These Terms of Service (the "Terms") are a binding agreement between Symbionix SL, a company incorporated under the laws of Spain (Sociedad Limitada), holding tax identification number (CIF) B-22937023 and with registered office at Carrer de Pere IV 182, 08005 Barcelona, Spain ("AirStrings", "we", "us", "our"), and the business or organization that registers for or uses the Service ("Customer", "you", "your").
By clicking "I agree" (or an equivalent control), creating an account, or otherwise accessing or using the Service, you accept these Terms and confirm that the individual accepting them has authority to bind the Customer. If you do not agree, do not use the Service.
These Terms incorporate by reference, and you also agree to:
- the Privacy Policy;
- the Acceptable Use Policy ("AUP");
- the Data Processing Agreement ("DPA"), which governs our processing of personal data on your behalf; and
- the Subprocessor list.
Together these documents form the "Agreement". If there is a conflict, the order of precedence is: the DPA (for personal-data processing matters), then these Terms, then the other referenced documents, unless a document expressly states otherwise.
1. Definitions
1.1 "Service" means the AirStrings remote string-management platform, including the web dashboard, API, content-delivery of signed bundles via our CDN, our software development kits ("SDKs"), and related documentation and websites (including airstrings.com).
1.2 "Customer Content" means the strings, keys, locale data, translations, project metadata, and other material that you or your Users upload to, or generate within, the Service.
1.3 "User" means an individual you authorize to access the Service under your account (for example, a member of your organization or team).
1.4 "Bundle" means a packaged, cryptographically signed set of Customer Content produced by the Service for delivery to your applications via SDKs.
1.5 "Plan" means the subscription tier you select (currently Free, Pro, or Team), with the features, usage allowances, and fees described at the point of sale or on our pricing page.
1.6 "Documentation" means our then-current technical and usage documentation for the Service.
2. The Service and licence to use it
2.1 Access. Subject to the Agreement and payment of applicable fees, we grant you a non-exclusive, non-transferable, non-sublicensable right to access and use the Service and the SDKs during the term for your internal business purposes.
2.2 SDKs. The SDKs are licensed, not sold. You may integrate the SDKs into your own applications solely to consume the Service. Any open-source components of the SDKs are governed by their own licences, which control in case of conflict for those components.
2.3 Changes to the Service. We continuously improve the Service and may add, modify, or remove features. We will not materially degrade the core functionality of a paid Plan during a paid term without notice. Beta or experimental features are provided "as is" and may be changed or withdrawn at any time.
2.4 Signed bundles. All Bundles delivered by the Service are cryptographically signed (Ed25519). Signing is a core security feature of the Service; however, it is provided as a feature and not as a warranty of uninterrupted or error-free availability of delivery. Nothing in this clause limits our obligation to deliver only signed Bundles.
3. Accounts and eligibility
3.1 Business use only. The Service is offered to businesses and organizations for professional use. It is not directed to consumers. By registering, you represent that you are acting for purposes relating to your trade, business, craft, or profession.
3.2 Capacity. You must be at least 18 years old and have the legal capacity to enter into contracts. Individual Users must be at least 16 years old.
3.3 Account security. You are responsible for maintaining the confidentiality of your credentials and API keys, and for all activity under your account. Notify us promptly at support@airstrings.com if you suspect unauthorized access. API keys are secrets; treat them accordingly.
3.4 Accuracy. You agree to provide accurate account and billing information and to keep it current.
4. Plans, fees, billing, and taxes
4.1 Fees. Paid Plans are billed in euro (EUR) at the rates shown at the time of purchase. Payment is processed by our payment provider, Stripe. You authorize us and Stripe to charge your selected payment method for all fees due.
4.2 Auto-renewal. Paid subscriptions renew automatically for successive periods equal to the then-current term unless you cancel before the end of the current period. You can cancel at any time from the dashboard; cancellation takes effect at the end of the current paid period.
4.3 Non-refundable. Except where required by mandatory law, all fees are non-refundable and non-cancelable for the period in which they are charged, and there are no refunds or credits for partial periods, unused allowances, or downgrades. If we terminate your paid subscription without cause before the end of a paid period, we will refund the pro-rated portion of prepaid fees for the unused remainder of that period.
4.4 Plan changes. You may upgrade or downgrade your Plan from the dashboard. Upgrades take effect immediately and may be charged on a pro-rated basis; downgrades take effect at the start of the next billing period. Downgrading may reduce your usage allowances and features, and you are responsible for bringing your usage within the new limits.
4.5 Price changes. We may change fees. We will give you at least 30 days' prior notice (by email or in-product) before a price change takes effect for you. Price changes apply from your next renewal after the notice period. If you do not accept a price change, you may cancel before it takes effect.
4.6 Taxes. Fees are exclusive of taxes. You are responsible for all applicable taxes (including Spanish or EU VAT/IVA as applicable), except taxes on our net income. Where required, we (or Stripe on our behalf) will apply and collect VAT/IVA; you must provide a valid VAT identification number where applicable.
