Grynd · Solto Apps
Terms of Use
Last updated October 12, 2026
These Terms of Use ("Terms") are an agreement between you and Solto Apps for the Grynd apps on iOS and Android and the site at grynd.soltoapps.top (the "Service"). By downloading Grynd, creating an account, or using the Service, you agree to these Terms and to the Privacy Policy. If you do not agree, do not use Grynd.
1. The Service
Grynd is a tool for writing a training plan, logging sessions, reviewing your history, and optionally sharing a week with a team. It records what you enter. It is not a medical device, not a coaching service, and not a promise of any fitness, health, or performance result.
Grynd is offered by Solto Apps without a subscription fee charged by us. If we introduce a paid plan, we will tell you before you are charged. Apple or Google may still apply their own terms to the download.
2. Training risk
Exercise can cause injury. You are responsible for the loads, durations, and programs you enter, and for training within your own limits. Talk to a qualified professional before you start or change a program, particularly if you are pregnant, injured, or managing a health condition. We do not review your logs for safety, and rest timers are reminders, not medical guidance.
3. Who may use Grynd
You must be able to enter a binding contract where you live. Grynd is not offered to children under 13. If you publish a plan for a team, you are responsible for having permission to invite those people and for the training you assign.
4. Accounts
An account is optional for personal logging and required for cloud sync and teams. You agree to use an email address you control, to keep your password confidential, and to tell us if you believe the account has been misused. You are responsible for activity under your account.
Password reset is sent through Firebase Authentication to the email on the account. We may refuse, suspend, or close an account that breaks these Terms, or that we reasonably believe is being used to harm the Service or another person.
5. Teams
A coach creates a team, a join code, and a team password. Anyone who has both the code and the password can join. Share them only with people who should see the plan and the chat. Coaches can view team-linked sessions and recent progress for members. Members can see the shared plan and the group chat.
You will not use a team to collect information you are not entitled to collect, or to watch someone who has not chosen to join. The team password is not your account password. Treat a leaked code as a reason to create a new team.
6. Acceptable use
You agree not to:
- Break the law, or infringe someone else's rights
- Harass, threaten, or post abusive, exploitative, or illegal content in chat
- Try to send images, video, or files in chat
- Probe, scrape, overload, or disrupt the Service, or access another person's account
- Misrepresent who you are, or who runs a team
- Harvest other people's logs to build a competing dataset
- Reverse engineer the apps except where a law that applies to you does not allow us to restrict that
Chat is text only and limited to 2,000 characters a message. The product does not edit or delete a message after it is sent. We may remove content or a team if we learn that it violates these Terms.
7. Your logs and messages
You keep ownership of the routines, workout logs, and messages you create. You give Solto Apps a limited license to host, store, and display that content only to operate Grynd for you and, where you have joined a team, for that team. The license ends when the content is deleted from our systems, except where a copy has to remain in a shared team record or where we must keep it for a legal reason. The Privacy Policy describes deletion.
8. Your device and offline use
Personal data can remain on the phone. You are responsible for the device, for backups, and for local logs that disappear if you delete the app or its data. Cloud sync and team sync need a network connection to finish. We do not promise that every offline edit will merge without a conflict.
9. Our intellectual property
Grynd, the name, the app icon, the software, and this website belong to Solto Apps or its licensors. These Terms do not transfer any ownership to you. You may not copy the apps, the exercise catalog, or the site except for ordinary personal use, or where the law allows a wider use.
10. App stores
If you install Grynd from the Apple App Store or Google Play, that store's terms also apply to the download and to any billing the store processes. Apple and Google are not responsible for the Service itself. Store availability can change, and a listing marked as coming soon on our website is not a release date.
11. Changes to the Service and to these Terms
We may add, change, or remove features, including teams or sync, and we may update these Terms. The date at the top of this page will change when we do. If you keep using Grynd after an update, the new Terms apply. If you do not agree, stop using the Service and delete your account from Profile.
12. Disclaimer
The Service is provided "as is" and "as available." To the fullest extent the law allows, we disclaim warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that logs will be free of errors, that charts will be complete, or that the Service will be uninterrupted. Some places do not allow these disclaimers. Where that is the case, they apply only as far as the law permits.
13. Limitation of liability
To the fullest extent the law allows, Solto Apps and its people are not liable for indirect, incidental, special, consequential, or punitive damages, or for lost profits, lost data, or injury arising from training you chose to perform, even if we were told that such damages were possible. Our total liability for a claim relating to the Service is limited to the greater of the amount you paid Solto Apps for Grynd in the three months before the claim, or fifty US dollars.
Some places do not allow these limits. They apply only as far as the law permits. Nothing in these Terms limits liability that cannot legally be limited, including liability for fraud, or for death or personal injury caused by negligence where the law forbids that limit.
14. Your responsibility for misuse
If you misuse a team, post unlawful chat, or use Grynd in a way that harms another person, you will indemnify Solto Apps against the resulting claims, losses, and reasonable legal costs, to the extent the law allows.
15. Stopping
You may stop at any time. Deleting the account in Profile removes the authentication user and the Grynd profile, as described in the Privacy Policy. We may stop providing the Service to you if you break these Terms, or if we discontinue Grynd. Sections that by their nature should continue — including ownership, disclaimers, liability limits, and indemnity — remain in effect.
16. Disputes
Email hello@soltoapps.top first and we will try to resolve a dispute informally. These Terms do not take away non-waivable rights you have under the law of the country where you live, including any right to bring a claim in your local courts.
17. Whole agreement
These Terms and the Privacy Policy are the whole agreement between you and Solto Apps about Grynd. If a court holds one provision unenforceable, the rest stays in effect. A failure to enforce a provision is not a waiver.
