Support Papertrek
Papertrek is built and run by one researcher. It is free, and it is meant to stay free for anyone who cannot or does not want to pay. If it saves you time and you can spare something, a tip is welcome. Your account is the same either way.
Why it is free
Every feature is open to everyone: unlimited manuscripts, reminders, the calendar feed, auto-sync, analytics, your public page. Research tools should not sort people by budget, and the server costs the same whether ten or a thousand people use it. What you give is a tip for the project, not a payment for a service: it buys nothing, and not giving hides nothing.
What support pays for
The server and its backups, the domain, the mail that carries your reminders, keeping the Crossref and ORCID imports working as those services change, and the evenings that go into the features people write in about.
How to support
Any amount is welcome, once or whenever you like. The same page also supports Classperiment, a sister project, so if you want to say which one you mean, a word in the message is enough.
Ko-fi and PayPal run under their own terms and privacy policies. Papertrek stores nothing about it: no name, no amount, no account. Supporting the project is never connected to what you see or do in the app.
Other ways to help
Tell a colleague who is juggling three manuscripts. Send a wish or a bug report from inside the app or through the contact page. Both have shaped most of what Papertrek does today.
