Data Retention Policy

Last Updated: August 6, 2025

FogSwap's Approach to Data Retention

At FogSwap, we believe your privacy shouldn't be compromised for convenience. Our data retention practices are designed to balance effective customer support with maximum privacy protection through minimal data storage.

Core Principle: We keep your data only as long as absolutely necessary, then it's gone forever.


⏰ Standard Retention Periods

Transaction Data: 72 Hours

Automatic Deletion Timeline

  • All transaction data is automatically purged after exactly 72 hours
  • No manual intervention required - this happens automatically
  • No exceptions for standard completed transactions
  • Deletion is permanent and cannot be reversed

What Gets Deleted After 72 Hours

  • Wallet addresses (sending and receiving)
  • Token types and quantities
  • Swap routing information
  • Transaction timestamps and processing data

Why 72 Hours?

This timeframe provides the optimal balance between:

  • Customer support: Enough time to resolve most transaction issues
  • Privacy protection: Minimal exposure window for sensitive data
  • Regulatory compliance: Meeting necessary record-keeping requirements
  • Security: Reducing attack surface from stored data

🛠️ Extended Retention for Support Cases

When Data is Retained Longer

If you contact our support team about a transaction issue, we may retain relevant data beyond the standard 72-hour window until your issue is fully resolved.

Extended Retention Criteria

  • Active support case: You've contacted us about a transaction problem
  • Ongoing investigation: We're working with exchange partners on your behalf
  • Pending resolution: Issue requires additional time to resolve
  • Legal hold: Rare cases involving law enforcement requests

What Happens After Resolution

Once your support case is closed:

  • Immediate deletion: Data is purged within 24 hours of case closure
  • Automatic process: No manual steps required
  • Confirmation available: You can request confirmation of deletion
  • Permanent removal: Data cannot be recovered after deletion
Support Trade-off

Extended retention helps us provide better support, but you can always request immediate deletion if you prefer privacy over potential support assistance.


🎛️ User-Controlled Deletion

Immediate Deletion Option

During transaction processing, you can choose to have your data deleted immediately through our "Transaction Processing" page.

How Immediate Deletion Works

  • User choice: Available as an option during transaction processing
  • Instant removal: Data deleted from our systems within minutes
  • No recovery: Once deleted, we cannot retrieve the information
  • Limited support: May impact our ability to help with transaction issues

Trade-offs to Consider

Benefits of Immediate Deletion

  • Maximum privacy protection
  • No data exposure beyond transaction processing
  • Complete control over your information
  • Compliance with strictest privacy preferences

Potential Drawbacks

  • Limited support capabilities if issues arise
  • Difficulty tracking transaction problems
  • Reduced ability to investigate failed swaps
  • No transaction history for reference

🚨 Law Enforcement Cooperation

When law enforcement agencies request information as part of legitimate investigations into illegal activities, FogSwap cooperates to the extent permitted and required by law.

How This Affects Retention

Valid Legal Requests

  • Data may be preserved pending legal review
  • Retention period extended as legally required
  • User notification provided when legally permissible
  • Compliance with court orders and subpoenas

Our Legal Obligations

  • Due process: We verify legitimacy of all requests
  • Minimal disclosure: Only provide data specifically requested
  • Legal review: All requests reviewed by legal counsel
  • User protection: Challenge overly broad or invalid requests
  • Criminal investigations: Serious crimes like money laundering or terrorism
  • Court orders: Legally binding orders from courts
  • Regulatory inquiries: Requests from financial regulators
  • International cooperation: Valid requests through proper legal channels
Legal Limitations

We can only provide data that still exists in our systems. If data has been automatically deleted, we cannot recover it for any purpose, including law enforcement requests.


🔒 Data Security During Retention

Protection Measures

While data is retained in our systems, it's protected by:

Technical Safeguards

  • Encryption: All data encrypted both at rest and in transit
  • Access controls: Strict limitations on who can access data
  • Audit logging: Complete records of all data access
  • Secure servers: Data stored on protected, monitored systems

Operational Safeguards

  • Need-to-know basis: Access limited to specific job functions
  • Regular training: Staff trained on privacy and security protocols
  • Incident response: Procedures for handling any security issues
  • Regular audits: Ongoing review of data handling practices

🔄 Partner Data Retention

Exchange Partner Responsibilities

Our exchange partners maintain their own data retention policies for their portion of transactions:

What Partners May Retain

  • Records of transactions they processed
  • Their portion of swap details
  • Compliance and AML screening records
  • Customer interaction history

Partner Obligations

  • Must meet regulatory requirements for their jurisdiction
  • Follow their own published privacy policies
  • Implement appropriate security measures
  • Cooperate with legitimate legal requests

FogSwap's Role

  • No control: We don't control partner retention practices
  • Due diligence: We vet partners for adequate privacy protections
  • Transparency: We inform users about partner data handling
  • Advocacy: We encourage privacy-friendly practices

📞 Questions About Data Retention

Contact Information

For questions about our data retention practices:

Common Questions

"Can I get confirmation my data was deleted?" Yes, contact our privacy team after the retention period and we can confirm deletion status.

"What if I need transaction records after deletion?" Once deleted, we cannot recover data. Check your wallet and blockchain records for permanent transaction history.

"Do you notify users before extending retention?" We typically only extend retention reactively for active support cases, but you can contact us anytime about your data status.


Privacy Best Practices

For maximum privacy, consider using different wallet addresses for each transaction and enabling immediate deletion during transaction processing.
