Privacy policy
Last updated November 14, 2026
Leftwarm makes software that helps home improvement companies follow up with people who asked them about a project. This policy explains what we collect, how we use it and the choices you have.
Two kinds of information
About our customers and website visitors. When you use this website, fill in one of our forms or sign up for Leftwarm, we decide how that information is used, as this policy describes.
About homeowners, on a contractor's behalf. When a contractor uses Leftwarm, they give us details about people who contacted them. We handle that information for the contractor, under our agreement with them, and only to follow up for that contractor. Each contractor's information is kept apart from every other contractor's.
What we collect
From this website
- What you type into our forms: your email address and, if you give them, your name, company, phone number, a description of your business and your message, plus the page you sent it from.
- A scrambled (hashed) form of your IP address, used only to stop our forms being flooded with spam. We don't keep the address itself.
- Our pages load fonts from Google Fonts, so Google receives your browser's IP address when you visit. We don't use advertising trackers.
From contractors who use Leftwarm
- Details about the people who sign in: name, email address and role.
- Business details needed to register a business texting number with phone carriers, such as the legal name, address, tax ID and a contact person.
- A cookie that keeps you signed in to the Leftwarm app. We don't use cookies for advertising.
About homeowners, on a contractor's behalf
- Name, mobile number and email address.
- What they asked about and roughly when, and how and when they agreed to be contacted.
- Text messages sent and received, appointment times, and whether visits happened.
- Requests to stop texts.
- Checks on the phone number: whether it's a mobile number, whether it's on the national Do Not Call registry, and whether it has been reassigned to someone new.
How we use it
- To provide Leftwarm: text people on a contractor's behalf, book visits, send confirmations and reminders, and show contractors their conversations, bookings and billing.
- To follow the rules for business texting: checking consent, honoring opt-outs, keeping to allowed hours and keeping the records that show it.
- To answer your requests and run our business: support, billing, security, and preventing fraud and spam.
We don't sell personal information, and we don't use homeowners' information to market our own services.
Text messages
We share mobile numbers only with the service providers that deliver texts for us, and only for that purpose. We never share mobile numbers, text messaging opt-in data or consent with anyone else, including affiliates, for marketing or promotional purposes.
Anyone who gets a text through Leftwarm can reply STOP to stop texts from that business, and HELP for help. See our texting terms.
Who we share it with
- Service providers that run Leftwarm for us, under contracts that limit them to providing their service: hosting and databases in the United States (Render), text messaging (Twilio), email (Postmark), and an AI model provider (Anthropic) that drafts replies from a conversation and the contractor's approved answers.
- The contractor that a homeowner's information belongs to.
- Others when the law requires it, to protect people's rights and safety, or as part of a merger or sale of our business, with the same protections.
How long we keep it
We keep information as long as we need it to provide Leftwarm and meet our obligations. When a contractor stops using Leftwarm, we return or delete their homeowners' information, except records we must keep to show that texts followed the law, such as consent and opt-out records, which we keep for up to five years. Requests sent through this website are kept for up to two years.
How we protect it
Information is encrypted in transit, secrets such as access keys are stored encrypted, each contractor's information is walled off from every other contractor's, and access is limited and logged. No system is perfectly secure, so if something goes wrong we'll tell the people affected as the law requires.
Your choices
- Customers and website visitors can ask to see, correct or delete their information by emailing hello@leftwarm.com.
- Homeowners can reply STOP to any text, and can ask the contractor who has their information, or us, to see, correct or delete it. We'll pass requests we get to the contractor.
- Depending on where you live, state privacy laws may give you more rights. We'll respond as those laws require, and we won't treat you differently for using them.
Children
Leftwarm isn't meant for children under 13, and we don't knowingly collect their information.
Changes
We'll post any changes here with a new date, and tell our customers about significant ones before they take effect.
