The short version
- Your writing stays yours. Always.
- The free plan stays free, for as long as you want to use it.
- The Supporter plan is $4 a month and you can cancel anytime.
- Penflow is in private beta. It works well, but we cannot promise zero bugs.
- If Penflow ever shuts down, your local files stay with you.
The service
Penflow is a writing app for novelists. The free plan is the full editor: Write, Codex, Outline, and export for one novel. The Supporter plan adds unlimited novels and optional AI tools, including story chat, proofreading and rewrites for $4 a month.
Penflow is in private beta. We add features and fix bugs as they show up. Use the app knowing that beta software can occasionally misbehave.
Your content
Your manuscript is yours. Penflow does not claim any ownership, license, or rights to the text you write. The desktop app uses local files you control, which you can read, move or delete outside Penflow. Reading and export inside the app require a signed-in account; the free plan includes export for one novel.
Your account
A free account is required to use the desktop app, including reading and export inside Penflow. No payment is required to write and export your first novel. Writing and export work offline while your sign-in remains saved on the device. After signing out or losing that saved sign-in, you need an internet connection to sign in again. Your local files remain accessible outside the app. You are responsible for keeping your login details private. If someone gains access to your account, email [email protected] and we will help.
You can delete your account at any time by emailing us. Local files on your computer stay under your control.
Payment
The Supporter plan is $4 a month, billed monthly. You can cancel at any time from your account. Cancellation takes effect at the end of your current billing period. We do not offer refunds for partial months.
If you use the optional AI tools and bring your own OpenRouter key, you pay OpenRouter directly for model usage. Penflow adds no markup to model usage. Automatic story-note checks also use tokens if you enable them. In version 0.2.15, these checks are off by default and have a separate switch in Account. They propose changes for your review. Turning the switch off stops future checks; a request already sent may finish. Earlier versions could run checks after AI setup. Update the app for the separate switch, or remove your key to stop all AI requests.
Acceptable use
Do not use Penflow to store or generate content that is illegal where you live, infringes someone else's rights, or tries to disrupt the service. If we see this kind of use, we may suspend the account and contact you.
Service provided as is
Penflow is provided "as is." We do our best to keep it running and your data safe. We cannot guarantee the service will be uninterrupted, error-free, or compatible with every device.
To the maximum extent allowed by law, Penflow is not liable for indirect, incidental, or consequential damages arising from your use of the service. Our maximum liability for any claim is limited to the total amount you paid Penflow in the twelve months before the claim.
Changes to these terms
If we change these terms, we update the "Last updated" date at the top. Meaningful changes also go out by email. Continuing to use Penflow after a change means you accept the new terms.
If Penflow ends
If Penflow ever needs to shut down, we will give you at least 30 days notice by email. Your local project folders stay with you regardless.
Governing law
These terms are governed by the laws of Ukraine. If you are based somewhere else, your local consumer protection laws still apply to you.
