Is my data safe?
Absolutely. All your data is stored locally on your device. Nothing is sent to our servers or any third party. There is no account, no login, and no cloud sync. You are in full control of your data. See our Privacy Policy for details.
Which tax rules does the app use?
The app uses HMRC's Section 104 pooling method to calculate capital gains. It also estimates income tax on mining, staking, and active airdrop rewards using current UK tax rates and the £1,000 trading allowance. Note: the app does not currently implement Same Day or 30-Day (Bed & Breakfast) matching rules.
Can I use this for my Self Assessment?
No. This app is strictly an educational tool and tax estimation aid. It is not a regulated tax service and must not be used for filing tax returns, Self Assessments, or any official HMRC submissions. The figures provided are estimates only and may not reflect your actual tax liability. You must always consult a qualified tax adviser or accountant before making any tax filing decisions.
How do I add staking rewards?
Go to the Transactions tab and use the "Add Staking" option. You can enter monthly staking rewards in bulk, and the app will automatically fetch average monthly prices for each entry.
What's the difference between active and passive airdrops?
Passive airdrops are tokens received without any action on your part — they have a £0 cost basis and are not subject to income tax. Active airdrops are earned by performing a task (e.g., signing up, sharing) — their fair market value at receipt counts as taxable income and forms the cost basis in your S104 pool.
Can I back up my data?
Yes. Go to Settings > Export Backup to save all your transactions as a JSON file. You can restore from this file at any time using Settings > Restore Backup.
Where do the prices come from?
Historical and current prices are fetched from the Binance API (converted to GBP via the Frankfurter exchange rate API). If a price cannot be found automatically, you can enter it manually.
I found a bug. How do I report it?
Please email us at support@evertonmonkey.co.uk with a description of the issue, your device type, and the steps to reproduce it. Screenshots are always helpful!
