MangoStack is an early-stage concept in validation. This site is a single page with one form on it. This policy covers that form and the anonymous visit counts described below, and nothing else — there is no product account to sign up for yet.
What we collect
What you type into the early-access form:
- Your name
- Your organisation
- Your work email address
- Your phone number, if you choose to give one
- Whether you want to talk, try it first, or both
- Anything you write in the optional notes field
We also count visits, so we know how many people the site reaches. Each page view records:
- The page you opened and the time
- The site that linked you here, if any
- Your approximate location — country, region and city
- Your browser, operating system and device type
These counts are anonymous. They are not linked to your name, your IP address or anything you type into the form, and we only see them as totals.
The site sets no cookies and does not track you across other sites.
Why we collect it
To reply to you, and to understand how NGO teams actually run projects so we build the right thing. That is the whole purpose. We will not add you to a marketing list, sell your details, or pass them to anyone else for their own use.
Where it goes
Submissions are delivered to us through Formspree, a third-party form service, and land in our email inbox. Formspree processes the submission on our behalf and holds a copy on their servers; their privacy policy governs what they do with it.
Visit counts are collected by Vercel Web Analytics, run by Vercel, the company that hosts this site. It uses no cookies. To tell one visitor from another it makes a short-lived identifier from the incoming request, which is discarded after 24 hours.
This site also loads fonts from Google Fonts, which means Google receives your IP address and browser details when the page loads. We do not send Google anything else.
How long we keep it
Only as long as it is useful for the conversation you started. Email us and we will delete it.
Changes
This page always carries the current version of this policy. If it changes, the date at the top changes with it.
