Privacy Policy
Last updated July 2026
This policy explains what the Mainstay website collects, why it collects it, and what happens to information you choose to send us.
Information you give us
The contact form asks for your name and email address. You may also give us a business name and upload a recent utility bill as a PDF or image. Uploads are limited to 4 MB.
If you use the address tool before sending the form, the selected address and your home or business choice are included with the inquiry. We use this information to answer you and prepare an estimate.
What happens to an uploaded bill
The website sends your form submission and any attached bill to Mainstay by email through Resend. This app does not store the submission or bill in a database. Mainstay uses the bill only to prepare your estimate. We use the other details you submit to respond to your inquiry.
Address and location tools
The site calls outside services for specific parts of the address report:
- Google Places receives the text you type into address search when a Google Maps key is configured. Otherwise, Photon by Komoot at photon.komoot.io receives the typed search. These services return possible addresses and coordinates.
- The FCC census area service at geo.fcc.gov receives coordinates so the site can identify a county. This happens after you select an address and when the site resolves the approximate coordinates returned by GeoJS.
- GeoJS at get.geojs.io receives a request when the page loads. It uses the request's IP address to return an approximate location so the site can show a local outage example. The approximate location is not stored by this app.
These providers may receive ordinary technical request information, including an IP address, under their own privacy practices.
Public map data
Map and outage data are static public files served from this site under /atlas and /night. The files are based on EIA, DOE, and other federal grid records. Loading these files does not send your address to those agencies through this app.
Other service providers
Resend processes the contact email and attachment so it can deliver them to Mainstay. The company that hosts this website may process basic request data needed to serve and protect the site. Its platform may set its own cookies.
This site uses Vercel Analytics to count visits and measure how many people check an address or send a bill. It does not use cookies, does not track you across other sites, and does not collect your name, address, or bill. We do not use advertising tools and we do not sell personal information.
How long we keep information
Inquiry emails are kept only as long as reasonably needed to prepare an estimate, follow up with you, and meet legal or security obligations.
Your choices
You can ask what information we have about you or ask us to delete it by emailing hello@mainstay.energy. We will take reasonable steps to honor the request for records we control, subject to any information we must keep for legal or security reasons.
Children's information
This service is not intended for children, and we do not knowingly collect personal information from children. If you believe a child has sent us personal information, email hello@mainstay.energy.
Security
We use reasonable technical and organizational measures to protect the information we receive. No website, email system, or internet transmission is completely secure, so we cannot guarantee absolute security. Please do not upload a bill if you are not comfortable sending it by email.
