Terms of Service for WonderPen

Thank you for using WonderPen. These Terms explain software licensing, membership benefits, cloud data, and support. Please pay particular attention to membership expiry, refunds, data retention, service changes, and liability.

1. Parties and scope

1.1These Terms are between you and Hangzhou Tongming Technology Co., Ltd. (“we” or “us”). They apply to WonderPen’s desktop, mobile, and web versions, and our account, licensing, cloud storage, and synchronization services. Features vary by platform, version, and membership plan according to the relevant product descriptions and benefits confirmed when you purchase.

1.2Website services, TominLab accounts, and website transactions are also governed by the website Terms of Service. These product-specific Terms take precedence for matters they expressly address concerning WonderPen use, membership, and Library data. The website Terms apply to other matters. Mandatory provisions of applicable law remain unaffected.

1.3These Terms are available in Chinese and English. In the event of any inconsistency or difference in interpretation, the Chinese version prevails, except where mandatory provisions of applicable law require otherwise.

1.4WonderPen does not provide AI services. We will not use your documents, attachments, or other user data to train AI models, or provide that data to third parties for that purpose.

2. Accounts and licenses

2.1You may use the features available without signing in. Features requiring cloud storage, cross-device synchronization, or account benefits require registration or sign-in through the relevant entry point. Local features that do not require an account are separate from online account services.

2.2Provide accurate and valid account information, keep credentials secure, and contact us promptly if you discover unauthorized use. Responsibility for account incidents is determined under Section 8 and applicable law.

2.3A purchase grants the usage license for the relevant platform, version, or membership plan; it does not transfer intellectual property in the software. Lifetime Pro benefits cover the platforms and features confirmed when purchased or granted. They do not automatically include Pro+ cloud benefits or mean that all online services will be provided forever.

2.4You must not sell, rent, or share an account or license in a way that circumvents licensing restrictions. Normal device changes, reinstallation, license transfers, and upgrades follow the product’s license management rules.

3. Memberships, renewals, and expiry

3.1Basic, Pro, and Pro+ features, allowances, duration, and prices are those specified in the product descriptions, membership benefits page, and order at purchase. We will honor confirmed commitments; later changes will not retrospectively reduce purchased rights.

3.2Website purchases do not renew automatically or trigger automatic charges. Auto-renewing subscriptions through Apple follow Apple’s purchase screen and subscription rules. You can cancel future renewals through Apple’s subscription management tools. Canceling renewal does not automatically produce a refund; the current service term remains in effect under the order unless it is refunded.

3.3If your plan includes lifetime Pro after meeting cumulative subscription conditions, the conditions, platforms, and scope are those displayed when you purchase. Benefits and credit toward lifetime Pro associated with a refunded order are adjusted to reflect that refund, without affecting benefits from other independently valid orders.

3.4When Pro+ expires, an account with valid lifetime Pro benefits becomes Pro; otherwise it becomes Basic. Cloud Libraries exceeding the Library count allowance are locked and cannot be edited, but can be exported as Zip files and converted to local Libraries. An unlocked cloud Library that exceeds its entry allowance cannot accept new entries, while existing entries remain editable. Other allowances follow the membership benefits page.

4. Refunds and purchase channels

Website purchases are eligible for a full refund requested within 7 days of payment, with no refund handling fee. Membership expiry or non-renewal alone will not cause your cloud Libraries to be deleted.

4.1For a website purchase, request a full refund at support@tominlab.com within 7 days from successful payment. Please provide an order number or other verifiable purchase information. If the order is linked to an email address, we recommend sending your refund request from that address to help us verify the purchase. We do not charge a refund handling fee. The time for funds to reach you depends on the payment channel’s processing.

4.2For in-app purchases through platforms such as the Apple App Store or Mac App Store, apply to the purchase platform under its rules and applicable law. For purchases through Digitalychee or other resellers, distributors, or channels, contact that channel under its rules and applicable law. We can assist with order or license verification.

