Terms of Service

1. Agreement and Acceptance

These Terms of Service ("Terms") form a binding legal agreement between you ("you", "User", "Customer") and Dusky ("Dusky", "we", "us", "our") and govern your access to and use of the Dusky website at askdusky.com, our web application, desktop applications, APIs, integrations, documentation, and all related services (collectively, the "Service"). By creating an account, ticking the acceptance checkbox, clicking "I agree", signing in with a third-party identity provider, or otherwise accessing or using the Service, you agree to be bound by these Terms and by our Privacy Policy, which is incorporated by reference. If you do not agree, you must not use the Service.

If you are entering into these Terms on behalf of a company, employer, or other legal entity, "you" refers to that entity, and you represent that you have authority to bind it. Where a separately signed agreement, order form, or data processing agreement exists between you and Dusky, that agreement controls to the extent of any conflict.

2. Eligibility and Authority

You must be at least 16 years old, or the age of digital consent in your jurisdiction if higher, and legally capable of forming a binding contract. The Service is not available to anyone previously suspended or removed by us, or to anyone barred from receiving services under applicable law. You must provide accurate registration information and keep it current.

3. Description of the Service

Dusky is an AI-assisted email assistant. With your explicit authorization, Dusky connects to one or more third-party mailboxes (for example Gmail via Google OAuth) to:

• list, search, and display messages from your inbox and sent mail;
• summarize, triage, and prioritize messages;
• answer questions about your mailbox in a chat interface;
• draft replies and new messages for your review;
• send messages that you explicitly confirm;
• run saved instructions ("Automations") on demand or on a schedule to produce reports and digests, including downloadable PDF exports;
• store preferences and memories you provide so future output better matches your needs.

Dusky is a productivity tool. It is not a legal, medical, financial, tax, immigration, employment, or other professional advisory service, and its output must not be treated as professional advice.

4. Accounts, Credentials, and Security

You are responsible for safeguarding your account credentials, any device on which you remain signed in, and all activity occurring under your account. The "remember this device" option keeps a session active on that device until you sign out; do not use it on shared or public machines. You must notify us promptly at support@myvoidline.com of any suspected unauthorized access. We are not liable for losses caused by unauthorized use of your account where that use did not result from our failure to meet our own security obligations.

Accounts are for a single identified individual unless you hold a plan that expressly permits additional seats. You may not share, sell, resell, or transfer account access.

5. Connected Third-Party Accounts (Gmail and Others)

When you connect a third-party account, you grant Dusky authorization, through the provider's OAuth flow and within the scopes you approve, to access, retrieve, store, process, and transmit data from that account solely to provide the Service to you. You represent that you are the lawful account holder or are otherwise authorized to grant this access, including where the mailbox belongs to an employer or client, and that doing so does not breach any policy, contract, or law applicable to you.

Your use of any third-party service remains governed by that provider's own terms and policies. Providers may change, restrict, throttle, or revoke API access at any time, which may interrupt or permanently impair parts of the Service. You may revoke Dusky's access at any time from within the Service or from the provider's own security settings; doing so will disable features that depend on it.

6. Multiple Mailboxes

You may connect multiple mailboxes to a single Dusky account. Each connected mailbox is subject to the same authorization, security, and acceptable-use requirements. You are responsible for ensuring you have the right to connect each mailbox and for keeping content from separate mailboxes appropriately segregated where you are required to do so (for example, by an employer or a client confidentiality obligation). Automations, chat, and reports may operate across all connected mailboxes unless you scope them otherwise.

7. Sending Email and Human Confirmation

Dusky prepares drafts. No message is transmitted from a connected mailbox unless you take an affirmative action to send it in a review-and-confirm step. Once sent, a message is delivered by your email provider and cannot be recalled by us. You are the sender of record and are solely responsible for the recipients, content, attachments, timing, legal compliance, and consequences of every message you send through the Service. You must review AI-generated content for accuracy, confidentiality, tone, and legal exposure before sending.

8. AI Output and Its Limits

The Service uses large language models and other machine learning systems supplied by us and by third parties to generate summaries, drafts, classifications, priorities, and reports ("AI Output"). AI Output is probabilistic. It may be inaccurate, incomplete, outdated, biased, offensive, or fabricated ("hallucinated"), may misclassify the importance of a message, may omit a message entirely, and may misinterpret your instructions.

You must not rely on the Service as the sole means of monitoring a mailbox where a missed message could cause harm, loss, or a missed deadline. You are solely responsible for reviewing, editing, and approving AI Output before sending, publishing, filing, or acting on it. Identical or similar output may be generated for other users; AI Output is not represented to be unique. To the extent AI Output is capable of ownership, and subject to applicable law and third-party model provider terms, as between you and us you own the AI Output generated for you.

