1. About these terms

1.1 These terms and conditions (Terms) set out the terms on which we provide Astrenian (clause 2.2), together with everything we provide through it (Software). Information about it, including its prices, is on our website at astrenian.com (Website). You must accept these Terms for us to provide the Software to you.

1.2 Please read these Terms carefully. These Terms tell you who we are and other important information. They describe how we provide our Software, set out your rights and responsibilities and tell you what to do if there is a problem. These Terms also limit our liability.

1.3 Some of these Terms only apply if you are a consumer. This means that you are an individual using the Software wholly or mainly for purposes outside your trade, business, craft or profession. Terms that only apply to consumers, or only to those who are not consumers, are marked clearly.

1.4 By creating an account or using our Software, you are agreeing to these Terms. If you do not agree to these Terms, you must not create an account or use our Software.

1.5 We may change these Terms from time to time, for example because of changes in the law or regulatory requirements, for security or safety reasons, to prevent abuse, because of circumstances beyond our reasonable control, or as we develop the Software and its features. When we do:

  • 1.5.1 if a change is reasonably likely to affect your use of the Software or your legal rights, we will tell you by email or in the Software at least 30 days before it takes effect, unless it is needed sooner because of a change in the law or for security reasons;
  • 1.5.2 other changes, such as corrections and clarifications, take effect when we publish them here;
  • 1.5.3 changes apply only from the date they take effect; and
  • 1.5.4 if you do not agree to a change, you may cancel your subscription before it takes effect. If you continue to use the Software after that date, you accept the changed Terms, and we may ask you to confirm this when you next sign in.

Changes to prices are covered in clause 9.

1.6 These Terms cover your use of the Software. For information regarding access to and use of our Website, please see our Website Terms of Use at https://astrenian.com/terms.

You are responsible for activity under your account where you have not kept your sign-in methods secure.

6. Licence

6.1 Where you use the Software in accordance with these Terms, and while your trial or subscription is active (and afterwards only as these Terms allow, for example to export your data):

  • 6.1.1 we grant you a non-exclusive, non-transferable, non-sublicensable licence to use the Software through your account, for your own personal purposes or, if you use it for an organisation, for that organisation’s internal purposes; and

8. Intellectual property and your content

8.1 You agree that we and our licensors own all Intellectual Property Rights in the Software. These Terms do not grant you any rights to any Intellectual Property Rights in the Software except as expressly set out in these Terms.

8.2 To the extent that you acquire any Intellectual Property Rights in the Software (but not in Your Content, see clause 8.5) you will, on our written demand, assign or procure the assignment of such Intellectual Property Rights with full title guarantee (including by way of present assignment of future Intellectual Property Rights) to us. You shall execute all such documents and do such things as we may consider necessary to give effect to this clause 8.2 at your own cost.

8.3 Astrenian is a registered trade mark of ASTRENIAN LTD (UK registration UK00004198594). You must not use our trade marks or our trade names on your website or in any marketing materials without our express written consent.

8.4 For the purpose of this clause 8, Intellectual Property Rights means copyright, patents, rights in confidential information, know-how, trade secrets, trademarks, trade names, design rights, get-up, database rights, chip topography rights, mask works, utility models, domain names, rights in computer software and all similar rights of whatever nature and, in each case:

  • (a) whether registered or not;
  • (b) including any applications to protect or register such rights;
  • (c) including all renewals and extensions of such rights or applications;
  • (d) whether vested, contingent or future; and wherever existing.

8.5 As between you and us, you own all rights in the content you create, upload, store or collect in the Software, including content other people send you through it (Your Content). Your Content is not part of the Software, and clauses 8.1 and 8.2 do not apply to it. You may use and adapt content we provide for you to start from as part of Your Content.

8.6 You give us a worldwide, non-exclusive, royalty-free licence to host, store, copy, process, transmit, back up and display Your Content, to change its format and to index it, and to let our service providers do so for us, only as needed to provide, secure and support the Software for you, to comply with the law and enforce these Terms, and to make Your Content available to others where you choose to share or publish it through the Software. This licence ends when Your Content is deleted, except as set out in section 9 of our Privacy Notice.

8.7 You are responsible for Your Content. You must have all the rights and permissions needed to upload, store, share and publish it, including for any personal data about other people that it contains or that you collect through the Software.

8.8 We do not access Your Content except where needed to provide the Software or keep it secure and working, when you ask us to help you with it, to act on a report or a suspected breach of these Terms or our Acceptable Use Policy, or where the law requires it. We do not sell Your Content or use it to train artificial intelligence models.

8.9 We may remove or disable access to Your Content, for example by disabling something you have shared or published, where it breaches these Terms, our Acceptable Use Policy or the law, or where we are legally required to. We will tell you when we do, unless the law or the need to protect others prevents it.

