Terms of Service

Last updated: May 14, 2026 · Effective: May 14, 2026

1. The Service

Mittr™ is a webhook delivery platform. The Service accepts events from your applications, persists them, signs each outbound request with a per-endpoint secret you control, delivers them to destination URLs you configure, retries on failure according to the policy you set, surfaces delivery observability, and supports inbound webhook reception with verification and fan-out. Feature availability depends on your subscription plan.

You direct delivery; we execute it. You are responsible for the destination URLs you configure, the contents of payloads you submit, your relationship with the operators of destination endpoints, and the lawful basis on which you process any personal data inside those payloads. Mittr does not endorse, screen, or moderate webhook content; we deliver what you ask, to where you ask, on the schedule you ask.

We do not read payload contents for any purpose other than delivering them and producing the delivery telemetry you see in your dashboard. We do not analyse, index, train models on, or otherwise derive intelligence from the bodies of your events. We do not share payload contents with any party other than the destination URLs you configure or, where required, lawful authorities (see section 13 and the Privacy Policy). If we ever add features that require analysing payload contents (for example, an opt-in AI-assisted classification or anomaly-detection capability), participation will be explicit and opt-in, and we will update these Terms before activating that processing.

2. Your account

2.1 Registration

• You must provide accurate, complete, and current information when creating an account, and keep it updated.
• You must be at least 16 years old, or the minimum age of digital consent in your jurisdiction, whichever is higher.
• You are responsible for safeguarding your password, API keys, MFA secrets, and any session tokens issued to you. You must notify us at [email protected] immediately if you discover or suspect any unauthorised use of your account.
• You are responsible for all activity that occurs under your account, including actions by team members or anyone with valid credentials.

2.2 Workspaces + teams

• A workspace is the top-level container for a tenant's data on Mittr. The first user to sign up for a workspace becomes its Owner.
• The Owner can invite team members and assign roles (Admin, Editor, Viewer). Each role has specific capabilities documented in the dashboard.
• The Owner is contractually responsible for the workspace's compliance with these Terms. Workspace admins have authority to act on the Owner's behalf for most operational matters.

3. Acceptable use

You will not, and will not allow any person to, use Mittr in any of the following ways. These rules are specific to webhook delivery; we've called out the failure modes a webhook infrastructure provider sees most often.

3.1 Destination ownership + consent

• You will only configure destination URLs that you own, operate, or have explicit permission from the operator to deliver to.
• You will not use Mittr to send unsolicited webhooks, push notifications, or other automated traffic to endpoints whose operators have not consented to receive them.
• You will not impersonate other senders by spoofing source identifiers, forging signatures intended to imitate a different system, or otherwise misrepresenting the origin of an event.
• The Mittr-issued HMAC signature on outbound deliveries attests that the event passed through Mittr — it does not certify the content as accurate, lawful, or non-malicious.

3.2 Payload content

• You will not submit payloads containing malware, phishing content, exploit payloads, ransomware, or any code intended to compromise the destination system or the systems it interacts with.
• You will not submit payloads that are unlawful in the jurisdictions of the sender, the destination operator, or Mittr — including content that is defamatory, fraudulent, infringes intellectual property, harasses, incites violence, or sexualises minors.
• You will not submit payloads designed to exploit deserialisation, SQL injection, command injection, SSRF, or similar vulnerabilities in destination systems.
• You are responsible for ensuring you have all consents required by data-protection law for any personal data you place inside webhook payloads. Mittr is your processor for that data; you are the controller.

3.3 Traffic patterns + abuse

• You will not use Mittr to direct high-volume traffic at a single destination in a manner that constitutes a denial-of-service or amplification attack.
• You will not bypass, evade, or attempt to circumvent rate limits, per-endpoint concurrency caps, retry-backoff policies, or circuit-breaker behaviour built into the Service.
• You will not deliberately configure delivery to private, internal, or reserved IP ranges to probe internal networks via Mittr's egress. Mittr applies SSRF protection by default; you will not seek ways around it.
• You will not deliberately configure delivery to URLs you know are non-responsive in order to exercise the retry / dead-letter / replay machinery in a way that imposes disproportionate cost on the Service.

