Rulecore AB is referred to below as "we", "us", or "Rulecore".
2. Definitions
- "Software" — the Arrows & Boxes application, in any form we make available, including the web application at arrowsboxes.com, its documentation, and any updates we provide.
- "You" — the natural or legal person entering into this Agreement. If you use the Software on behalf of an organisation, "you" means that organisation, and you confirm you are authorised to bind it.
- "Your Content" — the diagrams, text, notes, scripts, files, and any other material you create, import, or process using the Software.
- "Consumer" — a natural person acting for purposes outside their trade, business, craft, or profession.
- "Open-Source Components" — the third-party open-source software bundled with the Software, as listed in the accompanying third-party notices (see clause 6).
3. Acceptance and scope
3.1 You accept this Agreement by clicking "I agree" (or an equivalent control) when the Software first asks you to, or — if you gain access to the Software in a way that does not present that control — by installing, accessing, or using the Software.
3.2 If you do not accept this Agreement, do not use the Software.
3.3 This Agreement governs the Software only. Our processing of personal data in connection with the website that delivers the Software is described in our Privacy Policy, which forms part of this Agreement by reference.
3.4 Open-Source Components are not licensed to you under this Agreement; they are licensed under their own terms (clause 6).
4. License grant
4.1 Subject to your compliance with this Agreement, we grant you a worldwide, royalty-free, non-exclusive, non-transferable, non-sublicensable license to use the Software for your own personal or internal business purposes, for as long as this Agreement remains in force.
4.2 The Software is provided free of charge. No fee is payable, and none of your personal data is required as consideration for it.
4.3 This license is granted to you and, where you are an organisation, to your personnel acting on your behalf. It conveys no right to provide the Software to anyone else.
5. Restrictions
5.1 Except as clause 5.2 permits, you may not:
- (a) redistribute, resell, rent, lease, lend, or sublicense the Software, or make it available to third parties as a service;
- (b) reverse-engineer, decompile, or disassemble the Software, or derive its source code;
- (c) modify, adapt, or create derivative works of the Software;
- (d) remove, obscure, or alter any proprietary notice, attribution, or license text in or accompanying the Software, including the third-party notices; or
- (e) use the Software to develop a product that competes with it.
5.2 These restrictions do not apply where, and to the extent that, mandatory law overrides them. In particular, nothing in clause 5.1 restricts:
- (a) your rights under Sections 26 g–26 h of the Swedish Copyright Act (lag (1960:729) om upphovsrätt till litterära och konstnärliga verk) — including the making of a back-up copy, observing, studying, or testing the Software to determine its underlying ideas, and decompilation for the purpose of interoperability. These rights cannot be waived by agreement, and clause 5.1(b) is subject to them;
- (b) any equivalent mandatory right you hold under the law applicable to you; or
- (c) your rights in respect of the Open-Source Components, which are governed by clause 6 and by the applicable open-source licenses. Where an open-source license permits an act that clause 5.1 prohibits, the open-source license prevails for that component.
6. Open-source components
6.1 The Software bundles Open-Source Components. Each is used under its own license, and copyright remains with its respective authors.
6.2 The complete list, with the applicable license text for each component, is provided with the
Software as THIRD-PARTY-NOTICES.txt and is reachable from the Software's About and Settings screens.
6.3 Your rights in respect of each Open-Source Component are governed exclusively by that component's license, not by this Agreement. To the extent an open-source license conflicts with this Agreement in respect of that component, the open-source license prevails.
7. Your content and your data
7.1 You own Your Content. We claim no ownership of, and no license to, Your Content. Nothing in this Agreement transfers any right in Your Content to us.
7.2 The Software stores Your Content locally. Your Content is stored in your browser's storage on your device and in files you save yourself. The Software does not transmit Your Content to Rulecore, and we have no access to it.
7.3 You are responsible for your backups. Browser storage is not a durable archive: it can be erased by clearing site data, by browser or device settings, by private/incognito modes, by storage pressure, or by faults outside our control. Use the Software's save/export feature to keep your own copies. See also clause 13.
7.4 You are responsible for Your Content, including for holding the rights necessary to use it and for complying with the law that applies to it.
8. Scripting and material you fetch
8.1 The Software includes a scripting feature that executes code you write or supply inside your browser. Scripts run with the capabilities of the page, including the ability to make network requests to addresses you specify.
