Terms of Service

Version 2026-09-01 · Effective 1 September 2026 · Issued by Sequonyx Inc., Ontario, Canada
Companion document: Privacy Policy (same version). A signed Pilot Letter, where one exists, forms part of this agreement.

1. Who we are and how you agree

1.1 Tacillon is a service operated by Sequonyx Inc., a corporation incorporated in Canada with its principal place of business in Ontario ("Sequonyx", "we", "us"). Tacillon lets an organisation capture a work procedure once, as steps with video, and have its people run that procedure later, step by step, with a record of what was confirmed and when.

1.2 These Terms of Service (the "Terms") are an agreement between Sequonyx and the organisation that holds the account (the "Enterprise", "you"). The Service is offered to organisations, not to individuals acting as consumers.

1.3 How you agree. You agree to these Terms by ticking the agreement box when you create an Enterprise account, or by ticking the agreement box on the acceptance screen the app shows after you sign in. The person who ticks the box confirms that they have authority to bind the Enterprise. If you do not agree, do not tick the box; the app will not let you go further, and you may sign out.

1.4 We record your agreement: the version of these Terms, the date and time, the email address of the account that agreed, the control used to agree, and a digital fingerprint (SHA-256) of the exact text shown to you. You may ask us for a copy of that record at any time.

1.5 If you and we have also signed a Pilot Letter, it forms part of this agreement. Where the Pilot Letter and these Terms disagree, the Pilot Letter wins for that Enterprise.

2. Definitions

3. Pilot status of the Service

3.1 The Service is currently offered as a pilot. It works, and its safety-critical behaviour is tested before every release, but it is early software used by a small number of organisations.

3.2 During the pilot we may add, change or remove features. We will tell you in advance about a change that removes something you rely on, and we will never remove your ability to export your Customer Content.

3.3 There is no service-level commitment during the pilot. We aim for the Service to be available whenever you need it, and its design lets a signed-in phone keep working without a connection, but we do not promise uptime.

4. Your account, your people, your responsibilities

4.1 Credentials. One Enterprise account is one login. Keep the password and any device signed into the account secure. You are responsible for everything done under your account, and you will tell us promptly at the contact in section 20 if you believe it has been used without authority.

4.2 Your people. Profiles inside the Service are display names, not separate logins. You decide who may use a signed-in device. You are responsible for the conduct of your Authorized Users and for making sure each of them knows what the Service records (section 8.4).

4.3 Your procedures are yours. The steps, warnings, videos and safety assertions in a guide are written by your own people about your own equipment and workplace. We do not review them for accuracy, completeness or safety, and we have no way to know whether a procedure is correct for your site. You are responsible for the content of every guide and for keeping it current.

4.4 Tacillon is a tool, not a safety authority. The Service helps you document and follow procedures and creates a record of what was confirmed. It does not replace worker training, competent supervision, hazard assessment, lockout procedures, or any duty you have under the Occupational Health and Safety Act (Ontario), its regulations, or any other law. A step confirmed in the Service is a record that a person said they did something; it is not proof that the thing was done safely or done at all.

4.5 What not to put in. Do not put into the Service any health information about a person, any government identifier, any financial account information, or any Personal Information beyond what the Service asks for (a display name for the person working, and an email address for a product-guide registration). If you record a video, make sure the people in it know they are being recorded and why (section 8.4).

4.6 Lawful use. You will use the Service in compliance with all laws that apply to you, including privacy and employment law, and you will have every right and consent needed for the Customer Content you submit.

5. Your content and our limited licence

5.1 You own your Customer Content. As between you and us, you keep every right, title and interest, including all intellectual property rights, in your Customer Content. Nothing in these Terms transfers ownership of it to us.

5.2 The only licence we take. You grant Sequonyx and its hosting providers a non-exclusive, worldwide, royalty-free licence to host, store, copy, transmit, display, back up and process your Customer Content solely as necessary to provide, secure, support and maintain the Service for you and to comply with law. This licence ends when your Customer Content is deleted under section 13, except for the retention we describe there.

