Privacy Policy

Effective Date: September 8, 2026

1. Overview and Scope

This Privacy Policy applies to the Android mobile application Peptides Calculator: Dosage, package ID com.rivets.peptidereconstitutioncalculator, published on Google Play by RivetSoft. It also covers the app's official website at https://pepperjourney.com.

RivetSoft is the developer and publishing entity displayed on the app's Google Play store listing and is referred to in this policy as "we," "our," or "us."

2. Information You Enter & 100% Local On-Device Processing

Peptides Calculator: Dosage is designed for private, on-device use:

• Calculation Inputs: When you enter vial masses (mg), diluent/bacteriostatic BAC water volumes (mL), and desired doses (mcg or mg), all arithmetic (concentration, liquid draw volume, and U-100 syringe scale markings) is calculated instantaneously and locally on your device.
• Saved Records & Protocol Logs: Optional profiles, saved vial inventory records, manual schedule entries, and calculation logs are saved strictly in the private, sandboxed app storage of your Android device.
• No Account Required: You do not need to create an account, register an email, provide a phone number, or sign in to use any feature of the application.

3. Data Collection and Sharing (Zero Data Collection)

RivetSoft does not collect, harvest, transmit, or monetize your in-app data.

• No Server Uploads: In-app calculator inputs, vial values, saved schedules, dose logs, and profile nicknames are never uploaded to a RivetSoft server.
• No Advertising SDKs: The app does not include Google AdMob, Unity Ads, Facebook Audience Network, or any other third-party advertising SDK.
• No Analytics or Tracking SDKs: The app does not include Google Analytics for Firebase, Mixpanel, AppsFlyer, or any behavioral tracking SDKs.
• No Sale or Sharing of Data: Because we do not collect your data, we never sell, rent, broker, or disclose your information to third-party data brokers, marketers, or advertisers.

4. Operating System Permissions and Device Features

The application requests only minimal, transparent device permissions strictly necessary for user-initiated functionality:

5. External Links, System Sharing, and Third-Party Services

• System Share & PDF Export: If you choose to export a calculation log or protocol summary as a PDF or text message, the file is compiled locally on your device and handed to the native Android System Share Sheet. Data leaves the app only after you deliberately choose a destination (such as printing, saving to your own Google Drive, or messaging a personal contact). RivetSoft receives no copy.
• PubMed Literature Links: Expanding an educational reference entry allows you to open a research search in the external system web browser on PubMed (National Library of Medicine). When you deliberately tap that action, the compound name is passed into the public PubMed search URL. PubMed and your web browser process that request subject to their respective terms and privacy policies.
• Google Play Services: When downloaded via Google Play, Google may collect technical telemetry (such as OS version, download status, and crash traces) according to Google's own Privacy Policy.

6. Website Request Data (pepperjourney.com)

When you visit our informational website at https://pepperjourney.com, our web hosting provider may log standard HTTP request metadata (such as IP address, browser type, referring page, and request timestamps) for network delivery, DDoS protection, server security, and diagnostic maintenance. The website does not require user accounts, does not use tracking cookies, and does not correlate web traffic with mobile app data.

7. Data Retention, Security, and User Deletion Rights

We believe users should have absolute control over their information:

• Data Retention: Information entered into the app remains strictly on your local device for as long as you choose to keep it installed.
• In-App Deletion: You can purge all saved schedules, logs, and stored calculator entries at any time by opening the Profile, Privacy & Safety modal and tapping “Clear local data”.
• Device-Level Deletion: You can completely clear stored data through Android Settings: Navigate to Settings > Apps > Peptides Calculator: Dosage > Storage & Cache > Clear Storage.
• App Uninstallation: Uninstalling the application immediately and permanently erases all associated application data and cached files from your device.
• Android Cloud Backup Disabled: Cloud application backup is explicitly disabled in the app release manifest (allowBackup="false") to prevent automatic syncing of private records to third-party cloud backups.

8. Children’s Privacy (Google Play Families Policy Compliance)

Peptides Calculator: Dosage is intended exclusively for adults aged 18 and older. The application is not directed to children, and we do not knowingly collect, request, or maintain personal information from individuals under 18 years of age. If you believe an underage individual has entered information, please contact us or utilize the local data clearance procedures described above.

9. Google Play Health Apps Declaration & Regulatory Disclaimers

In accordance with Google Play's Health Apps Policy, Peptides Calculator: Dosage discloses the following functional categories:

• Medical Reference and Education: A curated educational compound index with mechanisms of action and external PubMed research links.
• Medication & Treatment Management: Local, user-directed scheduling tools to record directions provided by a licensed healthcare professional or dispensing pharmacy.
