Size Down — last updated September 5, 2026
A journal and calculator for your own trading. It does not place trades, provide signals, recommend securities, or promise any result. Nothing in the app is financial, investment or tax advice. Trading involves substantial risk of loss; you are responsible for your decisions and for verifying your prop firm’s current rules, which change often.
Adults, 18 and over. One account per person.
Size Down Pro is sold via Stripe. The monthly plan renews automatically until you cancel; cancel any time from the link in your Stripe receipt or by emailing us, and access continues to the end of the paid period. Lifetime is a single charge for as long as Size Down is operated. Pro is attached to the anonymous account it was purchased under; use the restore option with your Stripe checkout session id, or email support, to move it to a new device. Refunds: within 14 days of a first purchase, on request.
You own what you enter. You grant us a licence to store and process it so the app works. You may export it with Pro and delete it at any time.
Size Down is provided as is. To the extent the law allows, Forma is not liable for trading losses or any indirect or consequential damages arising from use of the app, including errors in calculations. Check the numbers against your broker and your firm.
We may update these terms; the date above changes when we do. tryformaapp@gmail.com