8.10 If you send us feedback or suggestions, we may use them freely, without any obligation to you.

9. Price and payment

9.1 The price for our Software will be shown in the Software and on the Website, and as set out in your order (Price). The Price includes any sales tax, VAT or GST that applies where you live, as shown at checkout.

9.2 We may change our prices from time to time. If we change the Price of your subscription, we will tell you by email at least 30 days before, and the new Price will apply from your first payment after that date. If you do not agree, you may cancel your subscription before then. A change to our prices will not otherwise affect existing orders unless:

  • 9.2.1 the information you provided us in relation to your order was materially different from the information we required in order to provide the Software; or
  • 9.2.2 there has been an error in the Software or on the Website regarding the pricing of any of our Software and this affects your order. If this happens, we will try to contact you using the contact details you provided when you placed your order, and we will give you the option to re-confirm your order at the correct price or to cancel your order.

9.3 Your subscription starts with a free trial of 3 days, for which you add a payment method at checkout. We will remind you by email before your trial ends. Unless you cancel before it ends, your subscription will start and the Price will be charged automatically when the trial ends, and then every month until you cancel. All amounts due must be paid in full in advance.

  • 9.3.1 Each person may have one free trial.
  • 9.3.2 You can end your trial early and start your paid subscription at any time.
  • 9.3.3 Lower usage limits (clause 12.5) apply during the free trial, and are lifted when your paid subscription starts.
  • 9.3.4 If a payment fails, we or our merchant of record will try to take it again and let you know. If it still cannot be taken, your subscription will end and your account will become read-only as set out in clause 14.2.

9.4 You pay at the checkout in the Software, by card or another payment method offered there. All payments need to be authorised by your card issuer or payment provider.

9.5 Our orders are sold by Onelink, part of the Stripe group, as named at checkout, which acts as reseller and merchant of record for all orders. Onelink sells your subscription to you, takes your payment, makes any refunds, charges and accounts for any sales tax, VAT or GST, and sends your receipts and invoices. Its payment terms are shown at checkout and apply to your payment; these Terms apply to your use of the Software. Payments appear on your statement beginning with LINK.COM*. You can contact Onelink’s support or us about a payment.

9.6 You can cancel your subscription at any time in Settings, or by emailing us at info@astrenian.com from the email address on your account. Cancelling stops future payments: your subscription stays active until the end of the period you have paid for and then ends. Cancelling does not give you a refund, except as set out in clause 10 or where clause 11 or the law gives you one.

10. Your rights as a consumer

This clause 10 only applies to you if you are a consumer (see clause 1.3).

10.1 You can cancel during your free trial without paying anything (clause 9.6).

10.2 After your first payment, you have 14 days to change your mind and ask us to cancel your subscription and refund that payment in full. This applies to your first payment only, and includes your legal right to cancel.

10.3 If you later start another subscription, you have 14 days from its start to change your mind, as the law allows. Because you asked for the Software to be available straight away, we may deduct an amount for the days you used before telling us.

10.4 To change your mind, email us at info@astrenian.com from the email address on your account, or contact our merchant of record’s support (clause 9.5). We will issue your refund no later than 14 days after the day you tell us, to the payment method you used.

10.5 These rights are in addition to any rights you have under the law where you live. If you live in the UK, you can find more information about your consumer rights from Citizens Advice at www.citizensadvice.org.uk or on 0808 223 1133.

11. If the Software is faulty

This clause 11 only applies to you if you are a consumer (see clause 1.3).

11.1 We must provide the Software with reasonable care and skill and as described (clause 4.1) and, where the law treats any part of it as digital content, of satisfactory quality and fit for purpose. We are under a legal duty to supply Software in conformity with our contract with you.

11.2 If the Software is faulty or not as described, please contact us as soon as reasonably possible at info@astrenian.com and we will put it right within a reasonable time and without significant inconvenience to you. Where we are unable to do so, you may be entitled to a price reduction or a full or partial refund, as the law provides. A problem caused by your device or browser (clause 4.4) or by an event outside our reasonable control (clause 18) is not a fault in the Software.

12. Your obligations and restrictions

12.1 You agree that:

  • 12.1.1 you will comply with these Terms, and any other documents referred to in them, when using the Software and our Website; and
  • 12.1.2 in reading and accepting these Terms, you are aware of and understand your rights and responsibilities, and if you are not sure, you have contacted us at info@astrenian.com for help or more information.

12.2 If you connect an account you hold with another provider, you authorise us to access it and act on it as you ask through the Software. That provider’s own terms apply to your use of it, and you must comply with them. We are not responsible for other providers’ services, including their availability, their changes or how they handle your data. You can disconnect at any time, which stops our access.

12.3 When you use the Software to send emails or other messages to people, you must only send them to people who expect them or would reasonably want them, in line with our Acceptable Use Policy.

