Common Questions
Pro removes the caps: unlimited saved protocols (free stops at 3), full dose history (free keeps 30 days), PDF export for lab-ready printouts, and advanced tools like sequential draw-to mapping for multi-peptide stacks. Free keeps the full calculator forever.
Yes, one click from your account. No phone call, no email back-and-forth. You keep Pro until the end of the period you already paid for, then it stops billing and your account reverts to Free limits immediately. Nothing is deleted. See the next question.
ASCEND is a calculation tool, not a medical records system. It does not store patient-identifiable data. Protocols you save are attached to your account only. For clinical use, the PDF export is designed to be printed and attached to patient files at your discretion.
Nothing is deleted, ever. Your account reverts to Free limits right away (3 protocols visible for new saves, 30 days of history shown), but every protocol and dose you already logged stays in your account. You keep viewing and using everything you had before cancelling, you just can't add past those caps. Resubscribe and the full history and unlimited protocols come back instantly, nothing to restore.
Yes, but on a separate plan. API access, embeddable widgets, and white-label tooling live on the developer side. See the API page or contact us directly.