4.7 Non-payment. If a charge fails, we may retry it and pursue collection through Stripe's dunning process. If payment remains outstanding after a grace period of 14 days, we may suspend the Service until payment is made, and may terminate for non-payment thereafter in accordance with Section 12.
5. Customer Content and intellectual property
5.1 You own your content. As between the parties, you retain all right, title, and interest in and to Customer Content. We claim no ownership of it.
5.2 Licence to us. You grant us a worldwide, non-exclusive, royalty-free licence to host, store, process, transmit, sign, cache, back up, and deliver Customer Content, and to create Bundles from it, solely as necessary to provide, secure, and support the Service for you. We do not use Customer Content to train machine-learning or AI models, and we do not sell Customer Content.
5.3 Private vs. public projects. The licence in Section 5.2 is limited to operating the Service for private projects. If you designate a project as public (for example, an open-source localization project), you additionally grant the licence necessary to make that project's Customer Content publicly available through the Service consistent with your chosen designation. You are responsible for the consequences of making a project public.
5.4 Your responsibilities for Customer Content. You represent and warrant that you have all rights necessary to upload and use Customer Content through the Service, and that Customer Content and its use do not infringe third-party rights or violate the AUP or applicable law. You are responsible for the accuracy, quality, and legality of Customer Content.
5.5 No personal data in content, by default. The Service is designed for application strings and localization data, not for personal data. You agree not to upload personal data as Customer Content unless strictly necessary, and where you do, our processing is governed by the DPA and you act as controller (or as processor on behalf of your own controller). You warrant that you have a lawful basis for any personal data you include.
5.6 Our intellectual property. We and our licensors own all right, title, and interest in and to the Service, the SDKs (excluding their open-source components), the platform, our signing keys and infrastructure, and all related intellectual property. Except for the rights expressly granted, no rights are granted to you. You may not (and may not permit others to) copy, modify, reverse engineer, decompile, resell, sublicense, or create derivative works of the Service, use it to build a competing product, or benchmark it, except to the extent this restriction is prohibited by mandatory law.
5.7 Feedback. If you give us feedback, suggestions, or ideas about the Service, you grant us a non-exclusive, worldwide, perpetual, irrevocable, royalty-free licence to use them without restriction or obligation to you.
5.8 Our use of marks. Neither party may use the other's name or logo without prior written consent, except that we may identify you as a customer in a factual customer list unless you tell us not to at support@airstrings.com.
6. Acceptable use
6.1 Your use of the Service must comply with the Acceptable Use Policy, which is incorporated into these Terms. A violation of the AUP is a material breach of these Terms.
6.2 We may suspend or limit access as described in Section 11 and in the AUP where necessary to protect the Service, other customers, third parties, or us.
7. Third-party services and subprocessors
7.1 The Service relies on third-party infrastructure and subprocessors listed in the Subprocessor list. Their processing of personal data on our behalf is governed by the DPA.
7.2 Your use of any third-party product or integration you connect to the Service is at your own risk and subject to that third party's terms. We are not responsible for third-party products we do not control.
8. Privacy and data protection
8.1 Our handling of personal data is described in the Privacy Policy. Where we process personal data on your behalf as a processor, the DPA applies and is incorporated into these Terms. By accepting these Terms you also accept the DPA on behalf of the Customer.
9. Confidentiality
9.1 Each party may receive non-public information of the other ("Confidential Information"). The receiving party will use it only to perform under the Agreement and will protect it with at least reasonable care. Confidential Information does not include information that is public through no fault of the receiving party, independently developed, or rightfully received from a third party. This Section does not override the DPA for personal data.
10. Warranties and disclaimers
10.1 Each party warrants that it has the authority to enter into the Agreement.
10.2 Disclaimer. Except as expressly stated in the Agreement and to the fullest extent permitted by law, the Service is provided "AS IS" and "AS AVAILABLE", without warranties of any kind, whether express, implied, or statutory, including any implied warranties of merchantability, fitness for a particular purpose, non-infringement, or that the Service will be uninterrupted, timely, secure, or error-free. Free-tier and beta features are provided with no warranties and no service commitments of any kind.
10.3 Nothing in this Section excludes warranties or liability that cannot be excluded under mandatory Spanish or EU law.
11. Limitation of liability
11.1 Excluded damages. To the fullest extent permitted by law, neither party will be liable for any indirect, incidental, special, consequential, or punitive damages, or for lost profits, lost revenue, lost or corrupted data, or business interruption, even if advised of the possibility.
11.2 Cap. To the fullest extent permitted by law, each party's total aggregate liability arising out of or relating to the Agreement will not exceed the total fees paid or payable by you to us for the Service in the twelve (12) months immediately preceding the event giving rise to the liability. For the Free Plan or where no fees were paid, the aggregate cap is one hundred euro (€100).
