Privacy Policy

Last updated: April 28, 2026

At Coal Snap ("we," "us," or "our"), we take your privacy seriously. This Privacy Policy explains how Purr Diem ("the App") collects, uses, and protects your information.

Summary

TL;DR: Purr Diem is designed with privacy in mind. Your expense data stays on your device and in your personal iCloud account. We don't have access to it, we don't sell it, and we don't use it for advertising.

1. Information We Collect

1.1 Information You Provide

When you use Purr Diem, you create and store:

• Event information: Names, dates, budgets, categories, and notes for events you create
• Expense information: Names, amounts, dates, categories, notes, and optional receipt photos for expenses you track
• Per diem information: Per diem rates and calculations you set up

Where this data is stored: All of this information is stored locally on your device and, if you enable iCloud sync, in your personal iCloud account. We do not have access to this data.

1.2 Receipt Photos

If you choose to attach photos of receipts to your expenses:

• Photos are stored locally on your device
• If iCloud sync is enabled, photos sync to your personal iCloud account
• We do not have access to, process, or analyze your receipt images
• No OCR (Optical Character Recognition) or image analysis is performed on our servers

1.3 Information We Don't Collect

We do NOT collect:

• Your name, email address, or contact information (unless you contact support)
• Your location data
• Your browsing history or activity in other apps
• Your financial account information (bank accounts, credit cards, etc.)
• Analytics or usage tracking data
• Device identifiers for advertising purposes

1.4 Subscription Information

If you purchase a premium subscription or lifetime purchase:

• Your payment is processed entirely by Apple through the App Store
• We do not receive or store your payment information
• We receive only a receipt validation token to verify your subscription status
• Apple's privacy policy governs all payment transactions

2. How We Use Your Information

2.1 Primary Purpose

Your expense data is used solely to provide the core functionality of the app:

• Displaying your events and expenses
• Calculating budgets and per diem amounts
• Generating reports and analytics
• Exporting data in PDF or CSV format (Premium feature)

2.2 iCloud Sync

If you enable iCloud sync:

• Your data is encrypted and transmitted to your personal iCloud account
• iCloud sync is governed by Apple's iCloud Terms of Service and Privacy Policy
• We do not have access to your iCloud data
• You can disable iCloud sync at any time in Settings

2.3 Customer Support

If you contact us for support:

• We may collect your email address and any information you voluntarily provide
• This information is used solely to respond to your inquiry
• We do not share this information with third parties
• Support emails are deleted after your issue is resolved (typically 90 days)

3. Data Sharing and Third Parties

3.1 We Don't Sell Your Data

We do not sell, rent, or trade your personal information to third parties. Period.

3.2 Third-Party Services

Purr Diem uses the following Apple services:

• iCloud (optional): For syncing your data across your devices
• StoreKit: For processing in-app purchases and subscriptions

These services are provided by Apple and are governed by Apple's Privacy Policy. We do not share your data with any other third-party services or analytics platforms.

3.3 Legal Requirements

We may disclose information if required to do so by law or in response to valid requests by public authorities (e.g., a court order or subpoena). However, because we don't collect or have access to your expense data, there is very little information we could provide.

4. Data Security

4.1 How We Protect Your Data

• Local storage: Your data is stored securely on your device using iOS secure storage mechanisms
• iCloud encryption: When using iCloud sync, your data is encrypted in transit and at rest
• No server storage: We do not store your expense data on our servers
• Secure communication: All communications with Apple services use industry-standard encryption

4.2 Your Responsibilities

To protect your data:

• Use a strong passcode or biometric authentication on your device
• Keep your device's operating system up to date
• Be careful when exporting data (PDF/CSV files contain unencrypted information)
• Enable two-factor authentication for your Apple ID if using iCloud sync

5. Your Privacy Rights

5.1 Access and Control

Because all your data is stored locally on your device:

• Access: You have full access to all your data at all times within the app
• Export: You can export all your data in CSV or PDF format (Premium feature)
• Delete: You can delete individual expenses, events, or all data directly in the app
• Portability: Your exported data is in standard formats that can be used in other applications

5.2 Deleting Your Data

To completely remove your data:

1. Delete events and expenses within the app, or
2. Uninstall Purr Diem from your device
3. If using iCloud sync, disable iCloud for Purr Diem in Settings > [Your Name] > iCloud

Once deleted, your data cannot be recovered unless you have a device backup.

• Right to access your data
• Right to rectification (correction)
• Right to erasure ("right to be forgotten")
• Right to data portability
• Right to object to processing

Because your data is stored locally on your device, you already have full control over these rights. For questions, contact us at privacy@coalsnap.com.

If you are a California resident, you have rights under the California Consumer Privacy Act (CCPA):

• Right to know what personal information is collected

7. International Data Transfers

• We will update the "Last updated" date at the top of this policy

10. Additional Information

10.1 Data Retention

Your expense data is retained on your device indefinitely until you delete it. We do not impose automatic data retention limits. If using iCloud sync, data retention follows Apple's iCloud storage policies.

10.2 Cookies and Tracking

Purr Diem does not use cookies, tracking pixels, or any form of analytics or advertising tracking within the app.

10.3 Do Not Track

Because we don't track you in the first place, there's nothing to disable. Purr Diem respects your privacy by default.

10.4 Advertising

Free tier users may see advertisements within the app. These ads are provided by Apple's advertising network and are subject to Apple's privacy policy. We do not collect personal information for advertising purposes. Premium subscribers do not see any advertisements.
