your numbers stay yours

The short version

lapcost runs entirely in your browser. We have no accounts, no login, no newsletter, no cookies, no analytics and no advertising. Your calculator inputs are saved on your own device and are never transmitted to us. The only personal data that exists at all is the standard technical log our hosting provider keeps to run the server. That is the whole story; the sections below spell it out properly.

1 · Who operates this site

lapcost.com is operated by drivenerve, an independent studio established in the European Union, as part of the drivenerve family of free driving tools. Contact for anything in this policy, including data protection requests: hello@drivenerve.com. Full business details are available on request by email and will be published on this page before any commercial feature goes live.

2 · What happens on your device

• Calculator data. Your inputs (costs, lap times, vehicle mode, currency, season length) are stored in your browser's localStorage under the key lapcost-v2 so the tool remembers your setup. This data never leaves your device. Clear it any time via your browser's site-data settings, or by using private browsing, and it is gone.
• Offline cache. A service worker stores copies of this site's files on your device so the calculator works without signal. It caches our files only, no personal data.
• Share links. When you copy a share link or summary, your numbers are encoded into that link by your own action. Anyone you send it to can read those numbers, so share links the way you would share the numbers themselves.
• Cost cards. The downloadable image is rendered in your browser and saved by you. We never see it.

This storage is strictly necessary for a feature you actively use (saving your own inputs), which is why no consent banner is required for it under EU ePrivacy rules. We use no cookies of any kind.

3 · What reaches a server

When you load the site, our hosting provider's web server processes your IP address, browser user-agent and the pages requested, and keeps short-lived technical access logs. This is standard for virtually every website; the legal basis is legitimate interest in operating and securing the service (GDPR Art. 6(1)(f)). We do not use these logs to identify or profile anyone, and we add no analytics on top of them. All site assets, including fonts, are served from lapcost.com itself: the page makes no third-party requests.

4 · What we do not do

• No accounts, passwords or newsletter, so no email addresses are collected.
• No analytics or measurement scripts, first-party or third-party.
• No advertising, ad networks or tracking pixels.
• No sale or sharing of personal information, in the CCPA sense or any other.
• No profiling, no automated decision-making, no cross-site anything.

5 · Planned features, stated honestly

None of the following is active today. If and when any of them launches, this policy will be updated first and the date above will change.

• Analytics. If added, it will be a cookieless, aggregate page-view counter (such as Cloudflare Web Analytics) that does not identify visitors and sets nothing on your device.
• Affiliate and partner links. If added, they will be clearly labelled as partner links where they appear. Clicking one takes you to the partner's site, which has its own privacy policy; we would receive aggregate commission reporting, not your identity.
• Newsletter. If added, it will be double opt-in, used only for what you signed up for, with a working unsubscribe in every message.

6 · Your rights

If you are in the EU/EEA or UK, you have the GDPR rights of access, rectification, erasure, restriction, portability and objection, and the right to complain to your supervisory authority. Because we hold no personal data about you beyond transient server logs, most requests resolve to "there is nothing on file", but we will answer every one: hello@drivenerve.com.

Residents of California and other US states with privacy laws: we do not collect, sell or share personal information as defined by those laws, and we honour the rights they grant. The same applies in substance under Canada's PIPEDA, the Australian Privacy Act and the New Zealand Privacy Act: there is no collected personal information to access or correct, and you may contact us about any concern.

7 · Children, changes, contact

The site is not directed at children and collects no data from anyone, children included. If this policy changes, the new version appears here with a new date; material changes will be flagged plainly at the top. Questions: hello@drivenerve.com.
