Yes, CoinLedger is a safe tool to use. It requests read-only access to your crypto exchange account or wallet address, meaning it can’t access your funds in any way.
Furthermore, the company says it doesn’t keep users’ transaction data on its database but rather discards them after extracting the relevant bits.
Any data you send to or receive from CoinLedger is encrypted in transit (256-bit encryption) to prevent unauthorized access and theft.
