AGENT APP · BUY CAR

Find the one.

Real car listings, saved links, and a comparison grid that makes the details easier to see.

Support

Search by make and model. Save the cars you like, add private notes, and compare up to four cars. Save any public HTTPS listing link even when a source cannot be read automatically.

For help, email jonah@3decisions.ai. Include the app version and the listing source. Do not include passwords or private financial documents.

Inventory coverage

Buy Car reads public pages from supported sources. Results can be limited to the first returned page and do not represent the entire market. Some sources restrict automatic access. Each search shows source coverage. Equipment not supplied by a source is unknown, not absent.

Availability is the source's status at its last check, not a guarantee. Prices can exclude taxes and fees. Confirm details with the seller before buying.

Daily checks

Opt in on each saved car. Supported public listing links are checked daily while the service is running. Your phone retrieves updates when you open the app or refresh. iOS background updates are best effort. Confirmed removed listings are archived, preserving your notes. Failed checks remain unverified.

Scheduled links expire after 30 days. This beta runs on existing infrastructure and has no uptime guarantee.

Privacy policy

Effective September 11, 2026. Buy Car is operated by JCG Creations IV LLC under Agent App.

Your saved cars, notes and comparison selections are stored on your device. Searches send make, model and optional ZIP code to our inventory service. Reading a listing sends its public URL. Enabling daily checks stores that URL for up to 30 days. Search and page responses are cached for operation. Infrastructure providers process network addresses to deliver and protect the service.

We do not send notes, contacts or account credentials. There is no advertising, analytics SDK, account, payment or hosted AI. Listing images load from their original publisher, which receives a network request. Opening source links is subject to those sites' policies.

You can delete saved cars in the app. Backups are created only when you request them and are shared using destinations you choose. For questions or a service-data deletion request, contact jonah@3decisions.ai.
