Terms of Service

Last updated: March 2026

These Terms of Service ("Terms") govern your use of Stashmark, a bookmark management service operated by a sole proprietor based in Amsterdam, the Netherlands ("we", "us", "our"). By creating an account or using Stashmark, you agree to these Terms.

1. Acceptance of Terms

By accessing or using Stashmark, you confirm that you are at least 16 years old (as required by Dutch law) and agree to be bound by these Terms and our Privacy Policy. If you do not agree, do not use the service.

2. The Service

Stashmark is a bookmark management service that lets you save, organize, highlight, and access web content across devices. We provide:

  • A web application at app.stashmark.app
  • Browser extensions for Chrome, Firefox, and Edge
  • Mobile applications for iOS and Android
  • An API for programmatic access

Stashmark is also available as open-source software for self-hosting. These Terms apply only to the cloud-hosted service at app.stashmark.app. If you self-host Stashmark, you are responsible for your own instance and these Terms do not apply.

3. Account Responsibilities

  • You must provide accurate information when creating your account.
  • You are responsible for keeping your password secure. We recommend enabling two-factor authentication (2FA).
  • You are responsible for all activity that occurs under your account.
  • Notify us immediately at support@stashmark.app if you suspect unauthorized access to your account.
  • One person or entity per account. Accounts cannot be shared.

4. Your Content

You own your content. Bookmarks, highlights, notes, folders, tags, and any other content you create or save using Stashmark remain yours.

You grant us a limited, non-exclusive license to store, display, and transmit your content solely as necessary to provide the service. This license ends when you delete your content or your account.

We do not access, analyze, sell, or use your content for any purpose other than providing the service. We do not train AI models on your data.

You can export all your data at any time in standard formats (JSON, HTML, CSV) from your account settings.

5. Acceptable Use

You agree not to use Stashmark to:

  • Store, share, or distribute content that is illegal under Dutch or EU law
  • Upload malware, viruses, or other harmful code
  • Attempt to gain unauthorized access to the service, other users' accounts, or our infrastructure
  • Use automated tools to scrape, crawl, or bulk-access the service beyond the provided API
  • Impersonate another person or entity
  • Use the service to send spam or unsolicited messages
  • Reverse engineer, decompile, or disassemble the service (except as permitted by applicable law)
  • Interfere with or disrupt the service's operation
  • Resell or redistribute access to the service without our written permission

We may suspend or terminate accounts that violate these rules, with notice where practicable.

6. Subscriptions and Billing

Stashmark offers free and paid subscription plans. Paid subscriptions are processed by Polar.sh, which acts as our merchant of record.

  • Subscription fees are billed in advance on a monthly or annual basis.
  • You can cancel your subscription at any time from your account settings. Cancellation takes effect at the end of the current billing period.
  • Refunds are handled in accordance with Polar.sh's refund policy and applicable EU consumer protection law.
  • We may change pricing with at least 30 days' notice. Price changes do not affect your current billing period.
  • If payment fails, we will notify you and may downgrade your account to the free plan after a reasonable grace period.

7. Intellectual Property

The Stashmark name, logo, design, and software (excluding open-source components) are our intellectual property. You may not copy, modify, or distribute these without our written permission.

Stashmark's source code is available under an open-source license. Your use of the source code is governed by that license, not these Terms.

8. Termination

By you:

  • You can delete your account at any time from your account settings.
  • We recommend exporting your data before deletion.
  • Upon deletion, all your data will be permanently removed within 30 days.

By us:

  • We may suspend or terminate your account if you violate these Terms.
  • Where possible, we will provide notice and an opportunity to export your data before termination.
  • If we discontinue the service entirely, we will provide at least 90 days' notice and the ability to export your data.

9. Disclaimer

Stashmark is provided "as is" and "as available" without warranties of any kind, whether express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, and non-infringement.

We do not guarantee that the service will be uninterrupted, error-free, or that any content you save will be preserved indefinitely. We recommend maintaining your own backups using the export feature.

10. Limitation of Liability

To the maximum extent permitted by applicable law, our total liability for any claims arising from your use of the service is limited to the amount you have paid us in the 12 months preceding the claim, or €100, whichever is greater.

We are not liable for indirect, incidental, special, consequential, or punitive damages, including loss of data, revenue, or business opportunities.

Nothing in these Terms excludes or limits liability for fraud, gross negligence, or any liability that cannot be excluded under Dutch or EU law.

11. Governing Law and Disputes

These Terms are governed by the laws of the Netherlands. Any disputes will be submitted to the competent court in Amsterdam, the Netherlands.

If you are an EU consumer, you retain the right to bring proceedings in the courts of your country of residence. Nothing in these Terms affects your statutory consumer rights under EU law.

You may also use the European Commission's Online Dispute Resolution platform.

12. Changes to These Terms

We may update these Terms from time to time. If we make material changes, we will notify you by email or by displaying a prominent notice in the application at least 30 days before the changes take effect.

Continued use of the service after the changes take effect constitutes acceptance of the new Terms. If you do not agree with the changes, you may delete your account before they take effect.
