PeptOnyx Calculator Privacy Policy

Last updated: 15 August 2026

Sound Grounds Limited ("SoundGrounds", "we", "us", "our") is a New Zealand company and the publisher of PeptOnyx Calculator, a dosing and reconstitution measurement app. This policy explains what information PeptOnyx Calculator collects, how we use it, and the choices you have. It is written to comply with the New Zealand Privacy Act 2020.

Information we collect

PeptOnyx Calculator does not require an account or any sign-in, and does not ask you for your name, email address, or any other personal details.

Calculation, vial, and dose history information, stored only on your device

• Any vials you choose to save (medication name, vial amount, diluent volume, reconstitution date, remaining amount)
• Your dose calculation and logging history

This information is stored locally on your device and is never sent to us or to any server we operate. We have no way to see it, and it is deleted if you uninstall the app.

We do not collect location data, contacts, photos, browsing history, advertising identifiers, or any information beyond what you choose to enter into the calculator itself. PeptOnyx Calculator does not show ads and does not use any analytics or tracking software.

How we use information

We don't. PeptOnyx Calculator has no server, and nothing you enter is transmitted anywhere -- there is nothing for us to use, because we never receive it.

Who we share information with

No one. PeptOnyx Calculator does not integrate with any third-party advertising, analytics, or data services. We do not sell your information, because we never have access to it in the first place.

Data retention

Your saved vials and dose history live only on your device for as long as you keep the app installed. Uninstalling PeptOnyx Calculator permanently deletes this information, since we hold no copy of it ourselves.

Children's privacy

PeptOnyx Calculator does not knowingly collect personal information from children, since it does not collect any personal information at all -- everything described in this policy is stored solely on-device.

International users

PeptOnyx Calculator is available worldwide. This policy is written to comply with New Zealand law, since Sound Grounds Limited is a New Zealand company. If you are located elsewhere, additional local laws may also apply to how your information is handled.

Changes to this policy

We may update this policy from time to time. The "Last updated" date at the top of this page reflects the most recent revision.