8.2 Scripts are Your Content and run at your own risk. You are solely responsible for the scripts you run, for the addresses you direct them to, and for the consequences. Do not run a script you do not understand or do not trust.
8.3 The Software may allow you to retrieve material from third-party sources. We do not control, endorse, review, or accept responsibility for such material or for the sources it comes from, and retrieving it is between you and that source, on its terms.
9. Acceptable use
You may not use the Software:
- (a) in breach of applicable law, or to infringe anyone's rights;
- (b) to develop, host, or distribute malicious code, or to gain unauthorised access to any system or data;
- (c) in a way that damages, disables, or impairs the Software, the website that delivers it, or any third-party system; or
- (d) in breach of applicable export-control or sanctions law, including where you are located in, or are a national of, a country subject to a comprehensive embargo, or you appear on a restricted-party list.
10. Ownership
10.1 The Software is licensed, not sold. We and our licensors retain all right, title, and interest in and to the Software, including all intellectual-property rights.
10.2 You receive only the rights this Agreement expressly grants. No other right is granted, by implication, estoppel, or otherwise.
10.3 "Arrows & Boxes" is a trademark of Rulecore AB. Our trademarks, logos, and product names are our property, and this Agreement grants you no right or licence to use them — including in any product name, domain name, or branding of your own, and in any way that suggests endorsement by or affiliation with us.
10.4 Nothing in clause 10.3 prevents you from referring to the Software by name in ordinary descriptive or comparative use — for example, saying that a diagram was made with Arrows & Boxes.
11. Availability and updates
11.1 The Software is provided as a free service. We do not guarantee that it will be available, uninterrupted, or error-free, and we may modify, suspend, or discontinue it, in whole or in part, at any time.
11.2 We may make updates available. Updates are governed by this Agreement unless we state otherwise, and may change or remove features.
11.3 Where we discontinue the Software altogether, we will make reasonable efforts to give notice in the Software or on our website, so that you may export Your Content. Clause 7.3 continues to apply.
12. No warranty
12.1 The Software is provided "AS IS" and "AS AVAILABLE", without warranty of any kind. To the fullest extent permitted by applicable law, we disclaim all warranties, conditions, and representations, whether express, implied, or statutory, including any implied warranty of merchantability, satisfactory quality, fitness for a particular purpose, accuracy, or non-infringement.
12.2 We do not warrant that the Software will meet your requirements, that its operation will be uninterrupted or error-free, or that defects will be corrected.
12.3 Consumers: nothing in this clause 12 limits or excludes any statutory right you have as a Consumer that cannot be limited or excluded by agreement. Those rights apply in addition to, and prevail over, this clause.
13. Limitation of liability
13.1 Nothing in this Agreement limits or excludes our liability for:
- (a) death or personal injury caused by our negligence;
- (b) fraud or fraudulent misrepresentation;
- (c) our intentional misconduct or gross negligence;
- (d) liability under the Swedish Product Liability Act (produktansvarslagen (1992:18)); or
- (e) any other liability that cannot be limited or excluded under applicable mandatory law, including mandatory consumer law.
13.2 Subject always to clause 13.1, and to the fullest extent permitted by applicable law:
- (a) we are not liable for any indirect or consequential loss, nor for loss of profit, revenue, business, goodwill, anticipated savings, or opportunity, however arising;
- (b) we are not liable for any loss of or damage to data, including Your Content held in browser storage — which, as clause 7.3 explains, is not a durable archive and can be erased for reasons outside our control; and
- (c) our total aggregate liability arising out of or in connection with this Agreement or the Software is excluded in full. The Software is supplied free of charge, you pay no fee and provide no personal data as consideration for it, and this allocation of risk reflects that. Clause 13.1 is unaffected.
13.3 The exclusions and limitations in this clause 13 apply regardless of the basis of the claim, whether in contract, tort (including negligence), statutory duty, or otherwise.
13.4 Consumers: if the exclusion in clause 13.2(c) is held unenforceable in whole or in part against you as a Consumer under the mandatory law applicable to you, our liability is instead limited to the extent that law permits, and the remainder of this clause 13 continues to apply. Clause 20 (Severability) also applies.
13.5 Clause 13.2(c) does not apply to a Consumer to the extent mandatory law applicable to that Consumer does not permit a total exclusion of liability.