11.3 Carve-backs. Nothing in this Section limits or excludes liability that cannot be limited or excluded under mandatory law, including liability for: (a) fraud or fraudulent misrepresentation; (b) wilful misconduct or intent (dolo); (c) gross negligence (culpa grave); (d) death or personal injury caused by negligence; and (e) any other liability that Spanish or EU law does not permit to be limited. The exclusions and cap in this Section apply only to the extent permitted for such matters.
11.4 The allocation of risk in this Section is a fundamental basis of the bargain between the parties and reflects the fees charged.
12. Indemnity
12.1 You will defend, indemnify, and hold us harmless from third-party claims, damages, and reasonable costs (including reasonable legal fees) arising out of (a) Customer Content, (b) your use of the Service in violation of the Agreement or applicable law, or (c) your breach of Section 5.4 or the AUP. We will promptly notify you of the claim, give you control of the defense (subject to our right to participate with our own counsel), and reasonably cooperate. This Section is subject to the limitations in Section 11 and to mandatory law.
13. Suspension
13.1 We may suspend or restrict all or part of your access to the Service, immediately and without prior notice where appropriate, if: (a) required by law or a competent authority; (b) your use poses a security risk to, or may adversely affect, the Service, us, other customers, or third parties; (c) your use violates the AUP or is fraudulent, abusive, or illegal; or (d) you fail to pay fees when due (subject to the grace period in Section 4.7).
13.2 We will use reasonable efforts to limit a suspension to what is necessary and to restore access once the cause is resolved. Where practicable and lawful, we will notify you of the reason and how to resolve it.
14. Term and termination
14.1 Term. The Agreement starts when you first accept it and continues while you have an account or an active subscription.
14.2 Termination for convenience. You may stop using the Service and close your account at any time from the dashboard or by contacting us. Closing your account does not entitle you to a refund except as provided in Section 4.3.
14.3 Termination for cause. Either party may terminate the Agreement for material breach by the other if the breach remains uncured 30 days after written notice describing it. We may terminate immediately (without a cure period) for the circumstances that justify immediate suspension under Section 13.1 or the AUP.
14.4 Effect of termination. On termination or expiry: (a) your right to access the Service ends; (b) accrued payment obligations survive; and (c) we will make Customer Content available for export for 30 days after termination (the "Retention Window"), after which we will delete Customer Content from active systems and purge it from backups on our normal backup-expiry cycle, except where retention is required by law. Deletion of personal data is further governed by the DPA.
14.5 Survival. Sections that by their nature should survive (including 5.6, 9, 10, 11, 12, 15, and 16) survive termination.
15. Changes to these Terms
15.1 We may update the Agreement. For changes that materially affect your rights or obligations, we will give at least 30 days' prior notice by email or in-product before they take effect. Non-material changes (for example, clarifications or legally required updates) may take effect sooner.
15.2 If you do not accept a material change, you may terminate your subscription before it takes effect; continued use of the Service after the effective date constitutes acceptance. Each version of the Terms is dated and archived.
16. Service levels
16.1 We do not offer a contractual service-level agreement (SLA) or uptime guarantee under the current Plans. We use commercially reasonable efforts to keep the Service available and may publish service status information. We reserve the right to introduce an SLA for specific Plans in the future.
17. Force majeure
17.1 Neither party is liable for failure or delay caused by events beyond its reasonable control, including natural disasters, war, terrorism, civil disturbance, labour disputes, failures of third-party networks or infrastructure, and acts of government. Payment obligations are not excused by this Section.
18. Governing law and jurisdiction
18.1 The Agreement is governed by the laws of Spain, without regard to conflict-of-laws rules.
18.2 The parties submit to the exclusive jurisdiction of the courts of the city of Barcelona, Spain (including, where competent, the Juzgados de lo Mercantil de Barcelona), except that either party may seek injunctive or interim relief in any court of competent jurisdiction. This Section does not deprive you of any protection of mandatory law that cannot be derogated from by agreement.
19. General
19.1 Assignment. You may not assign the Agreement without our prior written consent. We may assign it to an affiliate or in connection with a merger, acquisition, or sale of assets, on notice to you.
19.2 Entire agreement. The Agreement is the entire agreement between the parties on its subject matter and supersedes prior discussions and agreements. Any purchase-order or vendor terms you issue are rejected and have no effect.
19.3 Severability. If any provision is held unenforceable, the rest remains in effect and the unenforceable provision will be modified to the minimum extent necessary to make it enforceable.
19.4 Waiver. A failure to enforce a provision is not a waiver of it.
19.5 Notices. We may give notice by email to your account address or by posting in the Service. You may give notice to us at support@airstrings.com. Legal notices to us should reference "Legal Notice" in the subject.
19.6 Independent contractors. The parties are independent contractors; the Agreement creates no partnership, agency, or joint venture.
19.7 Language. These Terms may be provided in English and other languages. If a translation is provided and there is a conflict, the English version prevails, except where mandatory law requires otherwise.
