Effective November 4, 2026
These terms are the agreement between you and Habittack LLC (“Daily Chain”, “we”, “us”). By creating an account or using the app, you agree to them. Our Privacy Policy explains how we handle your information.
You must be at least 13 years old to use Daily Chain. If you are under the age of majority where you live, a parent or guardian must agree to these terms for you.
You can start with an anonymous account, and you can link a Google account to keep your habits across devices. You are responsible for what happens under your account, so keep your Google sign-in secure and tell us if you think someone else has access.
Packs summarize published research and the recommendations of named experts. Those experts have not reviewed or endorsed Daily Chain unless we say so. Doses, timings and routines in a pack may not suit you.
Talk with a healthcare professional before you start a supplement, change your diet, sleep or exercise, or stop a medication. This matters most if you are pregnant or nursing, have a health condition, or take prescription drugs. If you think you have a medical emergency, call your local emergency number. Never ignore professional advice because of something you read in the app.
| Plan | How it is billed | What to know |
|---|---|---|
| Free | No charge. | Core habit tracking, one Protocol Pack, and the 10 Day grid, with limits on habits, Digital Detox challenges and how far back you can log. Limits can change. |
| Single pack | One payment. | Unlocks that pack for your account. |
| Pro monthly | Renews every month. | Continues until you cancel. |
| Pro annual | Renews every year. | Continues until you cancel. A year of Pro may also be included with a Daily Chain book purchase; that year does not renew. |
| Pro lifetime | One payment. | Lasts for as long as Daily Chain is offered. It is not a promise that the app will run forever. |
Prices, taxes and the exact features in each plan are shown at checkout before you pay. Payments are processed by Stripe. Subscriptions renew automatically at the price shown when you subscribed, unless we tell you about a change in advance and you do not cancel.
You can cancel a subscription from Settings, which opens the Stripe billing portal. Canceling stops the next renewal, and you keep access until the end of the period you already paid for. If you downgrade or your plan ends, habits above the free limits stay in your account and keep working, but you can't add more until you're back under the limit or upgrade.
We offer a full refund on all new purchases within 14 calendar days of the original transaction date. If you are not satisfied with your purchase, you may request a refund within this 14-day window without penalty. To request one, email gethelp@getdailychain.com.
Nothing in this section limits any refund or cancellation rights you have under the law where you live.
You keep ownership of the habits, notes and history you enter. You give us permission to store, sync and display them as needed to run Daily Chain for you. We do not use your entries for advertising and we do not sell them.
Export, clear and delete options are in Settings. Delete account in Settings, available once you sign in with Google, permanently deletes your account, your name, your habits and your history straight away. Our Privacy Policy explains what we collect and what we keep.
The Daily Chain app, name, logo, design and the way we write and arrange pack content belong to us. We give you a personal, non-exclusive, non-transferable license to use them for your own habit tracking. Scientific facts and the names of the researchers we cite remain the work of their respective owners, and any trademarks belong to their owners.
Daily Chain relies on Google Firebase and Stripe. Your use of Google sign-in and Stripe checkout is also covered by their own terms. We are not responsible for services we do not run.
We work to keep Daily Chain running, but it may be unavailable at times, and we may add, change or remove features. We will give reasonable notice before we remove something you paid for.
You can stop using Daily Chain at any time. We may suspend or close an account that breaks these terms or puts the service or other people at risk. Sections that by their nature should continue, such as ownership, disclaimers and liability, continue after your account ends.
Daily Chain is provided as is and as available. We do not promise it will be error-free, uninterrupted, or that it will help you reach a particular health or habit goal.
To the extent the law allows, we are not liable for indirect or consequential losses, lost data or lost profits, or for any decision you make about your health based on the app. Our total liability for any claim is limited to the amount you paid us in the 12 months before the claim, or US$50 if you paid nothing. Some places do not allow these limits, and in that case the limits apply only as far as the law permits. Nothing here limits liability that cannot be limited by law.
These terms are governed by the laws of the State of New Jersey, and disputes will be handled in the state and federal courts located in New Jersey, unless the law where you live gives you the right to bring a claim elsewhere.
We may update these terms. We will change the date at the top, and for significant changes we will tell you in the app. If you keep using Daily Chain after a change takes effect, you accept the new terms. If you do not agree, you can stop using the app and delete your account.
