Terms and Conditions
Knotbook is a product of Spyxpo, operated by Spyxpo Technologies Private Limited (CIN U62011BR2025PTC079225), registered office C/O Krishna Murari Kumar, Begusarai, Bihar 851101, India ("Spyxpo", "we"). Effective 2026-09-25.
These terms cover the Knotbook desktop application and Knotbook Pro. Use of the knotbook.app website is covered by the Terms of Use.
By installing or using Knotbook you agree to these terms. If you do not agree, do not use the software.
1. Licence
Spyxpo grants you a personal, non-exclusive, non-transferable licence to install and use Knotbook.
The free tier is free to use for as long as you like, personally or commercially. Pro is a one-time purchase, not a subscription, valid on up to 3 devices at a time; the free tier has no device limit. You can free a device slot in Settings.
This is a licence to use. The software is proprietary and is not open source. See LICENSE.
2. What you may not do
- Redistribute, resell, sublicense or rent Knotbook, or the Pro licence key.
- Reverse engineer, decompile or disassemble it, except where that right cannot lawfully be excluded.
- Circumvent the licensing to obtain Pro features without buying them.
- Remove or alter the notices in the software.
3. Your content is yours
Your notes are your property. Spyxpo claims no rights over them and holds no copy — they are files on your disk. You are responsible for backing them up.
4. Software under active development
Knotbook is under active development and may contain defects. Do not use it as the only copy of anything you cannot afford to lose. Because notes are plain markdown files in a folder you control, an ordinary file backup protects them completely, and we recommend one.
5. Payment and no refunds
Pro is sold through Razorpay. Prices are shown at checkout and may change; a change never affects a licence already bought.
All purchases are final. Once a payment is complete it is not refundable, so try the free version before you buy. This does not affect any right to a refund that applicable law gives you and that cannot be excluded, and it does not apply to a duplicate charge or a payment that produced no licence: email support@spyxpo.com with your Razorpay payment ID and we will correct it.
6. Third-party services
Knotbook can, at your direction, connect to third-party services — model hosts, a search engine, your payment provider. Their terms apply to those interactions. PRIVACY.md lists every one.
7. Availability
The licence server, update endpoint and website are provided on a best-efforts basis without an uptime guarantee. Knotbook keeps working offline, including a Pro licence already activated on a device.
8. Warranty
To the fullest extent the law allows, Knotbook is provided "as is" without warranty of any kind. Nothing here excludes liability that cannot lawfully be excluded, and consumer rights under Indian law are unaffected.
9. Liability
To the extent the law allows, Spyxpo's total liability under these terms is limited to the amount you paid for Knotbook in the 12 months before the claim. We are not liable for lost data, lost profits, or indirect losses.
10. Termination
The licence ends if you materially breach these terms. On termination, stop using the software and remove it. Your notes remain yours and remain on your disk — they are not affected.
11. Governing law
These terms are governed by the laws of India. The courts at Begusarai, Bihar, India have exclusive jurisdiction, without prejudice to any right you have to bring proceedings where you live.
12. Changes
Material changes are announced in the app and the effective date changes. Continuing to use Knotbook after a revision means accepting it.
