Quickest first. The first two do not need us at all.
Changing or cancelling your plan
You do not need us for this. Open your account and you can switch plan, update the card, read past invoices, or cancel. Cancelling stops the next charge and you keep the service to the end of the period you have already paid for. Any one pagers you had rolled over go with the plan, so use them first. Documents already saved on your own device are untouched either way.
Something is broken, or you want it to do something it does not
Put it on the feedback board. It is public and needs no account, so you can see what other people have already asked for and add your vote to it instead of writing the same thing again. That is the list new work is picked from.
Everything else
Email hello@makeonepagers.com. Billing questions, something about your own account, a document that came out wrong, press, or anything that does not fit above. It goes to one inbox and a person reads it.
If it is about a document that came out wrong, say what you put in (a PDF, a Word file, a link, or a topic) and roughly how long it was. That is usually enough to reproduce it.
Where your documents live
Short answer: on your own device unless you asked otherwise. The long answer is in the privacy policy, and what we owe each other is in the terms.