9. Automations, Scheduling, and Reports

Automations are instructions you save so the Service can execute them on demand or on a recurring schedule in your configured timezone. You are responsible for the content of your instructions and for the results they produce. Scheduled execution is best-effort: runs may be delayed, skipped, retried, deduplicated, truncated, or fail due to provider rate limits, model availability, maintenance, or your own quota. We do not guarantee that any run will occur at an exact time or at all, and we are not liable for consequences of a delayed, failed, or missed run.

Reports and PDF exports are generated from the state of your mailbox at run time and may be incomplete. We may retain run history and report content in your account so you can review it; you may delete runs and reports at any time.

10. Memory, Feedback, and Model Improvement

The Service supports several distinct mechanisms for improving output quality, each governed by your own settings:

• Automation context. Purpose, audience, tone, and output-style fields you supply are stored with the automation and used in prompts.
• Private memory. Preferences and notes stored to your account only, visible only to you, and used only in your own runs. You can view, edit, pin, and delete these at any time.
• Feedback. Thumbs up/down and accompanying notes you submit on a report.
• Community learnings. An optional, off-by-default-until-you-enable-it setting under which anonymized, generalized lessons derived from your feedback may improve the Service for other users. You control this with the sharing toggle in Settings, and you can turn it off at any time; turning it off stops future contributions.

We do not use the contents of your emails to train general-purpose or foundation AI models, and we contractually require our model providers not to do so on data we send them. See the Privacy Policy for detail.

11. Notifications and Communications

You may enable in-app, browser, desktop, and email notifications. Browser and desktop notifications require operating-system and browser permissions that you control and can revoke. Notification delivery is best-effort and may be delayed or suppressed by your device, browser, network, or email provider. You may disable optional notifications at any time in Settings, but you cannot opt out of essential transactional and security messages while you maintain an account.

12. Desktop Applications

We offer downloadable desktop applications for macOS and Windows. Desktop builds are licensed, not sold, under the same limited license granted in these Terms and may include an automatic update mechanism you consent to by installing. Operating-system gatekeeping features may display warnings for applications distributed outside an app store; instructions we provide for proceeding are offered as-is, and you are responsible for deciding whether to run any software on your device. Desktop builds may lag behind the web application in features and fixes.

13. Acceptable Use

You agree not to, and not to permit anyone else to:

• use the Service to send spam, bulk unsolicited mail, phishing, malware, scams, or deceptive content;
• harass, threaten, defame, impersonate, or infringe the rights of any person;
• violate any law or regulation, including intellectual property, privacy, data protection, export control, wiretapping, and anti-spam laws (CAN-SPAM, CASL, GDPR/UK GDPR, ePrivacy, and equivalents);
• access a mailbox you are not authorized to access, or use the Service for covert surveillance of another person;
• process special-category or highly sensitive data (health records, government identifiers, payment card data, or similar) except where you have a lawful basis and appropriate safeguards, and at your own risk;
• reverse engineer, decompile, scrape, benchmark for publication, or attempt to extract source code, model weights, or system prompts;
• probe, scan, overload, circumvent rate limits, or otherwise interfere with the security or integrity of the Service;
• use the Service to build a competing product, or to generate training data for a competing model;
• use the Service to make automated decisions producing legal or similarly significant effects on individuals without meaningful human review;
• remove or obscure any proprietary notice, or misrepresent your affiliation with Dusky.

We may investigate suspected violations and may suspend or terminate access immediately, with or without notice, to protect the Service, other users, or third parties.

14. Anti-Spam and Bulk Sending

You are the sender of every message dispatched through the Service. You are responsible for maintaining a lawful basis or consent for contacting each recipient, for honoring unsubscribe and opt-out requests promptly, for accurate sender identification and subject lines, and for including any disclosures your jurisdiction requires. The Service is not designed or licensed as a bulk marketing platform, and using it as one may result in immediate suspension.

15. Your Content and License

You retain all rights in the email content, prompts, instructions, memories, feedback, files, and other material you submit or that Dusky accesses on your behalf ("Your Content"). You grant Dusky a worldwide, non-exclusive, royalty-free, sublicensable (only to subprocessors acting on our behalf) license to host, store, copy, transmit, display, process, and create derivative works of Your Content solely to operate, secure, support, maintain, and improve the Service for you and to comply with law. This license ends when Your Content is deleted, subject to routine backup retention and legal-hold requirements. We do not sell Your Content.

You represent that you have all rights necessary to grant this license and that Your Content does not violate law or third-party rights.

