• Termination does not automatically delete local data on your device (you can clear it by uninstalling the extension)

3. User Conduct

3.1 Acceptable use

You agree not to use the service to:

• Violate any applicable laws, regulations, or rules
• Infringe or misappropriate the intellectual property, privacy, reputation, or other legal rights of others
• Upload, store, or share any illegal, infringing, defamatory, obscene, discriminatory, threatening, or otherwise inappropriate content

• You represent that you are not barred from using the service under applicable export control and sanctions laws (such as the U.S. Export Administration Regulations, OFAC sanctions, or the EU dual-use regulation), and that your use of the service complies with such laws

3.2 Content responsibility

• You bear full responsibility for all content you create, upload, store, or share through the service (including annotation text, comments, tags, document content, snapshots, and questions and comments in the feedback system)
• You represent and warrant that you own or have obtained the necessary rights to all content you create and share
• We do not review or monitor user-created content and are not responsible for its legality, accuracy, or appropriateness
• If you find that another user's content infringes your rights, notify us through our contact channels. Copyright holders may submit takedown notices through our Copyright Complaints (DMCA) procedure

3.3 Responsibility for the sharing feature

• The sharing feature lets you share annotations with others via share links. You bear full responsibility for what you share and for your sharing activity
• Viewers receive an anonymous temporary identity; your viewers' personal information is not automatically collected
• Sharing of page snapshots (HTML copies of third-party page content) is disabled by default. You can share self-created documents and document snapshots
• You must not share annotations containing other people's personal or sensitive information, or copyrighted content (without authorization)
• If a viewer creates content through the collaborative annotation feature, that content is stored under your account and you are responsible for managing it
• We are not responsible for how viewers use, spread, or misuse shared content

3.4 Third-party websites

• This service runs on third-party websites that you visit. Your use of the service to annotate a third-party website does not imply any endorsement by us of that website or its content
• When annotating third-party websites, you must continue to comply with those websites' own terms of service
• We are not responsible for any consequences arising from your violation of third-party websites' terms
• The technical implementation of the service does not bypass website access controls, paywalls, or login walls

4. Intellectual Property

4.1 Our intellectual property

• The service (including the browser extension code, server-side software, user interface design, icons, and documentation) and all associated intellectual property rights are owned by or licensed to us
• Nothing in these Terms transfers any intellectual property rights in the service to you
• "Sagitnote", "天箭批注", and related marks are our trademarks or registered trademarks

4.2 Your intellectual property

• The intellectual property rights in the annotations, documents, comments, and other content you create using the service belong to you
• You grant us a worldwide, royalty-free, non-transferable, limited license to store, process, and transmit your content solely for the purpose of providing the service to you
• This license ends when you delete the content or your account is terminated (subject to the data-retention provisions above)
• We claim no ownership of your annotation content

4.3 Feedback

If you provide us with feedback, suggestions, or comments about the service, you may provide them freely, but we may use them to improve the service without paying you or assuming any confidentiality obligation.

5. Paid Services and Subscriptions

5.1 Service tiers

The service uses a tiered subscription model. Different tiers offer different feature scopes and usage quotas. The main quotas for each tier are as follows:

"Unlimited" above means no numeric cap applies to that item. These are the quotas currently in effect and may change over time; the Usage panel in the extension always shows the live limits that apply to your account. For feature scope not listed above (such as palette colors), the current information displayed in the service prevails.

5.2 Subscription management and payment

• Purchases and payments for paid subscriptions are completed through the checkout of our payment processor, Waffo Pancake (acting as Merchant of Record, MoR). Waffo Pancake is the seller of record for payment transactions and handles the associated transaction taxes
• We do not collect or store your payment card information: the card data you submit at the checkout goes directly to Waffo Pancake and never passes through our servers; we only receive the order identifier, transaction amount, and payment status needed to activate your service
• You can view and manage your subscription; if a subscription expires without renewal, your service automatically downgrades to the basic tier and the feature scope and quotas are adjusted accordingly
• All fees are as shown in the currency and amount displayed at the checkout at the time of payment

5.3 Refund policy

• Refund process: you can submit a refund request by contacting us or in-app; once the request is approved after review, the refund is returned by Waffo Pancake via the original payment method, and upon approval the corresponding service entitlements (subscription tier and related features) are reclaimed
• EU consumers have the statutory right to withdraw within 14 days of completing payment (subject to statutory exceptions); such withdrawal requests will be handled in accordance with the law
• Unless applicable law requires otherwise, subscription fees already paid are non-refundable
• If a subscription is downgraded or cancelled, you can continue using the current tier until the end of the current billing period
• No prepayment will be refunded where your account is terminated for violating these Terms

5.4 Free tier

• We offer a basic tier of the service whose features and quotas may change at any time
• We reserve the right to modify, suspend, or terminate the basic tier at any time without prior notice

6. Service Availability and Disclaimers

6.1 The service is provided "as is"

The service is provided on an "as is" and "as available" basis, without warranties of any kind, express or implied, including but not limited to:

