This policy should be reviewed before launch and again before advertising is enabled.
What we don't collect
TravelCostKit is completely free to use, with no accounts, sign-ups, subscriptions or payments. Calculator maths runs in your browser. Names and expense descriptions are never sent for AI explanations.
Optional AI explanations
AI explanations are temporarily disabled for launch. Calculator results do not require AI and remain available.
While AI explanations are disabled, the explanation buttons are hidden and requests to the explanation service are rejected without contacting an AI model. No automatic AI generation takes place.
If we re-enable this optional feature, choosing “Explain this result” would send an unnamed numeric summary (such as totals, currency, group size and nights) through our server to Lovable AI. We would not store this summary in our database; hosting and AI services could retain service logs under their own policies. The database is reserved for request counts and service availability information, not calculator inputs. We will review this policy before re-enabling AI. Calculator numbers remain the source of truth.
Data stored on your device
To keep your work between visits, calculators save your inputs in your browser's local storage. This stays on your device, and you can delete it at any time by clearing your browser's site data. It is not used for tracking.
Shareable links
The trip expense splitter can create links containing names, descriptions and expenses. The information is encoded, not encrypted. It sits after #, which browsers do not include in ordinary page requests to web servers. Anyone with the complete link can read it. Links are snapshots and cannot be revoked or remotely deleted. Browser history, messaging services and recipients may retain copies. Avoid sensitive personal information and share only with people you trust.
Local trip files and imports
You can export and import trip JSON files on your device without uploading them to our server. These files may contain names, descriptions and expenses and are not encrypted; store and share them carefully. Shared links are limited to 2,000 characters and files to 1 MB. Incoming data is validated, and a different incoming trip asks for confirmation before replacing a valid saved trip. You can export your current trip first or cancel. Clearing your device's saved trip does not remove links or files retained elsewhere.
Server logs
Like any website, our hosting provider may automatically record technical information such as IP address, browser type and pages requested, for security and reliability.
Advertising (future)
We do not currently show ads. If we add advertising such as Google AdSense, third-party vendors including Google may use cookies to serve ads based on your visits to this and other sites. Before that happens we will update this policy and, where required (for example in the UK and EEA), ask for your consent through a certified consent management tool. You will be able to opt out of personalised advertising.
Children
The site is intended for a general audience and does not knowingly collect personal information from children.
