Terms of Service
Last updated: May 23, 2026. Governing entity: Regios GmbH / Peak Productivity.
1. Acceptance of terms
By installing or using YouTube Subtitle Downloader (the "Extension"), you agree to these Terms of Service. If you do not agree, please uninstall the Extension. These terms are governed by the laws of Switzerland.
2. Description of service
YouTube Subtitle Downloader is a Chrome extension that allows users to download subtitle and caption files (SRT, VTT, TXT) from YouTube videos they are currently viewing. The Extension does not download video content, audio, or any media files. It accesses only caption data that YouTube makes publicly available to authenticated viewers.
The Extension is developed and operated by Regios GmbH, trading as Peak Productivity. It is not affiliated with, endorsed by, or connected to YouTube, Google LLC, or Alphabet Inc.
3. Acceptable use
You may use the Extension for personal, research, accessibility, educational, or commercial purposes, subject to the following restrictions:
- You must comply with YouTube's Terms of Service when accessing YouTube content.
- You must comply with applicable copyright law. Downloaded subtitle files may be protected by copyright. Using subtitle files for purposes that infringe on creators' rights is your responsibility, not ours.
- You may not use the Extension to circumvent access controls, distribute subtitle files commercially without authorization, or facilitate any activity that violates applicable law.
- You may not attempt to reverse-engineer, decompile, or extract proprietary components of the Extension.
4. Free tier
The Free tier provides 5 subtitle downloads per day at no cost. No account or payment card is required. Free tier users have access to all three output formats (SRT, VTT, TXT) and all available caption languages. The Free tier is provided without warranty and may be modified or discontinued with notice.
5. Pro subscription and billing
Pro plans are offered at $5.00/month (monthly) or $39.00/year (annual). Subscriptions are processed by Stripe. By subscribing, you authorize recurring charges at the selected billing interval until you cancel.
- Cancellation: you may cancel at any time from your Stripe customer portal or by emailing support@peakproductivity.online. Cancellation takes effect at the end of the current billing period. No partial refunds for unused time.
- Refunds: within 30 days of any initial purchase or renewal, we will issue a full refund on request, no questions asked. After 30 days, all charges are final.
- Price changes: we will give at least 30 days notice before changing subscription prices. Continuing to use Pro after the effective date constitutes acceptance of the new price.
6. License
A Pro subscription grants you a non-exclusive, non-transferable, revocable license to use the Pro features of the Extension during your subscription period. You may use the same subscription on multiple Chrome installations that you personally use. Sharing, reselling, or sublicensing your subscription to other users will result in immediate revocation without refund.
7. Pro AI translation
The Pro AI translation feature uses GLM AI to translate subtitle files. Translation quality varies by language pair and source quality. We do not warrant that translations will be accurate, complete, or suitable for any particular purpose. Translation requests are processed by our server and GLM's systems as described in our Privacy Policy.
8. Fair use and abuse
Pro subscriptions are intended for individual use. Automated bulk downloading or API scraping via the Extension in a manner that places excessive load on YouTube's infrastructure is prohibited. We reserve the right to suspend accounts found to be abusing the service.
9. Disclaimer of warranties
The Extension is provided "as is" and "as available" without warranty of any kind, express or implied. We do not warrant that the Extension will always function without interruption or error. YouTube changes its platform and caption systems from time to time, which may temporarily affect Extension functionality. We will make commercially reasonable efforts to restore compatibility promptly.
10. Limitation of liability
To the maximum extent permitted by applicable law, Regios GmbH / Peak Productivity shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of the Extension. Our total liability to you for any claims under these terms shall not exceed the amount you paid us in the three months preceding the claim.
11. Changes to these terms
We may update these terms from time to time. We will update the "Last updated" date above and notify users of material changes via a notice in the Extension or on our website. Continued use of the Extension after the effective date of any change constitutes acceptance of the updated terms.
12. Governing law and disputes
These terms are governed by the laws of Switzerland. Any disputes arising from these terms shall be submitted to the courts of Zurich, Switzerland, unless applicable consumer protection law in your country requires otherwise.
