Everything people ask, answered plainly.

Not selling your data is a policy. Not holding your data is an architecture. Protocol Her is built the second way, which is why the privacy policy is short.

• The calculator converts, it does not recommend. Give it the mg on your vial, the mL of water you added, and the amount you want to measure, and it returns mL and U-100 syringe units with every step of the arithmetic printed so you can check it by hand.
• You enter every number. The app never fills in a vial size, a water volume, or an amount on your behalf, because the only figure that is true is the one printed on the vial in front of you.
• Reference ranges are sourced or absent. Where a commonly reported range appears, it traces to FDA labeling or a published human trial and is shown as a reference. Compounds with no traceable human source display no range at all rather than a guess.
• Classification is always on. Every compound shows whether it is FDA-approved, investigational, or primarily preclinical research, and everything that is not FDA-approved carries a standing warning. That label never softens based on anything you enter.
• Weeks are counted, never prescribed. Your progress through a protocol is derived from what you actually logged. The app never runs ahead of you with a plan.

Unit conversion is arithmetic. What to take, how often, and whether to take it at all are medical decisions that belong with a licensed clinician who knows your history.

• Every answer is pre-written. Her Bot assembles its replies from a reviewed set of sentences and from your own records. There is no AI model generating text, so it cannot invent a fact, a number, or a source.
• It runs on your iPhone. No server, no internet request, nothing sent anywhere to be answered. Her Bot works in airplane mode, and your logs never leave the phone to reach it.
• Your conversation stays with your data. Chat history sits in the same encrypted database on your phone as the rest of your logs. Delete a single message, or clear the whole conversation, whenever you like. Clearing the chat touches nothing else.
• It gives no dosing, medical, or symptom advice. Ask it what to take, whether two compounds interact, or what a symptom means, and it says plainly that it cannot help with that one and points you back to your clinician, or to emergency services if the question sounds urgent.
• Included with Pro, with no question limit. Her Bot comes with Protocol Her Pro, and there is no cap on how much you ask it.

Most assistants in health apps are a language model with your data pointed at it. This one is the opposite arrangement: a fixed set of answers that never leaves the device, which is the only version of the feature that fits an app holding no copy of your records.

The catalog is curated, so free-text custom compounds cannot be added to a tracked protocol. A name the app does not recognize would produce no schedule, no unit, and no classification, which is worse than an honest no. Vial inventory is the one exception: a custom compound name can be entered there and tracked as a vial.

Prices are set in US dollars and can differ by App Store region. Pro renews automatically until cancelled, and you manage or cancel it in your Apple account settings rather than in the app.

Since no cloud copy of your logs exists, these exports are also how you make your own backups. Take one before you switch phones.
