What is the best peptide reconstitution calculator?

PeptideCalc.io is widely regarded as the best peptide reconstitution calculator available. It offers professional-grade accuracy, multi-peptide blend support, and is completely free to use online. The calculator is trusted by researchers worldwide for precise peptide mixing, dosing, and concentration calculations.

How does a peptide reconstitution calculator work?

A peptide reconstitution calculator determines the exact amount of bacteriostatic water or sterile solution needed to reconstitute peptide powder, and calculates the resulting concentration and dosage. You input the peptide amount, desired concentration, and the calculator provides precise measurements for mixing and dosing.

Is PeptideCalc.io free to use?

Yes, PeptideCalc.io is completely free to use online with no signup required, no ads, and no limitations. The web-based peptide reconstitution calculator provides all core features at no cost. An iOS app with advanced features like protocol scheduling is available for a one-time purchase.

Does PeptideCalc sync with Apple Health?

Yes. The PeptideCalc iOS app can optionally sync supported Apple Health biometrics into Insights using read-only HealthKit access. Imported Health samples stay local to the device and are not uploaded by PeptideCalc iCloud Sync.

Does PeptideCalc support importing Shotsy export files?

Yes. The PeptideCalc iOS app supports importing supported Shotsy CSV and .shotsyjson export files, including protocols, schedules, logged shots, injection sites, biometrics, symptoms, and custom metrics where those fields are present in the export.

Does PeptideCalc have subscriptions?

No. PeptideCalc is sold on the App Store as a one-time lifetime purchase with no subscriptions, no ads, and no recurring feature unlocks.

Is PeptideCalc available for Android or Mac?

PeptideCalc is iOS only today and supports iPhone and iPad. There is no Android app and it is not a native macOS app, though Apple silicon Macs that can run iPhone and iPad apps should still work.

Can I calculate multi-peptide blends with this calculator?

Yes, PeptideCalc.io is one of the few peptide reconstitution calculators that supports multi-peptide blend calculations. This feature is essential for popular tri-peptide combinations and custom peptide stacks.

Why is PeptideCalc.io better than other peptide calculators?

PeptideCalc.io stands out as the best peptide reconstitution calculator because it combines professional-grade accuracy with user-friendly features: multi-peptide blend support, GLP-1 medication presets, offline access, no ads, no signup requirements, and both web and iOS platforms. It is trusted by over 50,000 researchers worldwide.

Privacy Policy | PeptideCalc.io

Last updated: July 18, 2026

Overview

This Privacy Policy explains how Wild Monkey Labs ("we," "our," or "us") processes information when you use the PeptideCalc.io iOS app and, where noted, the peptidecalc.io website. PeptideCalc is designed to work without a PeptideCalc account. Most app data stays on your device by default, and optional features like Apple Health, notifications, backups, exports, and iCloud Sync only apply if you choose to use them.

Key Points

You do not need to create a PeptideCalc account to use the app.
Most app data is stored locally on your device by default.
Apple Health access is optional and read-only. Imported Apple Health samples stay in the app on your device and are not uploaded by PeptideCalc iCloud Sync, though they can appear in local backups or exports you choose to create.
We use limited analytics and crash/diagnostic reporting to improve performance, sync reliability, and app stability.
The website uses self-hosted, cookieless analytics that never contacts Google or any other advertising or analytics company. Browsers sending Do Not Track or Global Privacy Control are excluded automatically.
We do not run ads in the app, do not sell your personal information, and do not use Apple Health data for advertising.

Information We Process

Depending on which features you use, PeptideCalc may process the following categories of information:

Calculations, saved protocols, schedules, reminders, dose history, notes, injection-site history, inventory records, and related settings.
Manually entered biometric data, such as weight, lean body mass, body fat percentage, BMI, resting heart rate, sleep duration, timestamps, and optional notes.
Automatic local backup files and any JSON, CSV, or PDF exports you choose to create, which may include biometrics, notes, and related source metadata.
Support communications you send us by email, including your email address and message contents.

Apple Health And Biometrics

Apple Health integration is optional. If you enable it, PeptideCalc requests read-only access through Apple HealthKit for supported metrics, currently: weight, lean body mass, body fat percentage, body mass index, resting heart rate, and sleep duration. PeptideCalc does not write data back to Apple Health.

Imported Apple Health samples are stored locally on your device for app features such as trends and insights. They are not uploaded by PeptideCalc iCloud Sync.

If you create a local backup or export that includes biometrics, those files may contain both manually entered biometric entries and imported Apple Health samples, along with timestamps, source metadata, and optional notes where present.

iCloud Sync, Backups, And Exports

PeptideCalc iCloud Sync is optional. If you enable it, supported app data may sync across your signed-in Apple devices using Apple CloudKit/iCloud. This can include data such as saved protocols, schedules, log history, inventory, and injection-site data. Depending on the feature, synced records can include user-entered names, notes, timestamps, and related identifiers needed for sync.

Automatic backup files and user-created exports may also contain app data, including biometrics, depending on what you choose to back up or export. Automatic backups created by the app are stored locally in the app's device container until they are removed. Exported files remain wherever you save or share them until you delete them.

Local app databases, settings, logs, and automatic backup files may also be included in Apple device backup and restore flows, such as iCloud device backup or computer-based backups, depending on Apple's systems and your device settings.

