Effective September 26, 2026
Mainstay Web is a service of Caminus Group LLC (“Mainstay”, “we”, “us”). We design, host and look after websites for small businesses. This policy covers mainstayweb.co, our client portal at portal.mainstayweb.co, and the business websites we host for our clients. If you have a question, email support@mainstayweb.co.
What we collect
| When you contact us | Your name, business name, email address, and anything you choose to add: phone number, current website and your message. |
|---|---|
| If you are a client | Your sign-in email, the business details and content for your website, update requests and any files you upload, your email preferences, and a record of changes we make. Billing details (name, billing address, and optional tax ID) are collected by Stripe. |
| Payments | Card and bank details are entered on pages run by Stripe and stay with Stripe. We never see or store full card numbers. We keep Stripe’s customer and subscription references, and invoice and payment status. |
| Businesses we research | To find businesses we could help, we review publicly available business information such as a business’s name, website, public phone number, service area and public listings. We use it only to decide whether to offer our services and to contact the business. |
| Contact forms on client websites | If a client’s website has a contact form, the details you enter are passed to that business so they can reply to you. |
| Technical information | Like most websites, our hosting provider records technical data such as IP addresses and browser type to deliver pages and keep them secure. To limit spam we use a one-way scrambled form of your IP address for a short time. The client portal uses essential cookies to keep you signed in. We do not use advertising or cross-site tracking cookies. |
How we use it
- To reply to you and discuss the website you need.
- To build, host, update, back up, monitor and support our clients’ websites.
- To handle billing, send receipts, reminders and service messages you have chosen to get.
- To keep our services secure and prevent spam and abuse.
- To contact businesses about our services, and to stop contacting any business that asks us not to.
We do not sell personal information, and we do not share it for advertising.
AI tools
We use AI tools to help us work faster. When you contact us, Cloudflare Workers AI writes a short private summary of your message for our team. When a client asks for a website change, AI models (including Anthropic’s Claude) help prepare the change, which a person reviews before it is published. These tools process the information only to do that task. They never send messages to you on our behalf.
Who helps us
We share information only with service providers that help us run Mainstay, and only what they need:
- Cloudflare: website hosting, databases, file storage, backups, security and Workers AI.
- Stripe: payments, invoices and the billing portal.
- Supabase: secure sign-in for the client portal.
- Resend: sending our emails, such as sign-in links, receipts and notifications.
- AgentMail: a copy of messages sent through our contact form, for our team’s records.
- Anthropic: AI assistance when preparing website changes.
- Google Fonts: the typefaces on mainstayweb.co, which your browser loads from Google.
We may also share information if the law requires it, to protect our rights or the safety of others, or as part of a sale or transfer of our business.
How long we keep it
- Contact form messages sent to us: as long as we need them to reply and for our business records, unless you ask us to delete them.
- Client account information: while you are a client, and for a reasonable period afterwards for accounting, legal and dispute purposes.
- Messages from contact forms on client websites: deleted from our systems 30 days after they are delivered to the business.
- Backups: daily copies are kept for about 35 days and monthly copies for about 13 months, then deleted.
Your choices
- Email support@mainstayweb.co to see, correct or delete the personal information we hold about you. We may keep what we must for legal, tax or security reasons.
- Clients can change email preferences in the portal. Service messages about your account and billing still go out.
- If we contacted your business and you would rather we did not, tell us and we will stop.
Security
Information travels over encrypted connections. Access to client data is limited to people and systems that need it, and sign-in uses one-time links rather than passwords. No system is perfectly secure, so please don’t send payment details or other sensitive information through contact forms.
Children
Our services are for businesses and are not directed to children under 13. We do not knowingly collect their information.
Changes
If we change this policy, we will update the date at the top of this page. For significant changes that affect clients, we will also let clients know by email.
