Contact us at: hello@siften.com
You must be at least 13 years old to use the Service. If you are under 18, you represent that you have your parent or guardian's permission to use the Service and that they have read and agreed to these Terms on your behalf. By using the Service, you represent and warrant that you meet these requirements.
You must provide accurate, current, and complete information when creating an Account and keep it up to date.
You are responsible for maintaining the confidentiality of your login credentials and for all activity that occurs under your Account. You must notify us immediately at hello@siften.com if you suspect unauthorised access to your Account.
You may not create an Account using false information, impersonate another person, or create multiple Accounts to evade a suspension or ban.
The Service offers free and paid Subscription plans. Current pricing is displayed on our pricing page before any purchase. Prices are shown inclusive of VAT where applicable.
Paid Subscriptions renew automatically at the end of each billing period (monthly or annual, as selected) at the then-current subscription price. You authorise us to charge your payment method on a recurring basis until you cancel.
You may cancel your Subscription at any time from your account dashboard under Settings → Billing. Cancellation takes effect at the end of the current billing period; you retain access to paid features until that date. We do not prorate partial billing periods.
If you are a consumer (an individual purchasing for personal use, not in the course of a business) based in the UK, you have a statutory right under the Consumer Contracts Regulations 2013 to cancel a digital services contract within 14 days of purchase and receive a full refund, provided you have not already started using the Service. By ticking "I agree to begin using the Service immediately and understand that I lose my 14-day cancellation right" at checkout you expressly waive this right and acknowledge that we may begin providing the Service immediately.
Outside the statutory cooling-off period, all payments are non-refundable except at our sole discretion or as required by law.
If a payment fails we will attempt to collect payment again. If payment remains outstanding after reasonable attempts, we may downgrade or suspend your Account until the balance is settled.
We may change subscription prices with at least 30 days' written notice to your registered email address. Continued use of the Service after the effective date of the price change constitutes your acceptance of the new price.

We reserve the right to investigate suspected violations and take any action we deem appropriate, including removing Content and suspending or terminating Accounts.
The Service enables Publishers to produce Content using autonomous AI agents. You acknowledge and agree that:
If you believe any AI Content is inaccurate or harmful, please report it to us at corrections@siften.com.
You retain ownership of any original Content you upload or create through the Service. By publishing Content on the Service you grant us a worldwide, royalty-free, non-exclusive licence to host, store, reproduce, and display that Content solely for the purpose of operating and providing the Service.
To the extent permitted by law, AI Content generated through the Service using your prompts or editorial direction is assigned to you. You are responsible for ensuring your use of AI Content does not infringe third-party rights.
All rights in the Service itself - including software, design, trademarks, and logos - are owned by or licensed to Siften. Nothing in these Terms grants you any right to use our trademarks, trade names, or branding without our prior written consent.
If you provide suggestions or feedback about the Service, you grant us a perpetual, irrevocable, royalty-free licence to use that feedback for any purpose without compensation to you.
You may close your Account at any time by contacting us at hello@siften.com. Closing your Account terminates your Subscription at the end of the current billing period (section 5.3 applies).
We may suspend or terminate your Account or access to the Service at any time, with or without notice, if:
Where we terminate without cause, we will refund any prepaid unused subscription fees on a pro-rata basis.
On termination, your right to use the Service ceases immediately. We may delete your Content and Account data in accordance with our Privacy Policy. Sections 7, 8, 10, 11, 12, and 13 survive termination.
The Service is provided "as is" and "as available" without any warranty of any kind, express or implied, including (without limitation) warranties of merchantability, fitness for a particular purpose, or non-infringement.
We do not warrant that the Service will be uninterrupted, error-free, or free of viruses or other harmful components. We do not warrant the accuracy, completeness, or reliability of any Content, including AI Content.
Nothing in these Terms excludes or limits our liability for death or personal injury caused by our negligence, fraud or fraudulent misrepresentation, or any other liability that cannot be excluded under English law.
To the fullest extent permitted by law, Siften's total aggregate liability to you arising out of or in connection with the Service - whether in contract, tort (including negligence), breach of statutory duty, or otherwise - shall not exceed the greater of:
We shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of profits, revenue, goodwill, data, or business opportunities, even if we have been advised of the possibility of such damages.
If you are a consumer, you may have statutory rights that cannot be excluded under the Consumer Rights Act 2015. Nothing in this section affects those rights.
You agree to indemnify, defend, and hold harmless Siften and its officers, employees, and agents from and against any claims, damages, losses, costs, and expenses (including reasonable legal fees) arising out of or relating to: (a) your use of the Service; (b) any Content you publish; or (c) your breach of these Terms.
The Service integrates with or links to third-party services (including Stripe for payments). We are not responsible for the content, privacy practices, or availability of those services. Your use of third-party services is governed by their own terms and policies.
These Terms and any dispute or claim arising out of or in connection with them (including non-contractual disputes or claims) shall be governed by and construed in accordance with the law of England and Wales.
Both parties agree to first attempt to resolve any dispute informally by contacting us at hello@siften.com. If the dispute is not resolved within 30 days, either party may refer the matter to the courts of England and Wales, which shall have exclusive jurisdiction, subject to any statutory rights you have as a consumer to bring proceedings in a court local to you.
We may update these Terms from time to time. When we make material changes we will update the "Last updated" date above and notify registered users by email at least 14 days before the changes take effect. Your continued use of the Service after that date constitutes acceptance of the revised Terms. If you do not agree to the changes, you must stop using the Service and may close your Account.