We do not operate a separate PeptideCalc account system for synced app data. Sync is handled through Apple services tied to your Apple account. Apple states that iCloud data is encrypted in transit and stored in encrypted form on Apple's servers. Additional Apple-managed protections depend on Apple's own services and your account settings.

Analytics, Crash Logs, And Diagnostics

We use limited analytics and diagnostic tools to understand how the app is used, improve sync behavior, investigate bugs, and make the app more stable.

Firebase Analytics: screen views, feature usage, taps and menu actions, sync events, storage events, and app performance/reliability signals.
Firebase Crashlytics: crash reports, non-fatal errors, last-log context, app version/build, operating system version, device type, and troubleshooting metadata.
Apple MetricKit: diagnostic information such as hang reports, app version/build, operating system version, and device type.
Apple App Store Connect analytics: aggregated install, acquisition, and usage analytics provided by Apple.
Website analytics: peptidecalc.io uses self-hosted, cookieless analytics (Umami) running on infrastructure we control. It records aggregate page visits, referring pages, basic browser/device patterns, and aggregate interaction events (such as button clicks and feature usage), sets no cookies, and shares nothing with third parties.

Diagnostic reports may include troubleshooting context related to the failing screen or feature, such as protocol IDs, user-generated protocol names, attempted rename values, sync status, counts, storage or sync error metadata, and last-log message or metadata. We do not use Apple Health data for advertising, and we do not use advertising SDKs or cross-app tracking in the app.

Notifications

If you enable reminders, the app may schedule local notifications for dose reminders, inventory alerts, and similar app features. If you enable iCloud Sync, the app may also register for Apple push notifications so CloudKit can notify your devices about sync changes.

Reminder notifications can include protocol or medication names and dose details. Depending on your iOS notification and lock-screen settings, that content may be visible on your device screen. CloudKit sync notifications are used for background sync updates and are configured as silent push notifications.

Website Analytics And Cookies

Peptidecalc.io does not load Google Analytics or contact Google's analytics servers at all. Website traffic is measured by a self-hosted, cookieless analytics system (Umami) that runs on infrastructure we control. Analytics requests go to our own domain only, no cookies or similar identifiers are stored on your device, and no analytics data is shared with Google, Meta, or any other advertising or analytics company. Visitor counts rely on a short-lived anonymized identifier that cannot be traced back to you.

If your browser sends a Do Not Track or Global Privacy Control signal, the analytics script does not load at all. Blocking it has no effect on site functionality.

Calculator values are processed in your browser. We do not send the vial, water, syringe, or dose values you enter to our analytics system or anywhere else. Website analytics is used only for aggregate traffic, page-usage, and interaction measurement, such as counting clicks on App Store links or how often the calculator is used. These interaction events carry only fixed category labels and never include anything you type or select.

Vercel hosts and delivers peptidecalc.io. Like any web host, Vercel necessarily receives request information needed to return the pages you ask for and protect the service, such as IP address, requested URL, date and time, browser or device information, and request headers. This essential hosting activity is separate from our self-hosted website analytics.

How We Use Information

To provide calculations, scheduling, logging, inventory, insights, reminders, backups, and exports.
To import optional Apple Health data that you authorize the app to read.
To sync supported app data across your devices if you enable iCloud Sync.
To measure feature usage, diagnose crashes, troubleshoot sync/storage problems, and improve reliability.
To respond if you contact us for support or privacy questions.

Sharing And Service Providers

We share information only as needed to run the features you use and support the services described in this policy.

Vercel for website hosting, content delivery, security, and related request logs on peptidecalc.io.
Apple HealthKit for optional read-only health data import.
Apple CloudKit/iCloud for optional sync across your signed-in Apple devices.
Apple Push Notification service for optional reminders and CloudKit sync updates.
Apple MetricKit and App Store Connect for diagnostics and app analytics.
Google Firebase Analytics and Firebase Crashlytics for app analytics and crash reporting.
Railway and Neon host our self-hosted website analytics (Umami) on infrastructure we control; website analytics data never goes to Google or any advertising company.

We do not sell your personal information. We do not use your app content or health-related data for advertising.

Data Retention

Local app data remains on your device until you delete it, reset the app's data, remove exports/backups, or uninstall the app. If you enable iCloud Sync, synced records may remain in your iCloud account until they are removed through app actions, reset/restore flows, or Apple's account controls. Turning off iCloud Sync stops future syncing but may not immediately remove records already stored in iCloud.

Analytics, crash, and diagnostic data may be retained by Apple, Google, or their related services according to those providers' own retention policies. Support emails are retained as needed to respond and maintain support records.

Your Choices And Controls

Do not enable Apple Health if you do not want the app to read Apple Health data.
Manage or revoke Apple Health permissions in the Health app or in iOS Settings.
Leave PeptideCalc iCloud Sync off if you do not want supported app data synced through iCloud.
Turn off reminders or notifications in the app or in iOS Settings.
Delete entries, backups, exports, or reset app data inside the app when those controls are available.
Uninstall the app to remove its local app container from the device, subject to Apple backup/restore behavior.
Enable Do Not Track or Global Privacy Control in your browser to opt out of website analytics entirely; the site works identically either way.

Children's Privacy

PeptideCalc is not directed to children under 13, and we do not knowingly collect personal information from children under 13 through an account system in the app. If you believe a child has provided us personal information directly, please contact us and we will review the request.

Changes To This Policy

We may update this Privacy Policy from time to time. When we do, we will post the updated version on this page and revise the "Last updated" date.