• Implied warranties of merchantability, fitness for a particular purpose, ownership, and non-infringement
• Any warranty that the service will be uninterrupted, timely, secure, or error-free
• Any warranty that the service will meet all your requirements or expectations
• Any warranty that annotations will be precisely positioned and rendered on any particular web page

6.2 Service interruptions

We are not responsible for unavailability caused by:

• Scheduled maintenance (we will try to give advance notice)
• Server hardware failures, network outages, or other technical problems
• Force majeure events (including but not limited to natural disasters, war, terrorism, civil unrest, epidemics/pandemics, government action, internet infrastructure failures, and power outages)
• Third-party service outages (including but not limited to cloud provider failures and browser extension store issues)
• Your device, browser, or network environment
• Extension compatibility issues caused by browser updates

6.3 Page compatibility

Given the diversity and complexity of pages on the internet, the extension does not guarantee to work on every web page. In particular:

• Some pages may render annotation features partly or wholly unusable due to their technical implementation (special DOM structures, Shadow DOM isolation, dynamic content loading, CSS containment, etc.)
• Some pages may limit parts of the extension's functionality due to security policies (Content Security Policy, cross-origin restrictions, etc.)
• Annotating file:// URLs may be limited by browser security policies
• Annotation may be limited in certain pages (PDF viewers, browser-internal pages, Chrome Web Store pages, etc.)
• Website updates or redesigns may cause existing annotations to be positioned or rendered inaccurately

These are inherent limitations of browser extensions and do not constitute defects in the service.

6.4 Data accuracy and sync

• Annotation positioning on pages depends on the page's DOM structure. Page content changes may shift annotations or make them impossible to restore
• Cross-device sync depends on network connectivity. When the network is unstable or unavailable, sync may be delayed or fail
• Editing the same annotation simultaneously on multiple devices can cause sync conflicts. We use a "last-write-wins" strategy but cannot guarantee perfect merging in all cases
• Using multiple devices to annotate at the same time may cause data conflicts; the consequences are borne by you

6.5 Feature changes

We may add, modify, suspend, or discontinue any feature or part of the service at any time. Where a feature is part of a paid subscription, material changes or discontinuation during a paid term will entitle you to what applicable law provides (which may include a pro-rata refund); in all other cases we will try to give reasonable notice through the extension or our website.

7. Limitation of Liability

7.1 Scope of the limitation

To the maximum extent permitted by applicable law:

• We are not liable for any indirect, incidental, special, punitive, or consequential damages, including but not limited to:
  • Loss or corruption of data
  • Loss of profits
  • Loss of revenue
  • Loss of business opportunities
  • Loss of goodwill
  • Loss of use value
  • Equipment damage or replacement costs
• Our total liability, whether based on contract, tort (including negligence), strict liability, or any other legal theory, shall in no event exceed the amount you paid us for the service in the previous 12 months, or €50, whichever is higher
• Unless mandatory applicable law provides otherwise and only to the extent permitted by law, any claim arising out of or in connection with these Terms or the service must be filed within one (1) year after the claim arises, or it is permanently barred

Nothing in these Terms excludes or limits our liability where and to the extent such exclusion or limitation is not permitted by applicable law, including liability for intent or gross negligence, for death, bodily injury, or damage to health caused by negligence, for fraud, or any other liability that cannot lawfully be limited. To the extent liability for slight (ordinary) negligence may lawfully be limited, this Section 7 applies.

7.2 Data loss

• Although we take reasonable measures to protect your data (including server-side database backups and browser-local storage), we do not guarantee that data will never be lost
• Possible causes of data loss include but are not limited to:
  • Server hardware failure or database corruption
  • Conflicts or errors during sync
  • Browser storage quota exhaustion or cleanup by the browser
  • Browser crashes or abnormal shutdowns
  • Software defects (bugs)
  • Human error
• We recommend that you regularly back up important annotation data using the export feature provided by the extension
• We are not liable for any loss caused by data loss

The service is not a backup service. Any backups we maintain are part of our ordinary operations; we do not guarantee their completeness, recency, or restorability, and we are not obliged to restore data at your request. You are solely responsible for creating and maintaining your own copies of your annotations and documents, including by using the export features provided. Data deleted by you or upon account termination is handled per the Privacy Policy and may be permanently unrecoverable.

7.3 Server outages

• Our server side is deployed on third-party cloud infrastructure whose availability is not fully under our control
• A server outage may cause:
  • Temporary inability to sign in or register
  • Unavailability of sync
  • Temporary inaccessibility of share links
  • Temporary unavailability of cloud image storage
• During an outage your local annotation data is unaffected, and you can continue annotating in pages that are already loaded
• We will try to restore service within a reasonable time, but we are not liable for any loss caused by unavailability

7.4 Third-party conduct

• We are not responsible for:
  • How other users use content you shared with them through the sharing feature
  • Any action taken by a third-party website in response to your annotating its pages
  • Any action taken by a browser extension store in relation to this extension (including delisting or removal)

7.5 Security incidents

You acknowledge that no method of transmission over the internet and no method of electronic storage is completely secure. We implement reasonable technical and organizational measures to protect your data, as described in our Privacy Policy, but we do not warrant or guarantee that the service, the server infrastructure, or any data stored within it will be free from unauthorized access, hacking, data breaches, or other security incidents. In the event of a security incident affecting your personal data, we will notify affected users and supervisory authorities as required by applicable law. To the extent permitted by applicable law, our liability arising from any security incident is subject to the limitations in this Section 7.