4.3When a refund takes effect, the Pro+ entitlement granted by the refunded order ends immediately rather than continuing to its originally scheduled expiry. For third-party refunds, we process this after receiving a valid refund notification. A refunded lifetime license or other product has its associated license or benefits revoked. Other independently valid orders and their benefits are handled under their own terms.

4.4If a refund results in a downgrade, cloud Libraries become subject to the downgraded features and allowances and are not directly deleted because of the refund. The 7-day period does not restrict statutory refund or other remedies where services fail to meet the agreement or we fail to perform our obligations.

5. Documents, synchronization, and retention

5.1Rights in your works and stored content remain with you or the relevant rights holders. By using cloud services, you authorize processing only as necessary for storage, synchronization, backup, security maintenance, and support you request. You do not grant us the right to publish, sell, or use that content for AI training.

5.2Document content in local Libraries is stored on your device and is not automatically uploaded as cloud documents merely because you use a local Library. Actions you initiate, such as moving to a cloud Library, submitting feedback attachments, or authorizing external tools, follow their respective feature descriptions. Online processing of account settings, writing statistics, and similar data is explained separately in the Privacy Policy.

5.3Cloud synchronization requires an available network, account permissions, and service availability. Check synchronization results and status before switching devices, and regularly export or back up important works to a location you control. Synchronization and server backups do not replace an independent copy of important files. Related risks and liability are addressed in Section 8.

5.4We will not delete your cloud Libraries solely because your membership expires, you stop renewing, or you remain inactive for a long time. Downgrades, usage restrictions, and export access after expiry follow Section 3.

5.5Current document content is distinct from historical snapshots, writing-process records, and rolling backups. Historical records and backups follow the periods, allowances, and applicable transition arrangements described in the relevant membership plan and may be removed when those periods expire. This does not change the preceding retention principle for current cloud Library content.

5.6If we need to change cloud data retention rules in the future, we will explain the reasons, scope, effective date, and export methods in advance through reasonable channels such as in-app notices and registered email, provide reasonable transition and export periods, and follow legally required procedures. Changes will not retrospectively reduce purchased service rights that remain unfulfilled.

5.7If we discontinue cloud storage services, we will announce and notify users in advance as required by law, provide a reasonable export period no shorter than required by applicable law, and address paid services not yet delivered. These arrangements are not a commitment to provide cloud storage indefinitely.

5.8Documents, Libraries, or accounts you choose to delete are handled according to the relevant operation and applicable law. Export what you need before confirming an irreversible deletion. Records required by law are retained only within the legally required scope and period.

6. Lawful use and enforcement

6.1You must not use the services for unlawful conduct, infringe intellectual property or privacy, distribute unlawful content, compromise system security, or bypass license and payment restrictions. These Terms do not impose additional restrictions on ordinary literary creation, lawful reference materials, or official export and open-interface features.

6.2We may take necessary measures according to the nature and impact of unlawful conduct or a breach, including warnings, feature restrictions, or service suspension. Access to unlawful content may be restricted or the content deleted according to law. Where legally required, or where serious unlawful conduct makes termination necessary, relevant cloud Libraries may be deleted, with necessary records retained as required by law.

6.3This section does not grant us the right to arbitrarily view, review, or delete your document content. Processing of document content is limited to the purposes and necessary scope described in these Terms and the Privacy Policy. Deletion of content or Libraries under this section is limited to the circumstances for addressing unlawful conduct specified in Section 6.2.

6.4Unless advance notice is inappropriate due to an urgent security incident, legal requirement, or competent authority’s instruction, we will explain the reason and provide contact and appeal channels.

7. Privacy and external tools

7.1Personal information is governed by the WonderPen Privacy Policy and the website policy where expressly applicable. Accepting these Terms does not replace consent that must be obtained separately under law.

