4. The Service and AI-Assisted Outputs
Sharpen is a software-as-a-service product that helps users improve prompts through AI-assisted suggestions, rewrites, workspace history, and related account features.
Sharpen uses artificial intelligence technologies to generate, assist with, or surface suggestions, rewrites, and related outputs.
AI-assisted outputs may be inaccurate, incomplete, misleading, non-unique, inappropriate for your intended use, or similar to content generated for or by others.
You are solely responsible for reviewing, validating, editing, and deciding whether to use any output generated or surfaced by Sharpen.
Sharpen is not a substitute for professional judgment and must not be relied on for medical, legal, financial, employment, housing, insurance, credit, safety-critical, or other high-stakes decision-making.
We do not guarantee that any output is correct, lawful, original, non-infringing, suitable for your purpose, or free from third-party rights.
5. Your Content, Outputs, and Our Limited License
You retain ownership of the prompts, text, inputs, files, materials, and other content you submit to Sharpen, as well as the outputs generated for you through the service, to the extent permitted by applicable law.
You grant us a non-exclusive, worldwide, royalty-free license to host, store, reproduce, transmit, display, adapt, analyze, and otherwise use your inputs and outputs as reasonably necessary to operate, maintain, secure, support, improve, and provide Sharpen, and to comply with law.
You represent and warrant that you have all rights necessary to submit your content to Sharpen and to grant the rights described in these Terms.
You may use outputs commercially at your own risk. You remain solely responsible for ensuring that your use of any input or output complies with applicable law, third-party rights, and your own contractual obligations.
Our handling of personal data is described in our Privacy Policy. These Terms do not replace our Privacy Policy or any applicable data processing agreement.
6. Privacy and Data Protection
Your use of Sharpen may involve the processing of personal data. We process personal data as described in our Privacy Policy, available at https://sharpen.ink/privacy.
If you use Sharpen for business purposes and submit personal data for which you or your organization are the controller, additional data processing terms may apply.
You must not submit sensitive personal data, confidential third-party information, regulated data, or personal data that you are not authorized to provide unless you have a lawful basis and all required permissions to do so.
You are responsible for reviewing and configuring your use of Sharpen in a way that complies with the privacy, confidentiality, and data-protection obligations that apply to you.

You may not use Sharpen to break the law, infringe intellectual property or privacy rights, harass or abuse others, distribute malware, attempt unauthorized access, interfere with the service, evade quotas or billing controls, or misuse the service.
You may not use Sharpen in a manner that creates a material security risk, legal risk, platform abuse risk, or risk of harm to Sharpen, other users, or third parties.
You may not reverse engineer, scrape, crawl, copy, benchmark, or attempt to extract the underlying systems, prompts, models, infrastructure, or non-public functionality of Sharpen except to the extent such restriction is prohibited by applicable law.
You may not resell, lease, sublicense, white-label, or provide third parties with access to the Sharpen service itself without our prior written permission.
This restriction does not prevent you from using generated outputs in your own downstream materials, subject to these Terms.

9. Paid Plans, Subscriptions, and Usage Credits
Sharpen may offer paid subscriptions, usage credits, quotas, or other paid features.
Prices, features, quotas, limits, and plan structures may change over time. Changes to paid plans, prices, quotas, or credit structures apply prospectively unless otherwise stated and permitted by applicable law.
Unless otherwise stated at the time of purchase, subscriptions may renew automatically until canceled.
Purchased usage credits are non-transferable, non-refundable, and not redeemable for cash except where required by applicable law.
Purchased usage credits do not expire unless expiration is stated at the time of purchase, required by law, or your account is terminated under these Terms.
If we terminate your account for material breach, misuse, fraud, unlawful activity, or violation of these Terms, unused credits may be forfeited where permitted by law.
If we discontinue the service or terminate your account without cause, we will provide a reasonable opportunity to use unused paid credits, provide an alternative remedy, or issue a refund where required by applicable law.
Payments may be processed by third-party payment providers such as Stripe. Your use of those payment services may also be subject to their own terms and policies.
Prices may exclude applicable taxes, VAT, GST, sales tax, duties, or similar charges unless expressly stated otherwise. You are responsible for applicable taxes where required by law.
10. Refunds, Cancellation, and Consumer Withdrawal Rights
Except where required by applicable law or expressly stated at the time of purchase, purchases are non-refundable.
You may cancel a subscription at any time, but cancellation does not retroactively entitle you to refunds except where required by law.
If you are a consumer, you may have statutory cancellation or withdrawal rights, including rights that cannot be waived by contract.
Where applicable law allows, and where you request immediate access to paid digital services or digital content before the end of a withdrawal period, we may ask you to expressly consent to immediate performance and acknowledge any resulting loss or limitation of withdrawal rights.
Nothing in these Terms limits or excludes any refund, cancellation, withdrawal, or statutory remedy that cannot be limited or excluded under applicable consumer law.

