Privacy policy
SizeGuard 1.0.0 · Effective October 25, 2026
The short version
SizeGuard does not collect, share or sell any personal data. Everything you type stays on your device.
What the app stores on your device
Your risk settings, daily loss limit and fees, chosen market and contract, your last calculation, your trading journals (trades, pending orders, setups, mistakes and notes), your Daily Journal pages, your Prop Firms entries, your trial start date, whether you unlocked the app, and any creator code you typed. All of it is saved in the app’s private storage on your device, so the app opens where you left off. Nothing is sent to us or anyone else.
Files you choose to export (such as a CSV of your trades or a backup) go only where you send or save them.
Purchases
The one-time Unlock is bought through the Apple App Store or Google Play. Apple or Google handle the payment under their own privacy policies. We never see your name, card or account details.
Keeping or deleting your data
Your data stays until you delete it. You can delete single trades, days and entries inside the app. To delete everything, uninstall the app or clear its data in your phone’s settings. Your phone’s own backups (iCloud or Google) may include this data, according to your device settings. If you tap Back up, the app makes one file with this data and opens your phone’s share sheet; the file goes only where you choose to save or send it (for example iCloud Drive, Google Drive or your email), and Restore reads such a file back from your phone. A backup never contains your purchase. Because we never receive your data, there is nothing for us to delete on our side.
What the app does not do
- No account or sign-in.
- No advertising, analytics or tracking, and no third-party SDKs that collect data.
- No broker connection, orders or live market data.
- No internet connection is needed.

Terms of use
- Not financial advice. SizeGuard is a calculator and journal. It does not place trades, connect to brokers, provide market data or recommend any trade. You alone decide what and how much to trade.
- Estimates only. Results cover the stop distance plus any fees you enter. They exclude slippage, price gaps, margin requirements and any fees you don’t enter, so real losses can be larger. Confirm contract specifications with your broker.
- Trading is risky. Futures, Forex, crypto and stocks can lose more than you expect. The publisher is not responsible for trading losses.
- Free trial and Unlock. All features are free for 7 days from when you start the trial. After that the app locks until you buy the one-time Unlock ($9.99 in the US; local prices may differ). Nothing is charged automatically and there is no subscription.
- On iPhone, Apple’s Standard End User License Agreement also applies.
About the calculations
Futures standard and micro results are separate alternatives. Stocks use whole shares; crypto uses your broker’s coin increment in USD-quoted pairs; Forex covers EUR/USD, GBP/USD, AUD/USD and NZD/USD at $10 per pip per standard lot (100,000 units). Contract specifications were checked October 20, 2026.
