Terms of Service
The agreement, in plain language.
These terms describe what we owe you, what you owe us, and what happens when something goes sideways. They're written to be read, not skimmed past. If something here doesn't make sense or you disagree with it, email support@penlog.app.
Who we are
Penlog is operated by RT Indianapolis Holdings LLC, an Indiana limited liability company, doing business as Penlog. References to "we," "us," and "Penlog" mean RT Indianapolis Holdings LLC. References to "you" mean the person using the Penlog app or the Penlog API.
Accepting these terms
By installing Penlog, signing in, or using the Penlog API, you agree to these Terms and to the Privacy Policy. If you don't agree, don't use the service. Apple's standard EULA for App Store apps also applies; where these Terms and Apple's EULA overlap, Apple's EULA controls for the portions Apple has authority over (App Store distribution, in-app purchases, device permissions). For everything else — your content, your account, your subscription with us — these Terms apply.
What Penlog is
Penlog is a handwritten iPad journal. The free tier provides daily writing pages, iCloud sync, paper templates, and basic offline use. The Pro tier (a paid subscription) adds connector sync (Notion, calendar), the structured-data API, the MCP server for agent access, and any other Pro features described in-app or on penlog.app. We may add, change, or remove features. Material changes to Pro features are announced before they take effect.
Eligibility
Penlog isn't directed at children under 13, and you must be at least 13 to use it. If you're between 13 and the age of majority in your jurisdiction, your parent or guardian must agree to these Terms on your behalf.
Your account
Penlog accounts are created via Sign in with Apple. You're responsible for keeping your Apple ID secure and for everything that happens under your account. If you suspect unauthorized access, email support@penlog.app.
You can delete your account at any time in the app via Settings → Delete Account. That permanently removes your account and server-side data per the Privacy Policy. If you can't use the app, email privacy@penlog.app.
Your content stays yours
Everything you create in Penlog — your handwriting, your typed notes, your custom paper templates, your notation legend, your task and event annotations — is yours. We don't claim ownership of any of it. We don't train AI models on your content; we don't sell it; we don't use it for any purpose other than running the service.
We do need a narrow operating license to actually run the service: you grant us permission to store, transmit, render, OCR, sync, and display your content as needed to provide the features you're using. That license is non-exclusive, royalty-free, and lasts only as long as your content is in our system. When you delete content (or your account), the license ends with it.
If you connect Notion, Apple Calendar, or another integration, the data flowing through those connections remains under the rules of those services, in addition to ours. You're responsible for ensuring you have the right to share connected-service data with Penlog.
Subscriptions, trials, and auto-renewal
Pro is offered as an auto-renewing subscription through the App Store. The following terms apply to all paid subscriptions:
- Length and price. Subscription length and price are shown in the App Store and in the in-app purchase confirmation before you subscribe. Current options include Pro Monthly and Pro Annual. Prices are subject to change with at least 30 days' notice for renewals.
- Payment. Apple charges your Apple ID account at confirmation of purchase. We never see your payment information.
- Auto-renewal. Your subscription automatically renews at the end of each subscription period at the same price (or a then-current price as noticed) unless you cancel at least 24 hours before the end of the current period. The renewal charge is applied to your Apple ID account within 24 hours before the period ends.
- Free trials. If your subscription includes a free trial, you can cancel before the trial ends to avoid being charged. Cancellation timing is the same as for paid subscriptions: at least 24 hours before the trial period ends.
- Managing or cancelling. Manage or cancel your subscription in your iOS device's Settings → [your name] → Subscriptions, or via Apple's subscription management page. We can't cancel an active App Store subscription on your behalf.
Refunds
Apple handles billing for App Store subscriptions, so refunds go through Apple. Request one via reportaproblem.apple.com. Apple's refund policies are separate from these Terms. We don't have the ability to issue refunds for App Store purchases.
Acceptable use
You agree not to use Penlog or the Penlog API to:
- Break the law, infringe someone's rights, or engage in harassment.
- Reverse engineer, decompile, or attempt to extract our source code, except to the extent this restriction is unenforceable under applicable law.
- Bypass authentication, rate limits, RLS policies, or any other security control. The MCP server's per-token rate limits exist for everyone's stability — please respect them.
- Upload content that is unlawful, abusive, defamatory, or contains malware. Penlog stores your handwriting; we're not equipped to be a moderation platform.
- Use the API to build a competing product that scrapes, mirrors, or republishes Penlog users' content.
- Resell, sublicense, or commercially redistribute access to Penlog without a written agreement from us.
Third-party services
When you connect Notion, Apple Calendar, or any other integration, you're also bound by that service's terms. We're not responsible for what those services do with the data you send through them, beyond what we control on the Penlog side. Connections are opt-in and revocable at any time from inside the app.
The Penlog API
Pro subscribers can generate API tokens for use with MCP-compatible agents and direct REST access. Tokens are scoped to your account; treat them like passwords. We may revoke tokens that violate these Terms, that we believe are compromised, or whose use threatens service stability. Token plain-text is shown to you once at creation; we store only a hash and cannot recover a lost token. Generate a new one if you need access again.
Termination
You can stop using Penlog at any time. We may suspend or terminate access to the service — free or paid — if you materially breach these Terms (fraud, abuse, security violation, chargeback dispute we lose). For paid subscribers, we'll prorate or refund unused time through Apple where commercially reasonable. We'll give notice via email when we can.
Sections of these Terms that by their nature should survive termination — content ownership, disclaimers, liability limits, governing law — survive.
Disclaimer of warranties
Penlog is provided "as is" and "as available." We don't warrant that the service will be uninterrupted, error-free, or fit for any particular purpose beyond what we describe. We depend on third-party providers (Apple, Supabase, Cloudflare, OpenRouter, Novita, TelemetryDeck, Notion); when one of them has an outage, we may have an outage too. We'll do our best; we can't promise perfection.
Specifically: handwriting recognition is probabilistic. Penlog's OCR is good but not infallible. Don't rely on it for medical, legal, financial, or safety-critical decisions without verifying the original handwritten page.
Limitation of liability
To the maximum extent permitted by law, our total liability to you for any claim arising out of or relating to Penlog is limited to the greater of (a) the amount you paid us in the twelve months preceding the claim, or (b) one hundred U.S. dollars ($100). We're not liable for indirect, incidental, consequential, or punitive damages, including lost profits, lost data, or service interruptions, even if we were warned such damages were possible.
Some jurisdictions don't allow these limits. Where they don't, the limits apply only to the extent permitted.
Indemnification
You agree to defend us against any third-party claim arising from your misuse of Penlog, your violation of these Terms, or your violation of someone else's rights through your use of the service. This is the standard "you cover us if you cause the trouble" clause; we'd rather it never come up.
Governing law and disputes
These Terms are governed by the laws of the State of Indiana, USA, without regard to conflict-of-laws principles. Any dispute that can't be resolved by emailing support@penlog.app will be brought in the state or federal courts located in Marion County, Indiana, and you consent to the personal jurisdiction of those courts.
Changes to these Terms
We may update these Terms from time to time. Material changes — to subscription pricing, the operating license you grant us, or the dispute-resolution clauses — will be announced in-app or by email at least 30 days before they take effect. Non-material changes (like clarifications, typo fixes, or adding a new disclosed third-party processor) take effect when the "Last updated" date at the top of this page changes. Continuing to use Penlog after a material change becomes effective means you accept the change. If you disagree with a material change, your remedy is to delete your account before the change takes effect.