5.3 What we will not do with your Customer Content. We will not:

1. sell it, rent it, or share it with anyone except the hosting providers named in the Privacy Policy, who act only on our instructions;
2. use it for advertising, or to build profiles of your workers;
3. use it, or any Personal Information in it, to train, fine-tune or evaluate any artificial-intelligence or machine-learning model, whether ours or a third party's, including any robotics or automation model. The only data we may use for that purpose is Performance Data (section 6), which is built without any Customer Content in it, and any data you may later choose to contribute under a separate Research Data Program agreement (section 7);
4. look at the contents of your guides, videos or records except when you ask us for support, when we need to investigate a security incident or a suspected breach of these Terms, or when the law requires it. We will tell you when we have done so, unless the law forbids it.

5.4 Our property. The Service, its software, design, Documentation and the Performance Data are owned by Sequonyx and its licensors. You receive a right to use the Service under these Terms and nothing more. Suggestions you give us about the Service may be used by us without obligation, provided we never attribute them to you or disclose your Customer Content in doing so.

6. Performance Data

6.1 What it is. Performance Data is data about how the Service is used that has been aggregated (combined across many uses and, wherever practicable, across several Enterprises) and anonymized (irreversibly altered so that there is no serious possibility that it could identify you, any Authorized User, any other person, or any specific site or piece of equipment, alone or combined with other information). Performance Data is derived from the structure of use. Examples: how many steps a typical procedure of a given type has; how long a step of a given severity takes to confirm; how often a gate is failed and re-attempted; which abort reasons are common; how often a QR scan disagrees with a label; which categories of equipment appear together in a procedure.

6.2 What it never contains. Performance Data does not contain, and is never derived from: video; audio; photographs or other images; the text of any step, warning, safety assertion or phraseology; equipment names, tag values, serial numbers or manual links; profile names, email addresses or any other identifier of a person; the name of your Enterprise or any site; free text of any kind; or any value from which any of these could be recovered. Where a category is needed (for example, "pump" or "generator"), it is drawn from a fixed list we maintain, not from your text.

6.3 How we make it. We apply the standard set by the Office of the Privacy Commissioner of Canada for information "made anonymous": before any dataset is treated as Performance Data we assess re-identification risk, including the size of the population it was drawn from, and we apply aggregation thresholds, suppression of rare values and, where needed, statistical perturbation so that no record can be traced to an Enterprise or a person. We reassess this as techniques change. We keep a written description of the method and will share it with you on request.

6.4 What we may do with it. Performance Data belongs to Sequonyx. We may use it, during and after the term of this agreement, to operate, secure, understand and improve the Service; to develop new products and features; to conduct and publish research; and to develop, train and evaluate models for automation, including robotics. We may share Performance Data with research partners and collaborators under written agreements that prohibit any attempt at re-identification.

6.5 Our promise. We will never attempt to re-identify any Enterprise or person from Performance Data, and we will require the same of anyone we share it with. If we ever find that a dataset we treated as Performance Data could in fact identify an Enterprise or a person, we will stop using it, correct it, and tell any affected Enterprise.

6.6 Why this is in the Terms. Anonymized information is not Personal Information under Canadian privacy law and is not Customer Content under this agreement, so we ask for your agreement to this section as a matter of contract, in plain sight, rather than relying on that legal position alone. A Pilot Letter may vary this section for your Enterprise.

7. Research Data Program (not granted by these terms)

7.1 We expect that recorded procedures could one day help teach machines to perform physical work. These Terms do not grant us any right to use Customer Content for that purpose.

7.2 If we ever propose to use any Customer Content, including video or audio, for research or model training, we will do so only under a separate written Research Data Program agreement that you may accept or decline without any effect on your use of the Service; that describes exactly which content is included, how faces, voices and other Personal Information are removed or protected, and how the results may be used; and that is supported by the express, informed consent of each person who appears in the content, obtained in a manner we agree with you in advance. Nothing in the Service will be conditioned on joining such a program.

8. Personal information and privacy

8.1 Our Privacy Policy describes what Personal Information the Service handles, why, where it is stored, who our hosting providers are, how long we keep it and how individuals can exercise their rights. It forms part of these Terms.