8. Indemnification

You agree to indemnify and hold us harmless from any claims, damages, losses, liabilities, and expenses (including reasonable attorneys' fees) arising from:

• Your violation of these Terms
• Content you create, upload, store, or share that infringes third-party rights
• Illegal activities you conduct through the service

9. Third-Party Services

The service may contain links to third-party websites or services, or integrate with third-party services (such as Google / GitHub OAuth sign-in and Waffo Pancake payment processing). Payments for paid subscriptions are processed by Waffo Pancake as Merchant of Record, and payment-related matters between you and Waffo Pancake are also governed by Waffo Pancake's terms and privacy policy. Beyond this, we are not responsible for the content, privacy policies, or practices of third-party services; you use them at your own risk.

10. Privacy

By using the service you agree that we may collect, use, and store your information in accordance with the Sagitnote Privacy Policy (https://www.webnoteshub.com/privacy-policy.html). The Privacy Policy forms part of these Terms.

11. Changes to These Terms

• We reserve the right to modify these Terms at any time
• Material changes will be announced at least 14 days before taking effect, via extension update notices, in-service notices, or email
• Service-essential notices (billing, security, policy changes) may be sent by email as needed; optional product update emails are sent only if you have opted in, as described in the Privacy Policy
• Continued use of the service after a change takes effect constitutes acceptance of the modified Terms
• If you do not agree to the modified Terms, you should stop using the service

12. Governing Law and Dispute Resolution

12.1 Governing law

These Terms are governed by and construed in accordance with German law, without regard to its conflict-of-laws principles.

If you are a consumer with habitual residence in another EU member state, you also enjoy the protections of the mandatory consumer protection laws of your country of habitual residence.

12.2 Dispute resolution

• Before initiating any formal legal proceedings, you agree to first attempt to resolve any dispute amicably by contacting us
• If amicable resolution fails, disputes shall be brought before the courts of Germany having jurisdiction
• These Terms do not affect any statutory rights you have as a consumer under the laws of your country of habitual residence that cannot be excluded by agreement

12.3 Dispute resolution for U.S. users

If you are a consumer resident in the United States, the following applies in addition to (and, where conflicting, instead of) Sections 12.1–12.2, but only to the extent permitted by the law of your state of residence:

• Informal resolution first: before starting arbitration, you must send notice of your claim to service@webnoteshub.com and allow 30 days for good-faith resolution
• Arbitration: disputes not resolved informally will be resolved by final and binding individual arbitration administered by the American Arbitration Association under its Consumer Arbitration Rules, seated in the State of Delaware, United States, conducted in English. Hearings may be conducted by video or telephone where the applicable rules allow. Either party may bring an individual claim in small-claims court instead, if the claim qualifies
• Class action waiver: claims must be brought individually; you and we each waive any right to participate in a class, collective, or representative action, to the extent permitted by law
• Jury trial waiver: you and we each waive any right to a trial by jury, to the extent permitted by law
• 30-day opt-out: you may opt out of the arbitration agreement and the waivers above by emailing service@webnoteshub.com within 30 days of first accepting these Terms (this does not affect Sections 12.1–12.2)
• Severability: if the class action waiver is found unenforceable as to a claim, the arbitration agreement above does not apply to that claim

This Section 12.3 does not apply to consumers whose habitual residence is in the European Union/EEA or the United Kingdom; those users remain subject to Sections 12.1–12.2 and the mandatory consumer protections of their country of habitual residence.

13. Miscellaneous

13.1 Severability

If any provision of these Terms is found invalid or unenforceable, that provision shall be modified or deleted to the minimum extent necessary, and the remaining provisions shall remain fully in force.

13.2 No waiver

Our failure to enforce any right or provision of these Terms does not constitute a waiver of that right or provision. Any waiver is effective only if in writing and signed by our authorized representative.

13.3 Assignment

• You may not assign your rights or obligations under these Terms without our prior written consent (not to be unreasonably withheld)
• We may assign these Terms in the event of a merger, acquisition, asset sale, or as required by law, without your consent

13.4 Entire agreement

These Terms, together with the Privacy Policy, constitute the entire agreement between you and us regarding use of the service and supersede all prior or contemporaneous oral or written communications, proposals, and representations.

13.5 Survival

Provisions of these Terms that by their nature should survive termination (including, without limitation, intellectual property, disclaimers, limitation of liability, indemnification, and governing law) remain in force after your account is terminated.