16. Fees, Plans, Trials, and Renewals

Some features may be free and others paid. Prices, included usage, billing frequency, and any trial terms are disclosed at the point of purchase. Unless stated otherwise: subscriptions renew automatically for successive periods at the then-current price until cancelled; you authorize us and our payment processors to charge your payment method on each renewal; prices are exclusive of taxes, and you are responsible for all applicable taxes, duties, and withholdings; failed payments may result in downgrade or suspension after a grace period. We may change pricing with reasonable prior notice effective at your next renewal.

17. Refunds and Cancellation

You may cancel at any time, effective at the end of the current billing period, after which you retain access until that period ends. Except where mandatory consumer law requires otherwise, fees already paid are non-refundable and we do not provide pro-rated refunds for partial periods, unused capacity, or downgrades. Consumers in the EEA and UK retain any applicable statutory withdrawal rights; by requesting immediate access to a paid digital service you may be asked to acknowledge that the withdrawal right ends once performance begins.

18. Usage Limits and Fair Use

The Service is subject to reasonable technical limits, including message-fetch volume, model token usage, automation frequency, storage, and API request rates. We may apply or adjust these limits to protect availability, and may throttle, queue, or decline requests that are excessive relative to normal individual use. Persistent excessive use may require an upgraded plan.

19. Beta and Experimental Features

Features labelled beta, preview, early access, or experimental are provided for evaluation, may be changed or withdrawn at any time, may be less reliable, and are excluded from any service commitment or warranty to the maximum extent permitted by law.

20. Intellectual Property

The Service, including all software, interfaces, models, prompts, workflows, documentation, trademarks, logos, and the "Dusky" name, is owned by Dusky or its licensors and protected by intellectual property law. Subject to your compliance with these Terms and payment of applicable fees, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to access and use the Service for your internal purposes. All rights not expressly granted are reserved. No trademark license is granted.

21. Feedback

If you send us suggestions, ideas, or feedback about the Service, you grant Dusky a perpetual, irrevocable, worldwide, royalty-free license to use, modify, and commercialize it without restriction, attribution, or compensation.

22. Third-Party Services

The Service interoperates with third-party providers, including Google/Gmail, cloud hosting, database and authentication providers, AI model providers, email delivery infrastructure, and payment processors. We are not responsible for third-party services, do not warrant their availability, accuracy, pricing, or security, and are not liable for their acts or omissions. Changes by a provider may degrade or remove functionality without notice.

23. Privacy and Data Protection

Our handling of personal data is described in the Privacy Policy. Where you use the Service to process personal data of others and applicable data protection law makes you the controller and us the processor, our processing is limited to your documented instructions as expressed through your use of the Service; a data processing agreement is available on request at support@myvoidline.com.

24. Confidentiality

Each party will protect the other's non-public information disclosed in connection with the Service with at least reasonable care and use it only for purposes of these Terms. This does not apply to information that is public through no fault of the recipient, independently developed, rightfully received from a third party, or required to be disclosed by law (with notice where legally permitted).

25. Service Availability and Changes

We aim for high availability but do not guarantee uninterrupted access unless a separate written service level agreement applies. We may modify, add, or remove features, and may perform scheduled or emergency maintenance. We will use reasonable efforts to give notice of material adverse changes to core functionality. We may discontinue the Service entirely with reasonable notice, and in that case will offer a pro-rated refund of prepaid, unused fees.

26. Suspension and Termination

You may stop using the Service and delete your account at any time. We may suspend or terminate your access: for breach of these Terms; for non-payment; for conduct posing a security, legal, or reputational risk; if required by a third-party provider or by law; or, for free accounts, with reasonable notice for any reason. Upon termination your license ends immediately. Sections that by their nature survive termination will survive, including content ownership, fees accrued, confidentiality, disclaimers, limitations of liability, indemnification, and dispute resolution.

27. Data Export and Deletion on Termination

Before or promptly after termination you may export your data using in-product export features. Following account deletion we will delete or irreversibly anonymize your personal data within a reasonable period, other than data we must retain for legal, accounting, security, or dispute-resolution purposes, and residual copies in encrypted backups that expire on our normal backup cycle. Anonymized community learnings that no longer identify you may persist.

28. Disclaimer of Warranties

The service is provided "as is" and "as available" without warranties of any kind, whether express, implied, statutory, or otherwise, including implied warranties of merchantability, fitness for a particular purpose, title, quiet enjoyment, non-infringement, and any warranties arising from course of dealing or usage of trade. Dusky does not warrant that the service will be uninterrupted, timely, secure, or error-free; that any defect will be corrected; that any message will be fetched, classified, delivered, or surfaced; or that AI output will be accurate, complete, or fit for any purpose. Some jurisdictions do not allow the exclusion of implied warranties, so parts of this section may not apply to you, and nothing here limits non-excludable statutory consumer guarantees.

