Terms of use

Last updated September 13, 2026

1. What Hammer is

Hammer is a personal trading journal for crypto and forex. It helps you record trades you have already made and see patterns in them. Hammer is not a broker, exchange, custodian, or investment adviser. It does not execute trades, hold funds, provide market data, or give investment, financial, tax or legal advice. Nothing in the app — including Insights, the weekly review, or any statistic — is a recommendation to buy, sell or hold anything. You are solely responsible for your own trading decisions.

2. Accounts

The Free plan needs no account. A Pro account requires that you be at least 18 years old (or the age of majority where you live, if higher) and that the information you provide is accurate. You're responsible for anything that happens under your account and for keeping your sign-in credentials secure.

3. Subscriptions and billing

Pro is an auto-renewing subscription, billed monthly or yearly. On iPhone, iPad and Mac, purchases, renewals, refunds and cancellations are handled entirely by the App Store under Apple's own terms — we can't issue refunds directly, and cancelling is done in your Apple ID subscription settings, not in Hammer. If a web checkout becomes available, it will state its own processor and terms on the pricing page before you pay. Prices may change; we'll give notice before a change affects an active subscription.

4. Your content

Your trades, notes, tags and attachments are yours. We claim no ownership over them and use them for nothing beyond operating the app for you — showing them back to you, computing your metrics, and, on Pro, syncing them to your own devices. You can export or delete your content at any time (see the privacy policy).

5. Acceptable use

Don't use Hammer to store or share content you don't have the right to, attempt to access another user's data, reverse-engineer the sync protocol to bypass the subscription, or use the service in a way that violates applicable law.

6. Disclaimers

Trading crypto and forex carries substantial risk of loss and is not suitable for every investor. Hammer's metrics, Insights and the written review describe your pasttrades; they are not predictive and are provided “as is” without warranty of accuracy. We work to keep the app available and your data intact, but we don't guarantee uninterrupted service, and to the extent the law allows, we're not liable for trading losses, missed trades, or data loss arising from your use of the app.

7. Limitation of liability

To the maximum extent permitted by law, Hammer's total liability to you for any claim arising from these terms or the app is limited to the amount you paid us in the 12 months before the claim arose.

8. Termination

You can stop using Hammer and delete your account at any time. We may suspend or terminate access for a violation of these terms, with notice where practical.

9. Changes to these terms

We may update these terms as the product changes. Material changes will be announced in the app (Pro) or on this page (Free) before they take effect.
