changes to any interface the Service depends on.
  • The English version of this agreement controls over any translation.