12.4 When you share or publish Your Content through the Software, anyone who has access to it, for example through a link, can see it, and you are responsible for what you share and who you share it with. If you use the Software to collect information from other people, you are responsible for collecting and using it lawfully. We do not promise that content people share or publish is accurate or safe, and anyone who opens it does so at their own risk. You can stop sharing or publishing at any time.

12.5 Your use of the Software is subject to usage limits, as shown in the Software. Activity beyond them may be slowed or refused. We will give you notice of any change that materially reduces your limits, as set out in clause 1.5.

13. Data protection

13.1 We shall comply with the provisions and obligations imposed on us by the Data Protection Laws at all times when processing Personal Data in connection with these Terms.

13.2 For the purpose of this clause 13, Data Protection Laws means all data protection and privacy laws that apply to us, including in the United Kingdom:

  • (a) the UK GDPR as defined in section 3(10) of the Data Protection Act 2018, and supplemented by section 205(4) (UK GDPR);
  • (b) the Data Protection Act 2018; and
  • (c) the Privacy and Electronic Communications Regulations 2003 (SI 2003 No. 2426),

in each case as amended, updated or replaced from time to time, and the term Personal Data shall have the meaning set out in the UK GDPR.

13.3 Our Privacy Notice at https://astrenian.com/privacy explains how we collect and use personal data about you.

13.4 Where Your Content includes personal data about other people, you are responsible for it as set out in clause 8.7, and we use it only to provide the Software to you as set out in these Terms.

14. Term and termination

14.1 The contract starts when your order is accepted (clause 3.3) and continues, beginning with your free trial and then month by month (clause 9.3), until:

  • 14.1.1 you cancel your subscription (clause 9.6) and the period you have paid for ends;
  • 14.1.2 you change your mind under clause 10;
  • 14.1.3 it ends under clause 11;
  • 14.1.4 a payment cannot be taken (clause 9.3.4);
  • 14.1.5 we end it under clause 15; or
  • 14.1.6 you delete your account (clause 14.3).

14.2 After your subscription ends, your account becomes read-only for 30 days: you can still sign in, view and export Your Content, but not change it, and anything the Software does in the background for you stops. We will email you before your account is deleted. You can subscribe again during these 30 days to restore full use. At the end of the 30 days, your account and Your Content are deleted as set out in clause 14.4.

14.3 You can export Your Content at any time in Settings, including while your account is read-only or suspended. You can delete your account at any time in Settings. Deletion takes effect 7 days after you ask, and you can cancel it until then. Deleting your account ends your subscription straight away; refunds apply only as set out in clause 9.6.

14.4 When your account is deleted, we erase it and Your Content within 30 days, except as set out in section 9 of our Privacy Notice.

15. Our right to suspend or end the contract

15.1 We may suspend your account, or limit or refuse your access to the Software, immediately and without notice, for as long as reasonably needed, where we reasonably believe it is needed to protect the Software, other people or us, including where:

  • 15.1.1 you breach these Terms or our Acceptable Use Policy;
  • 15.1.2 you do or take part in anything illegal when using the Software or our Website;
  • 15.1.3 your account is being used in a way that threatens the security of the Software or of other people’s accounts or data;
  • 15.1.4 you abuse free trials or try to get around our limits; or
  • 15.1.5 the law requires us to.

Suspension may happen automatically.

15.2 While your account is suspended, you cannot use the Software and anything it does in the background for you stops, but you can still export Your Content (clause 14.3). We will email you when we suspend your account and when we restore it, unless the law or security prevents it. If you think we have made a mistake, email us at info@astrenian.com and a person will review it. As soon as reasonably possible, we will either restore your account or end the contract under clause 15.3.

15.3 We may end the contract by telling you by email if you commit a serious or repeated breach of these Terms or our Acceptable Use Policy, if you do or take part in anything illegal when using the Software or our Website, or if a payment cannot be taken (clause 9.3.4). Clause 14.2 then applies.

15.4 We may also end the contract for any other reason by giving you at least 30 days’ notice by email. If you have paid for any period after the end date, we will refund that part.

15.5 You can cancel under clauses 9.6, 10 and 11. Our rights to suspend or end the contract do not affect any of your legal rights.

16. Our liability to you

16.1 We are not liable to you for any losses you incur where the delivery of the Software is delayed or cannot be delivered because you fail to make information available to us or fail to provide us with adequate instructions or information to allow us to deliver the Software.

16.2 We are not liable to you for any loss or damage that was not foreseeable, or any loss or damage not caused by our breach or negligence.

This clause 16.3 only applies to you if you are not a consumer (see clause 1.3).

16.3 We exclude all warranties, representations, conditions and all other terms of any kind whatsoever implied by statute or common law, to the fullest extent permitted by applicable law.

