Privacy policy
Last updated 15 October 2026Best Newsletter Ads (“we”) is run by [NEED: legal entity name], [NEED: registered address]. This policy covers bestnewsletterads.com, our emails and our MCP server. Questions or requests: [NEED: privacy contact email].
What we collect
| Data | Why |
|---|---|
| Your email address | To log you in (a one-time code or link) and, if you keep them on, to send the Monday digest and watchlist alerts. |
| Your name or company, and your newsletter’s URL (or what you plan to write about) | To match you to your newsletter and category, so the digest and alerts show ads that matter to you. |
| What you do on the site: newsletters you watch or visit, searches, newsletters you request, MCP tool calls | To show what’s new since your last visit, run your watchlist and requests, rate-limit the MCP, and understand which features help. |
| A random browser id and a hashed IP address | To count the 3 free ad views and stop them being abused. We store a one-way hash of your IP, not the IP itself. |
We don’t sell your data, we never contact your subscribers, and we don’t tell anyone which newsletters you looked at.
The ads in the library
Ads come from the public Meta Ad Library. We store the creative, copy, landing page and the weeks each ad was seen running. We don’t know or estimate ad spend.
Cookies
- Essential: your login session, whether you’ve finished sign-up, and the browser id behind free views.
- There are no analytics, advertising or cross-site trackers.
Who processes data for us
- Vercel (hosting), Supabase (database and sign-in), Cloudflare R2 (image storage)
- Resend (sending email)
[NEED: confirm regions and data processing agreements for each provider.]
Legal basis (UK / EU)
We provide the service you signed up for (contract), send the digest and alerts with your consent (you can turn them off in one click), and keep the site secure and improve it (legitimate interests).
How long we keep it
While your account is open. When you ask us to delete your account we delete your profile, watchlist, requests and API keys within 30 days; email delivery logs may be kept for up to 12 months to prove unsubscribes were honoured.
Your rights
You can access, correct, export or delete your data, object to processing, and complain to your data protection authority. Change email preferences on your account page, or use the unsubscribe link in any email. For anything else, email [NEED: privacy contact email].
