Privacy Policy

StackTie is a trading name of MPM Solutions LLC, which is responsible for the information described here. This policy covers this website and our product development subscription. Our HubSpot apps have their own policies, linked from each app’s listing.

Information you give us. Your name, email, company and anything you tell us about your product, whether by email, live chat, a form on the website, a booked call, or your project board.

Billing information. When you subscribe, Stripe collects your payment details. We never see or store your full card number. We receive your name, email, billing address and subscription status from Stripe.

Project access. To do the work, you may give us access to your code repository, hosting, and other tools. We use that access only for your requests.

Website usage. Pages visited, clicks, device and browser type, and approximate location, collected through cookies and similar technologies (see section 6).

• To provide the subscription: take requests, build, and deliver work.
• To bill you, handle refunds, and keep accounting records.
• To reply to you and send messages about your subscription.
• To understand how the website is used and improve it.
• To measure our advertising, such as whether an ad led to a signup.
• To keep the service secure and meet legal obligations.

We do not sell your personal information. We share it only with the services we use to run the business, each of which processes it on our behalf:

• Stripe, for payments and subscriptions.
• PostHog, for website analytics.
• Google (Tag Manager and Ads), for measuring advertising.
• Crisp, for the live chat on the website.
• Cal.com, if you book a call.
• Resend, which delivers messages sent through forms on the website.
• Vercel, which hosts this website.
• Trello and Slack, where we manage and discuss your requests.

We may also share information if the law requires it, or with a buyer if the business is ever sold, in which case this policy continues to apply.

Your code, data and credentials are used only to do your requests. We do not copy your code into other clients’ projects or use it to train anything. When your subscription ends, we remove our access and delete credentials you shared with us.

The website uses cookies and similar technologies for analytics (PostHog), advertising measurement (Google), and live chat (Crisp). You can block or delete cookies in your browser settings; the site still works without them, although chat may not.

We keep client and billing records for as long as you are a client and afterwards for as long as tax and accounting law requires. Website analytics are kept in aggregate. You can ask us to delete your information sooner where the law allows.

You can ask us to show you the information we hold about you, correct it, delete it, or send you a copy. You can also object to marketing at any time. Depending on where you live (for example the EU, UK or California), you may have further rights under local law, including the right to complain to a data protection authority.

To make a request, email michael@stacktie.com. We reply within 30 days.

We use reputable providers, encrypted connections, and access limited to the people doing your work. No system is perfectly secure, but if we ever learn of a breach affecting your information we will tell you promptly.

We and some of our providers are based in the United States, so your information may be processed there. Where required, those providers use recognised safeguards such as standard contractual clauses.

The service is for businesses and is not directed at anyone under 18. We do not knowingly collect information from children.

If we change this policy we will update the date above, and for significant changes we will email active clients.
