Terms of service
Effective November 10, 2026
The short version
- Towerly is beta software. It will have rough edges.
- Your mail is yours. We only use it to run Towerly for you.
- Drafts are written by AI and can be wrong. Read before you approve.
- Anything sent after you approve it is sent by you.
1. These terms
These terms are an agreement between you and Derik Silva, who operates Towerly (“Towerly”, “we”, “us”). By using the Towerly apps or this website, you agree to them. If you don’t agree, please don’t use Towerly.
2. Who can use Towerly
You must be at least 18. You may connect only mail accounts that you own or are allowed to use. If you connect a work account, make sure your employer permits it.
3. Beta software
Towerly is in private beta. Features may change or be removed, and the service may be interrupted. Please keep using your regular mail app alongside it until you trust it.
4. How Towerly acts for you
Towerly reads the accounts you connect and prepares proposals such as draft replies and calendar holds. A proposal does nothing until you approve it. When you approve a draft, or write and send a message yourself, Towerly sends it from your account on your instruction. You are responsible for what you send.
Drafts, summaries and sorting are produced by AI and may be inaccurate or incomplete. Review them before you rely on them.
5. Your content
You keep all rights to your mail and other content. You give us permission to store and process it only as needed to provide Towerly to you, as described in the privacy policy.
6. Acceptable use
- Don’t use Towerly to send spam or to break the law.
- Don’t use it to harass, deceive or harm anyone.
- Don’t try to access other people’s data, probe or disrupt the service, or get around its limits.
- Don’t resell Towerly or build a competing service from it.
7. Price
Towerly is free during the beta. If we introduce paid plans, we will tell you the price before you are charged anything, and you can choose not to continue.
8. Other services
Towerly works with services run by other companies, such as your mail provider, Apple and Google. Their terms apply to your use of those services, and we are not responsible for them.
9. Our property
The Towerly apps, name and logo belong to us. We give you a personal, non-transferable licence to use the apps while these terms are in effect.
10. Ending your use
You can stop using Towerly at any time and ask us to delete your account. We may suspend or end your access if you break these terms or if we stop offering the service. Where we can, we will give you notice.
11. No warranty
Towerly is provided “as is” and “as available”. To the fullest extent the law allows, we make no warranties of any kind, including that the service will be uninterrupted, error-free, or that drafts and sorting will be accurate.
12. Limit of liability
To the fullest extent the law allows, we are not liable for indirect, incidental, special or consequential damages, or for lost profits, data or goodwill. Our total liability for any claim relating to Towerly is limited to the greater of what you paid us in the twelve months before the claim or fifty US dollars.
13. Governing law
These terms are governed by the laws of the State of California. Any dispute will be handled in the state or federal courts located in Contra Costa County, California.
14. Changes
We may update these terms. If a change is significant, we will tell you in the app or by email before it takes effect. If you keep using Towerly after that, you accept the new terms.