8.2 Roles. Your Enterprise decides what the Service is used for and who uses it, and is responsible to its own workers and customers for that decision. Sequonyx processes Personal Information inside Customer Content on your behalf and on your instructions, and is independently responsible for safeguarding it while it is in our systems. Each of us complies with the privacy law that applies to us.

8.3 Where your data is stored. Customer Content is stored by our hosting providers in data centres in the United States, and is therefore subject to United States law while it is there. We choose providers that offer contractual and technical safeguards comparable to those required in Canada, and we list them in the Privacy Policy. If this is a concern for your Enterprise, raise it with us before the pilot begins; a Pilot Letter may set out an alternative.

8.4 Telling your people. Before an Authorized User first works under a profile or appears in a video, you will tell them, in plain terms, that the Service records their display name, the steps they confirm, the times and the method of confirmation, and any video or audio captured; that these records are stored outside Canada; and how they can ask you about them. We provide a short notice for this purpose in the Documentation, and the acceptance box at sign-up confirms you have done or will do this.

8.5 Requests from individuals. If one of your workers asks to see, correct or delete Personal Information about them, that request is yours to answer, and we will help you within ten business days. If someone contacts us directly, we will tell them to contact you unless the law requires otherwise.

8.6 Security incidents. If we become aware of unauthorised access to your Customer Content, we will tell you without undue delay and in any case within 72 hours of confirming it, with what we know and what we are doing. You are responsible for any notification your Enterprise must make to individuals or regulators, and we will give you the information you need to make it.

9. The audit record

9.1 The Service keeps a sequence-locked record of what was confirmed during a procedure: each entry carries a digital fingerprint of the entry before it, so any later alteration is detectable. A copy is kept on the device and a copy is archived on our servers as connectivity allows.

9.2 The archive is append-only. We cannot edit or delete individual entries for you, and we will not do so for anyone else, because the value of the record depends on that. You may export the record at any time. Deleting your Enterprise (section 13) deletes its archive.

9.3 What the record is and is not. The audit record is evidence generated automatically as work happened. It is risk and liability mitigation, not a court-proof electronic signature. We make no representation about how any court, regulator, insurer or tribunal will treat it.

10. Public product guides and registrations

10.1 If you publish a Product User Guide, anyone with its link or QR code can open it without logging in. You decide what to publish and when to unpublish it.

10.2 A published guide may ask a reader to record a warranty activation or a safety acknowledgement, which collects the reader's email address and, for a worker, their employer's name, along with the exact text they agreed to. These registrations are your Customer Content. You are responsible for having a lawful basis to contact the people who register and for honouring any request they make about their information. We store the registrations for you and do not use them for any purpose of our own.

11. Acceptable use

You will not, and will not allow anyone to: (a) use the Service to break the law or infringe anyone's rights; (b) upload malicious code or attempt to gain access to another Enterprise's data or to our systems beyond what the Service presents to you; (c) copy, modify, reverse-engineer or resell the Service; (d) use the Service to build a competing product; (e) run security testing against the Service without our written agreement; (f) remove or obscure any notice in the Service; or (g) overload the Service deliberately. We may suspend an account that does any of these, after notice where practicable.

12. Fees

12.1 During the pilot the Service is provided free of charge unless a Pilot Letter says otherwise.

12.2 If we introduce fees, we will give you at least 30 days' written notice, and you may end this agreement before the fees begin without penalty. Any fees are exclusive of applicable taxes.

13. Term, suspension, ending the agreement, and your data afterwards

13.1 These Terms apply from the moment you agree to them and continue until ended by either of us.

13.2 You may end the agreement at any time by telling us at the contact in section 20 and ceasing to use the Service.

13.3 We may suspend your access, with notice where practicable, if we reasonably believe your account is being used in breach of section 11, poses a security risk, or is the subject of a legal demand. We may end the agreement on 30 days' written notice for any reason, or immediately if you materially breach these Terms and do not cure the breach within 14 days of our notice, or if we end the pilot for all Enterprises.

