FAQ

Answers to things people actually ask.

Can I export all my pages?

Yes. Settings → Export All Pastes downloads everything as a single ZIP. No lock-in.

How long do pages last?

Free: 60-day maximum, 7-day grace period to restore. Pro & Studio: leave it blank and it stays forever — or set any date you want.

Can I run JavaScript?

Yes. Pages are served with a CSP sandbox — your scripts run, but they can't break out to other pages or the host.

Can I use my own domain?

Custom domains aren't supported, but Pro and Studio plans get custom URLs: pastml.com/c/your-name.

What formats are supported?

HTML (text/html) and Markdown (text/markdown). Markdown is auto-converted to a dark-themed page.

Who can see my pages?

Anyone with the URL. There are no private pages, but Studio users can add password protection to any paste.

Is payment secure?

Yes. All payments are processed by Stripe. PastML never sees or stores your card details.

How do I upgrade or downgrade?

Free users: click Upgrade to Pro or Studio on the Settings page. Paid users: go to Settings → Manage Billing to switch plans via Stripe.

Can I get a refund?

If you're unsatisfied with a paid plan, request a full refund within 7 days of the charge. Only the most recent charge is refundable — prior periods are not. Contact [email protected].

How do I cancel?

Settings → Manage Billing → cancel inside the Stripe portal. Your plan stays active until the end of the billing period, then reverts to Free — no ongoing charges.