29. Limitation of Liability

To the maximum extent permitted by law, in no event will Dusky, its affiliates, officers, directors, employees, agents, suppliers, or licensors be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, revenue, data, goodwill, business opportunity, or anticipated savings, or for any missed, delayed, misclassified, or erroneously sent email, or for any reliance on AI output, arising out of or related to these terms or the service, whether in contract, tort, strict liability, or any other legal theory, and whether or not advised of the possibility of such damages. Dusky's total cumulative liability for all claims arising out of or related to these terms or the service will not exceed the greater of (a) the total amount you paid Dusky in the twelve (12) months preceding the event giving rise to the claim, or (b) one hundred US dollars (USD 100).

Nothing in these Terms excludes or limits liability for fraud, fraudulent misrepresentation, death or personal injury caused by negligence, or any other liability that cannot lawfully be excluded.

30. Indemnification

You agree to defend, indemnify, and hold harmless Dusky and its affiliates, officers, employees, and agents from and against any third-party claims, damages, liabilities, penalties, costs, and expenses (including reasonable attorneys' fees) arising out of or related to (a) your use of the Service; (b) Your Content; (c) any email sent or caused to be sent through your account; (d) your connection of any mailbox you were not authorized to connect; (e) your violation of these Terms; or (f) your violation of any law or third-party right. We will notify you of the claim, give you control of the defense (subject to our right to participate with our own counsel), and cooperate reasonably at your expense. You may not settle any claim in a way that imposes liability or admission on us without our written consent.

31. Export Controls and Sanctions

You represent that you are not located in, and are not a national or resident of, a country subject to comprehensive sanctions, and that you are not on any restricted party list. You will not export, re-export, or make the Service available in violation of applicable export control or sanctions laws.

32. Government and Regulated Users

The Service is commercial computer software. Use by any government entity is subject to these Terms, and no additional government rights are granted. If you are subject to sector-specific regulation (for example healthcare, financial services, or legal professional privilege), you are responsible for determining whether your use is permitted; we do not represent that the Service is compliant with HIPAA, PCI-DSS, or similar frameworks unless expressly agreed in writing.

33. Force Majeure

Neither party is liable for failure or delay in performance caused by events beyond its reasonable control, including acts of God, war, terrorism, civil unrest, labor disputes, epidemics, government action, internet or utility failure, cyberattack, or failure of a third-party provider.

34. Governing Law

These Terms and any dispute arising from them are governed by the laws of the jurisdiction in which Dusky is established, without regard to conflict-of-laws rules and excluding the UN Convention on Contracts for the International Sale of Goods. Where mandatory consumer protection law of your country of residence gives you greater rights, those rights are unaffected.

35. Dispute Resolution and Arbitration

Before filing a claim, you agree to try to resolve the dispute informally by contacting support@myvoidline.com and allowing thirty (30) days for good-faith resolution. If unresolved, the parties submit to the exclusive jurisdiction of the competent courts of the jurisdiction in which Dusky is established, except that either party may seek injunctive or equitable relief in any court of competent jurisdiction to protect intellectual property or confidential information. To the maximum extent permitted by law, claims must be brought individually and not as a class, consolidated, or representative action, and any claim must be filed within one (1) year after it arises. Consumers retain any non-waivable right to bring proceedings in their local courts or to use an applicable alternative dispute resolution scheme.

36. Changes to These Terms

We may update these Terms. For material changes we will give reasonable advance notice by email or in-product notice, and the updated Terms take effect on the stated effective date. Your continued use after that date constitutes acceptance. If you do not accept, you must stop using the Service and may cancel; for paid plans you may request a pro-rated refund of prepaid, unused fees for the remainder of the term.

37. Assignment

You may not assign or transfer these Terms without our prior written consent. We may assign these Terms to an affiliate or in connection with a merger, acquisition, reorganization, or sale of substantially all assets. These Terms bind permitted successors and assigns.

38. Notices

We may send notices to the email address associated with your account or display them in-product; such notices are deemed received when sent or displayed. You must send legal notices to support@myvoidline.com.

39. Miscellaneous

These Terms, together with the Privacy Policy and any order form or written agreement between us, constitute the entire agreement and supersede all prior understandings on their subject matter. If any provision is held unenforceable, it will be modified to the minimum extent necessary and the remainder will stay in effect. No waiver is effective unless in writing, and failure to enforce a provision is not a waiver. There are no third-party beneficiaries. The parties are independent contractors. Headings are for convenience only. These Terms are drafted in English; any translation is for convenience and the English version controls.