16.4 Nothing in these Terms excludes or limits our liability for any death or personal injury caused by our negligence, liability for fraud or fraudulent misrepresentation, or any other liability that the law does not allow us to exclude or limit.

The following clause 16.5 only applies to you if you are a consumer (see clause 1.3).

16.5 If we breach these Terms or are negligent, we are liable to you for foreseeable loss or damage that you suffer as a result. By ‘foreseeable’ we mean that, at the time the contract was made, it was either clear that such loss or damage would occur, or you and we both knew that it might reasonably occur, as a result of something we did (or failed to do). We only supply the Software for your personal use, and are not liable to you for any loss of profit, loss of business, business interruption or loss of business opportunity.

The following clauses 16.6 to 16.8 only apply to you if you are not a consumer (see clause 1.3).

16.6 We are not liable to you for any indirect or consequential loss, or for any loss of profits, revenue, business, goodwill or anticipated savings, or any loss or corruption of data.

16.7 Any claim against us must be brought within one year of the date you became aware, or should reasonably have become aware, of it.

16.8 You will compensate us for any claims, losses and costs we suffer because of a claim by someone else that arises from Your Content or from your breach of these Terms or our Acceptable Use Policy.

16.9 Our total liability to you for all claims arising from these Terms or the Software is limited to the greater of the total amount you paid for your subscription in the 12 months before the event giving rise to the claim, and £100. This does not apply to anything in clause 16.4 or, if you are a consumer, to your legal rights in clause 11.

16.10 We recommend that you keep your own copies of any of Your Content that is important to you, which you can make at any time by exporting it (clause 14.3).

17. Complaints

17.1 If you have a complaint, please email us at info@astrenian.com and we will respond as soon as reasonably possible.

18. Uncontrollable events

18.1 We shall not be in breach of these Terms nor liable for delay in performing, or failure to perform, any of our obligations under these Terms if such delay or failure result from any Uncontrollable Events.

18.2 In such circumstances we shall be entitled to a reasonable extension of the time for performing such obligations. If the period of delay or non-performance continues for 30 days, you may cancel your subscription with immediate effect, and we will refund any amount you have paid for the period you could not use.

18.3 In this clause 18, Uncontrollable Events means an event outside of our reasonable control including, without limitation: failures or outages of the internet, of telecommunications networks or of power supplies, or of the hosting, cloud, payment, email or other third-party services we rely on, or of providers whose accounts you have connected; cyber attacks, including denial-of-service attacks, that we could not reasonably prevent; acts of government or regulators, sanctions or changes in law; natural disaster, epidemic or pandemic, terrorist attack, civil war, civil commotion or riots, war or armed conflict, nuclear, chemical or sonic boom, collapse of buildings, fire, explosion or accident, any labour or trade dispute, strikes, industrial action or lockouts.

19. General

19.1 You are not allowed to transfer your rights or obligations under these Terms to anyone without our prior written consent. We may transfer our rights and obligations under these Terms to another business without your consent, but we will notify you of the transfer and make sure that your rights are not adversely affected as a result.

19.2 If any provision of these Terms (or part of any provision) is or becomes illegal, invalid or unenforceable, the legality, validity and enforceability of any other provision of these Terms will not be affected.

19.3 If you breach these Terms and we take no action, we will still be entitled to use our rights and remedies in any other situation where you breach these Terms.

19.4 Under these Terms, notices must be in writing. We will send notices to the email address on your account or show them in the Software. You must send notices to us at info@astrenian.com or to our registered address (clause 2.1). Emails will be deemed delivered the same day (or the next business day, if sent on a non-business day or after 5pm on any business day at the recipient’s location). Notices shown in the Software will be deemed delivered when first shown to you. Letters will be treated as delivered when they are received. While you have an account, we will send you emails about your account, your subscription, security and these Terms, which you cannot switch off. You can choose which other notifications you receive in Settings.

19.5 These Terms, our Acceptable Use Policy and the terms of each accepted order are the entire agreement between us, together with the payment terms of our merchant of record (clause 9.5), and replace any terms and conditions of purchase or supply that you have been provided with previously. If you are a consumer, this does not affect information we gave you before you ordered that the law makes part of our contract (clause 4.1).

19.6 These Terms and any dispute or claim arising out of them are governed by the laws of England and Wales. If you are not a consumer, the courts of England and Wales have exclusive jurisdiction. If you are a consumer, you may bring a claim in the courts of England and Wales or in the courts of the country or part of the United Kingdom where you live, and you keep the protection of any mandatory laws of the country where you live.

19.7 A person who is not a party to these Terms has no right to enforce any of them.

19.8 Any clause of these Terms that by its nature should continue after the contract ends will continue, including clauses 8, 14.2 to 14.4, 16 and 19.