7.2If you choose to open third-party websites, use third-party services in a web panel, or authorize external tools to access data through an open interface, that third party’s processing is governed by its own rules. Such external services initiated by you are not AI services provided by us. Providing general web or interface capabilities does not cause us to automatically send your works to third parties.

7.3You may request account deletion in the app or website’s account settings, or contact support@tominlab.com for assistance. Before deletion, export your data, consider the impact on linked services and benefits, and separately cancel auto-renewal with Apple or another purchase platform.

8. Service assurances and limitations of liability

Please pay particular attention to the scope of service assurances, force majeure, recoverable losses, and mitigation duties in this section. Contact support if you need an explanation.

8.1We provide services according to the product descriptions, order, and these Terms, using reasonable technical and organizational measures to maintain security and normal operation. Unless expressly agreed otherwise, we do not guarantee uninterrupted or entirely error-free service, compatibility with every device or third-party environment, or particular results or commercial returns that we have not expressly promised. Services remain subject to statutory and expressly agreed quality requirements.

8.2We may temporarily interrupt or restrict relevant features as necessary for maintenance, upgrades, or security response, reasonably managing the scope and duration of the impact. We will give reasonable advance notice of planned maintenance affecting normal use. Where an emergency prevents advance notice, we will explain as soon as circumstances permit. We will take reasonable steps to investigate and restore services following a failure; unless expressly agreed otherwise, we do not guarantee a fixed completion time for repairs. Undelivered paid services are handled under the relevant provisions of these Terms and applicable law.

8.3Where performance is prevented by force majeure that is unforeseeable, unavoidable, and insurmountable, liability may be partly or wholly excused according to its actual impact, to the extent permitted by law. The affected party must promptly notify the other party and provide supporting evidence within a reasonable period. Whether a cyberattack, communications failure, or other event qualifies for force majeure or another statutory reduction or exemption is determined by the facts and applicable law. Force majeure arising after performance is already delayed is handled according to law.

8.4Losses caused by your equipment failure, failure to safeguard credentials, incorrect operations, or unauthorized client modifications are borne by the responsible party if they are not caused by our unlawful conduct or breach. The same principle applies to losses caused by third-party services you independently choose. This provision does not apply to third-party services we use to fulfill our obligations under these Terms.

8.5If we are legally liable for damages for breach of contract, compensation is limited to legally established losses causally connected to that breach and may not exceed losses that were foreseen or should have been foreseen at the time of contracting as a possible consequence of the breach. Claims unrelated to the breach, outside that foreseeable scope, or lacking a factual basis fall outside that compensation. A user's own estimate of a work's value, expected income, or commercial opportunity does not by itself establish the amount payable. Lost profits that are legally recoverable are determined according to law.

8.6If you discover a service incident or potential loss, promptly contact us and take reasonable steps to prevent further loss. We are not liable, as provided by law, for additional losses resulting from a failure to take appropriate mitigating steps. If you are also at fault in causing the loss, our liability is reduced accordingly under law. Whether reasonable backup, credential protection, or synchronization checks were taken is assessed in light of the circumstances and their causal connection to the loss.

8.7These limitations do not apply to personal injury, property damage caused by our intentional misconduct or gross negligence, or other liability that cannot lawfully be excluded or limited. They do not affect statutory remedies such as refunds or repairs. Mandatory legal provisions prevail.

9. Updates, disputes, and contact

9.1We will publish revised Terms and their update date. Major changes concerning fees, purchased rights, retention, or dispute resolution will be communicated reasonably and prominently before taking effect, and further agreement obtained where legally required. You do not have to delete your account immediately to object to a change.

9.2These Terms are governed by the laws of mainland China without affecting other mandatory protections applicable by law. The parties may first seek an amicable resolution; if that fails, either party may bring proceedings before a people’s court with jurisdiction under law.

9.3If a provision is invalid or unenforceable, the remaining provisions remain effective. For questions about services, refunds, data export, or disputes, contact support@tominlab.com.