We may limit the availability of Sharpen, or any feature, plan, payment method, credit structure, or account access, in any country, region, or jurisdiction at any time where we consider it necessary or appropriate.
We may change, suspend, discontinue, or limit features, quotas, pricing, plans, credit structures, or other parts of Sharpen at any time.
For material changes that negatively affect an active paid subscription, we will provide reasonable notice where required by law or commercially practicable.

13. Suspension and Termination
We may suspend, restrict, or terminate your access to Sharpen at any time, with or without notice where reasonably necessary, including for abuse, misuse, security risk, suspected unlawful activity, payment failure, sanctions risk, violation of these Terms, or risk of harm to Sharpen, users, or third parties.
You may stop using Sharpen at any time. You may also request account deletion by contacting support@hannlabs.com, subject to our legal, security, billing, and legitimate business retention requirements.
You may appeal a suspension or termination by contacting support@hannlabs.com, but we retain discretion over account access and reinstatement decisions, subject to applicable law.
After termination, we may delete stored prompts, outputs, workspace data, and account data after a reasonable retention period unless we are required or permitted by law to retain it longer.
Sections that by their nature should survive termination will survive, including provisions relating to intellectual property, payment obligations, disclaimers, limitation of liability, indemnity, disputes, and governing law.
14. Disclaimer of Warranties
To the maximum extent permitted by law, Sharpen is provided on an “as is” and “as available” basis without warranties of any kind, whether express, implied, statutory, or otherwise.
To the maximum extent permitted by law, we disclaim all warranties, including implied warranties of merchantability, fitness for a particular purpose, non-infringement, accuracy, availability, reliability, security, uninterrupted operation, and error-free performance.
We do not warrant that Sharpen or any output will meet your requirements, be accurate, be available at all times, be secure, be free of harmful components, or produce any particular result.
If you are a consumer, nothing in these Terms limits or excludes any rights, guarantees, remedies, or protections that cannot be limited or excluded under applicable consumer law.
15. Limitation of Liability
To the maximum extent permitted by law, Sharpen and its provider will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, revenues, goodwill, data, business opportunities, or anticipated savings arising from or related to your use of or inability to use Sharpen.
To the maximum extent permitted by law, our aggregate liability for all claims arising out of or relating to Sharpen or these Terms will not exceed the greater of: (a) the amount you paid us for Sharpen in the 12 months before the event giving rise to the claim; or (b) EUR 100.
The limitations in this section apply whether a claim is based on contract, tort, negligence, strict liability, statute, or any other legal theory, even if we have been advised of the possibility of such damages.
Nothing in these Terms excludes or limits liability that cannot be excluded or limited under applicable law, including liability for fraud, intentional misconduct, gross negligence, death or personal injury caused by negligence, or mandatory consumer protections.
16. Business-User Indemnity
If you use Sharpen on behalf of a business, organization, or for commercial organizational purposes, you will defend, indemnify, and hold harmless Sharpen, its provider, affiliates, contractors, licensors, and service providers from and against third-party claims, liabilities, damages, losses, and expenses, including reasonable legal fees, arising out of or related to your content, your outputs, your misuse of the service, your violation of these Terms, or your violation of applicable law or third-party rights.
This indemnity does not apply to consumers acting outside their trade, business, craft, or profession.
17. Governing Law, Disputes, and Consumer Rights
These Terms are governed by the laws of Portugal, without regard to conflict-of-laws principles, except to the extent mandatory consumer protection law provides otherwise.
If you are using Sharpen as a business user, any dispute arising out of or relating to these Terms or the service will be resolved by binding arbitration seated in Lisbon, Portugal, before a single arbitrator, except that either party may seek interim, injunctive, or equitable relief from a competent court where necessary.
To the maximum extent permitted by law, business-user claims must be brought only in an individual capacity and not as part of a class, collective, consolidated, or representative proceeding.
If you are a consumer, nothing in these Terms deprives you of mandatory statutory rights, including any right to bring claims before competent courts or use alternative dispute resolution channels where those rights cannot lawfully be waived.
18. Updates to These Terms
We may update these Terms from time to time.
Updated Terms become effective when posted or on the date stated in the update, except where applicable law requires a different process.
Your continued use of Sharpen after updated Terms take effect constitutes acceptance of the updated Terms, except where applicable law requires your express consent or a different process.
