Privacy Policy
Last updated: June 27, 2026
This Privacy Policy explains how Sidetrack Services, LLC, doing business as FlintSpan ("FlintSpan," "we," "us") handles personal information in connection with the FlintSpan platform and websites (the "Service"). FlintSpan provides software that lets rental businesses ("Clients") run a branded website and reservation system for the people who rent from them ("Renters").
Our two roles
- For our Clients' and visitors' data (account, billing, marketing-site visitors), FlintSpan is the controller.
- For Renter personal data processed through a Client's site (reservations, uploaded documents, signatures, contact details), the Client is the controller and FlintSpan is the processor / service provider, acting on the Client's instructions. If you are a Renter, direct privacy requests to the rental business you booked with; we assist them in responding.
Information we handle
- Client & account: business name, contact, login, plan, and billing details.
- Renter data (on a Client's behalf): name and contact info, reservation details, and - where a Client enables it - uploaded identity/insurance documents, e-signature data, and delivery addresses.
- Payments: handled by payment processors; we do not store full card numbers.
- Usage & device: log data, IP, and similar technical information to operate and secure the Service.
- Communications: messages you send us (e.g., support).
How we use information
To provide, secure, support, and improve the Service; to process subscriptions and billing; to send service communications; and to comply with law. We do not use Renter data for our own marketing.
We do not sell or share your personal information
FlintSpan does not sell, rent, trade, redistribute, or share personal information. We disclose it only to the service providers (sub-processors) listed below strictly to operate the Service on our or a Client's behalf, and where required by law (e.g., a valid legal request) or to protect rights and safety. We do not share personal information for cross-context behavioral advertising.
Service providers & integrations we use
We rely on the following providers to run the Service. Clients may also connect their own integrations. These are independent third parties: FlintSpan does not control how they handle data, and their practices are governed by their own privacy policies - please review them.
- Amazon Web Services (AWS) - hosting, storage, database, and email delivery.
- Stripe and/or Square - payment processing (Client-connected).
- Twilio and/or QUO (OpenPhone) - SMS messaging (Client-connected).
- Google Maps Platform - address lookup and delivery-distance calculation.
- Google Analytics - only when a Client enables it for their own site.
- Anthropic - AI used for optional document verification (OCR) and the assistant feature (see below).
- igloohome - smart-lock access codes (Client-connected).
- Google / Microsoft Calendar - calendar sync (Client-connected).
Where an integration is one a Client connects with their own account, that Client's relationship with the provider - and the provider's own terms and privacy policy - govern that data.
AI document verification (OCR)
If a Client turns on identity/insurance verification, the uploaded document image is sent to our AI provider (Anthropic) to read and validate fields (such as name, expiration, and license class). We store only the extracted fields and the verification result - not the image at the AI provider - and our AI provider does not use the data to train its models. A failed or unclear check is flagged for the rental business to review; it does not by itself reject a reservation.
Google Calendar (calendar sync)
If a Client connects Google Calendar, FlintSpan asks Google for permission to see the list of calendars in that Google Account (so the Client can choose which calendar to sync) and to create, update, and delete events on the chosen calendar. We use this access only to place each reservation on the Client's calendar and keep those events in sync - we do not read the Client's other events or use the access for any other purpose. A Client can disconnect at any time, which revokes our access to their Google data.
Limited Use. FlintSpan's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. Specifically: we do not use Google user data for advertising; we do not sell it; we do not transfer it to others except as needed to provide and improve the calendar-sync feature, with your consent, or as required by law; and we do not use it to develop, train, or improve generalized AI/ML models. No humans read this data except with your consent, for security or to comply with law, or as strictly necessary to operate or troubleshoot the feature.
Text messaging (SMS)
FlintSpan operates a messaging service that rental businesses use to send service and transactional text messages (booking confirmations, pickup/return and "ready" notices, reminders, payment and agreement links, and account notices) to renters and their own staff. You consent to these messages when you provide your mobile number while booking, creating an account, or opting in on a FlintSpan-powered site. Message frequency varies with your activity, and message and data rates may apply. You can reply STOP to opt out at any time or reply HELP for help. We do not sell or share mobile phone numbers or SMS opt-in data with third parties for their marketing. Full details are in our Messaging Policy.
Cookies & sessions
We use strictly necessary cookies for login/session security (httpOnly, secure cookies - we do not put auth tokens in local storage) and CSRF protection. We do not use third-party advertising cookies. Analytics cookies appear only on a Client site if that Client enables their own analytics.
Security
We protect data with encryption in transit and at rest, per-tenant key isolation, and envelope encryption (managed keys) for the most sensitive documents such as driver's licenses, plus access controls, tenant isolation enforced in the database, and audited access. No method is perfectly secure, but we work to protect your information.
Data retention
We keep account data while an account is active and for a limited period afterward, then delete or de-identify it. A Client may export or request deletion of data; on cancellation, data moves to archival storage and is purged on a schedule (and sooner on a valid request), subject to legal retention needs.
Your privacy rights
Depending on where you live (for example, under the California Consumer Privacy Act / CPRA), you may have the right to know, access, correct, delete, and limit certain uses of your personal information, and to not be discriminated against for exercising those rights. Because we do not sell or share personal information, there is no sale to opt out of - see Do Not Sell or Share My Personal Information for that notice and how we honor the Global Privacy Control (GPC) signal. To exercise rights as a Client or marketing-site visitor, email privacy@flintspan.com. If you are a Renter, contact the rental business you booked with (the controller); we will help them respond.
Children
The Service is for businesses and adults; it is not directed to children, and we do not knowingly collect data from anyone under 18.
International
FlintSpan operates in the United States; if you access the Service from elsewhere, you understand your information is processed in the U.S.
Changes
We may update this policy; we will post changes here with a new date and, where appropriate, additional notice.