13.4 Your data afterwards. For 60 days after the agreement ends you may ask us for an export of your Customer Content, including the audit archive, in a common machine-readable format (JSON), and we will provide it within 30 days of your request at no charge. After that 60-day period we will delete your Customer Content from our active systems within 30 days, and from backups as they rotate (currently within a further 30 days), unless the law requires us to keep it longer.

13.5 Sections 5.1, 5.3, 5.4, 6, 7, 9.3, 13.4, 14, 15, 16, 18 and 19 survive the end of this agreement.

14. What we promise and what we do not

14.1 We promise to provide the Service with reasonable skill and care, to safeguard your Customer Content as described in the Privacy Policy, and to honour sections 5, 6 and 7.

14.2 Otherwise the Service is provided "as is" during the pilot. To the fullest extent the law allows, we disclaim all other warranties and conditions, express or implied, including fitness for a particular purpose and uninterrupted or error-free operation. In particular, we do not warrant that any procedure in the Service is correct, complete or safe, because we did not write it and cannot assess it.

15. Limits on liability

15.1 To the fullest extent the law allows, neither of us is liable to the other for indirect, consequential, special or punitive damages, or for loss of profit, revenue, business or data, however arising.

15.2 To the fullest extent the law allows, Sequonyx's total liability to you for all claims arising out of or related to this agreement is limited to the greater of the fees you paid us in the 12 months before the event giving rise to the claim and CAD $100.

15.3 These limits do not apply to liability that cannot be limited by law, to either party's breach of section 8 or the Privacy Policy, to Sequonyx's breach of sections 5.3 or 6.5, or to your breach of section 11 or your indemnity in section 16.

15.4 You acknowledge that the Service is free during the pilot and that these limits reflect that.

16. Your indemnity

You will defend and indemnify Sequonyx against third-party claims, and the reasonable costs of them, to the extent they arise from your Customer Content, from your use of the Service in breach of these Terms or of law, or from any injury, loss or damage connected with a procedure documented or followed using the Service, except to the extent caused by our breach of this agreement or our negligence.

17. Changes to these terms

17.1 When we change these Terms or the Privacy Policy we publish a new version with a new date. The app will ask you to read and agree to the new version before you can continue past sign-in. No change binds you until you have agreed to it in this way, and you may decline and export your data instead.

17.2 We will not change section 5.3, 6 or 7 in a way that gives us more rights over your Customer Content without also telling you in writing at least 30 days before the new version takes effect.

18. Governing law and disputes

18.1 This agreement is governed by the laws of the Province of Ontario and the federal laws of Canada that apply there, without regard to conflict-of-laws rules. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

18.2 If a dispute arises, each of us will first raise it in writing with the other and a senior person from each side will try in good faith to resolve it within 30 days.

18.3 If that fails, the courts of Ontario have exclusive jurisdiction, and each of us submits to them. Nothing in this agreement requires arbitration, prevents you from bringing a claim together with others, or stops either of us from seeking an injunction to protect confidential information or intellectual property in any court that can grant one.

19. General

19.1 Entire agreement. These Terms, the Privacy Policy and any Pilot Letter are the whole agreement between us about the Service and replace any earlier discussions. Order of precedence: Pilot Letter, then these Terms, then the Privacy Policy.

19.2 Notices to us go to the contact in section 20; notices to you go to the email address on the Enterprise account. Either of us may change our address by notice.

19.3 Assignment. You may not assign this agreement without our written consent, not to be unreasonably withheld. We may assign it to a successor to our business that assumes our obligations, and we will tell you if we do.

19.4 Severability and waiver. If any part of these Terms is unenforceable, the rest stays in force and the unenforceable part is limited to the minimum extent necessary. A failure to enforce a right is not a waiver of it.

19.5 Force majeure. Neither of us is liable for delay or failure caused by events beyond our reasonable control, other than payment obligations.

19.6 Language. These Terms are written in English. The parties have expressly requested that this agreement and all related documents be drawn up in English. Les parties ont expressément demandé que la présente convention et tous les documents connexes soient rédigés en anglais.

19.7 Independent parties. Nothing here creates a partnership, joint venture, agency or employment relationship between us.
