How to compare privacy policies across swap services

05 September 2026

You compare privacy policies across swap services by checking what data each service collects, how long they retain it, and whether they share it with third parties. The differences between services are often dramatic, and the phrasing of a policy can hide tracking that a competitor openly forbids.

What to look for in a privacy policy

Every swap service that works without an account still has servers, logs, and payment processors. A privacy policy is a legal document that describes what the service does with the information those systems generate. Focus on three elements.

Data collected

The policy should list every piece of data the service records. Common items are IP addresses, browser fingerprints, device identifiers, transaction amounts, timestamps, and destination wallet addresses. Some services collect only the minimum needed to process the swap - often just the transaction hash and the amount. Others log the full network path, including the IP that initiated the request, and store it indefinitely.

Look for phrasing like "we may collect" versus "we collect." "May" is a loophole. If the policy says it collects data "for operational purposes" without specifying what, treat that as permission to log anything.

Retention period

How long does the service keep the data? Some policies state a fixed period - 24 hours, 30 days, or 90 days. Others say "as long as necessary" or "in accordance with legal obligations." Those vague terms mean the service can keep your data indefinitely and change the duration without notice.

A clear policy names the retention period explicitly. If it does not, assume the data is kept until the service decides to delete it.

Third-party sharing

Does the service share data with analytics companies, cloud providers, or law enforcement? Many services use third-party APIs for exchange rates, transaction verification, or fraud detection. Each third party has its own privacy policy, and the swap service may not control what that third party does with your data.

The policy should name every third party that receives data and explain what data they receive. If it says "we may share data with trusted partners" without naming them, you cannot verify what happens to your information.

What to watch for

IP logging

An IP address is the single most identifiable piece of data a swap service can collect. Some services block IP logging entirely. Others log it temporarily to prevent abuse or fraud. A policy that does not mention IP addresses is likely collecting them.

Wallet address correlation

If the service logs your destination address alongside your IP, it creates a permanent link between your identity (via your internet connection) and your wallet. This defeats the purpose of swapping without an account. Check whether the policy states that wallet addresses are not stored with IPs.

Changes to the policy

Services can update their privacy policies at any time. A policy that says "we will notify you of changes" is useless if you do not provide an email address - which you should not, since you are swapping without an account. Bookmark the policy and check it periodically, or use a service that publishes a public changelog.

Practical steps

1. Read the policy completely before your first swap. Do not rely on a summary.
2. Compare the data collected, retention period, and third-party sharing across at least three services.
3. If a policy is missing or unreadable, do not use the service. No document means no promises.
4. Use a service that accepts cryptocurrency for swaps and does not require any personal information - this is the subject covered in the hub page "Swapping crypto without an account."

The honest bottom line

Most privacy policies are written to protect the service, not you. A service that collects minimal data and deletes it quickly has a short, clear policy. A long policy full of exceptions and legal jargon usually means the service reserves the right to log and share more than it admits. Compare the words, but also compare the length. Short often means less tracking.