14. Term and termination
14.1 This Agreement takes effect when you accept it (clause 3.1) and continues until terminated.
14.2 You may terminate at any time by ceasing to use the Software.
14.3 We may terminate this Agreement or suspend your license:
- (a) with immediate effect, if you materially breach this Agreement and — where the breach can be remedied — you fail to remedy it within 30 days of our notice; or
- (b) for any other reason, on 30 days' notice given in the Software or on our website, or by e-mail if we hold your address.
14.4 On termination, the license in clause 4 ends and you must stop using the Software. Termination does not affect Your Content: it remains yours, on your device, and you may continue to use files you have exported.
14.5 Survival. Clauses 1, 2, 6, 7.1, 7.4, 10, 12, 13, 14.4, 14.5, and 16–22 survive termination.
15. Changes to this Agreement
15.1 We may change this Agreement, for example to reflect changes to the Software or to the law.
15.2 We will not change it silently. Where we make a change, we will update the version and date at the top and give you notice in the Software before the change takes effect, together with a way to read the new terms.
15.3 A change takes effect 30 days after notice, or immediately where it is required by law or is purely clerical and does not affect your rights.
15.4 If you do not accept a change, you may terminate under clause 14.2, at any time and at no cost. Your continued use of the Software after the change takes effect indicates your acceptance of it.
15.5 Previous versions of this Agreement are available from us on request at info@rulecore.com.
16. Governing law
16.1 This Agreement is governed by the laws of Sweden, excluding its conflict-of-law rules and the United Nations Convention on Contracts for the International Sale of Goods.
16.2 Consumers: this choice of law does not deprive you of the protection of the mandatory provisions of the law of the country in which you have your habitual residence (Article 6 of Regulation (EC) No 593/2008, "Rome I").
17. Disputes and jurisdiction
17.1 We would rather resolve any dispute directly. Please contact us at info@rulecore.com first.
17.2 Subject to clause 17.3, any dispute arising out of or in connection with this Agreement shall be subject to the exclusive jurisdiction of the courts of Sweden, with the Gothenburg District Court (Göteborgs tingsrätt) as the court of first instance.
17.3 Consumers: clause 17.2 does not apply to you. Under Articles 17–19 of Regulation (EU) No 1215/2012 ("Brussels Ia"), you may bring proceedings in the courts of your own domicile or in the courts of Sweden, and we may bring proceedings against you only in the courts of your domicile.
17.4 Consumers in Sweden: you may also refer a dispute to the Swedish National Board for Consumer Disputes (Allmänna reklamationsnämnden, ARN), Box 174, 101 23 Stockholm, https://www.arn.se. We will participate in ARN proceedings that ARN accepts for review.
18. Notices
18.1 Notices to us: info@rulecore.com, or Rulecore AB, Bergåsvägen 1, 433 51 Öjersjö, Sweden.
18.2 Notices to you: we may give notice in the Software, on our website, or — where we hold your address — by e-mail. A notice given in the Software is effective when first displayed to you.
19. Assignment
19.1 You may not assign or transfer this Agreement, or any right under it, without our prior written consent.
19.2 We may assign or transfer this Agreement to an affiliate, or in connection with a merger, acquisition, or sale of the assets to which it relates. We will give notice under clause 18.2 if we do. Where you are a Consumer, an assignment will not reduce your rights, and you may terminate under clause 14.2.
20. Severability
If any provision of this Agreement is held invalid, illegal, or unenforceable, that provision shall be modified to the minimum extent necessary to make it enforceable while preserving its intent as closely as possible or, if it cannot be so modified, severed. The remaining provisions continue in full force.
21. No waiver
Our failure or delay in enforcing any provision of this Agreement is not a waiver of it, and no single or partial exercise of a right prevents any further exercise of it.
22. Entire agreement
22.1 This Agreement, together with the Privacy Policy and the third-party notices, is the entire agreement between you and us in respect of the Software, and supersedes any prior statement, representation, or understanding about it — including product descriptions, documentation, and marketing material.
22.2 Clause 22.1 does not exclude liability for fraud or fraudulent misrepresentation, and does not limit any right you have as a Consumer in respect of a statement made to you.
23. Language
This Agreement is written in English, which is the governing language. Any translation is provided for convenience only. Where you are a Consumer and mandatory law entitles you to these terms in another language, that entitlement is unaffected.