3.4 Account, credentials + workspace boundaries

• You will treat API keys, signing secrets, mTLS client keys, SAML SP private keys, and session cookies as sensitive credentials. You will not share, log to insecure channels, or commit them to source control.
• You will not attempt to access another customer's data, workspace, sub-account, or audit log.
• You will not register accounts using disposable email addresses, stolen identities, or in evasion of a prior account suspension.
• You will not engage in webhook-routing arbitrage where the same event is intentionally amplified through multiple workspaces or accounts to evade plan limits.

3.5 Platform integrity

• You will not reverse-engineer, decompile, or disassemble the Service except where applicable law permits and where you cannot achieve the same outcome through documented APIs.
• You will not probe, scan, or test the Service's security except via the coordinated disclosure process: email [email protected] with subject "Security" before testing.
• You will not harvest other Mittr users' identifying information; will not attempt to de-anonymise aggregated telemetry; will not use scraping or automation against the Service in violation of these Terms.
• You will not use the Service in a manner that is prohibited by applicable export, sanctions, or human-rights law.

3.6 Suspension pending investigation

We may temporarily suspend account access while we investigate conduct that appears to violate this AUP. Where reasonable, we will notify you and give you an opportunity to respond before finalising any suspension or termination. Where the conduct poses immediate risk to Mittr, to other customers, or to destination operators, suspension may be immediate.

4. Plans, payment + taxes

4.1 Free + paid plans

• The Free plan is available at no cost, subject to the limits described on the pricing page and enforced in product.
• Paid plans are billed in advance, monthly or annually. Plan features and limits are described on the pricing page.
• Overage fees, where applicable, are billed in arrears based on metered usage that exceeds plan caps.

4.2 Merchant of Record

Paid subscriptions and overage charges are sold and processed by Paddle.com Inc. (or its applicable affiliate) acting as our Merchant of Record. Paddle is the seller of record for your transaction, issues the receipt or VAT invoice, and is responsible for collecting and remitting any applicable sales tax, VAT, or GST in your jurisdiction.

Your contractual relationship for the Service itself remains with Silven Dynamics; Paddle is the payment counterparty only. Paddle's customer terms apply to the payment transaction in addition to these Terms; in the event of conflict, the section governing the payment transaction itself is controlled by Paddle's terms, while everything else remains governed by these Terms.

4.3 Taxes

Prices are shown in USD. At checkout, Paddle calculates any applicable VAT, GST, or sales tax based on your billing location and presents the total before payment — either added on top of the listed price (e.g. United States, Canada) or already included in the listed price (e.g. most of Europe, Australia, New Zealand), in line with local pricing conventions. Paddle handles tax registration, collection, and remittance in jurisdictions where it is the registered seller.

4.4 Payment failures

• If a payment fails, Paddle will retry according to its dunning policy. Persistent failure may result in your subscription being canceled and your plan reverting to Free, with Free-plan limits applying immediately.
• You remain liable for unpaid fees and any reasonable collection costs.

4.5 Refunds

Refund requests are administered through Paddle but follow our refund policy: all fees are non-refundable except where required by applicable law. We do not pro-rate downgrades or cancellations within a billing cycle; you retain access to the higher tier through the end of the paid period. To request a refund, contact [email protected].

4.6 Price changes

We may change pricing with at least 30 days' notice. Existing paid subscriptions complete their current billing cycle at the original price; the new price applies at the next renewal. You may cancel before the renewal if you do not accept the new price.

5. Your content + data

• You retain all rights, title, and interest in and to the data you submit through the Service ("Customer Data"), including webhook event payloads, endpoint configurations, team metadata, and account information.
• You grant Silven Dynamics a worldwide, non-exclusive, royalty-free licence to host, store, process, transmit, and display Customer Data solely as necessary to provide the Service to you, comply with legal obligations, and improve the Service (using aggregated, de-identified data only).
• You represent and warrant that you have all rights and consents required to submit Customer Data through the Service, including any consents required from end-users whose personal data appears in your webhook payloads.
• Our handling of personal data within Customer Data is governed by our Privacy Policy and our Data Processing Addendum (available on request from [email protected]).

6. Service availability + beta status

6.1 Beta

Mittr is currently designated as Beta. During the beta period:

• We do not commit to a contractual uptime SLA. We aim for high availability and take reliability seriously, but you should not depend on Mittr for mission-critical traffic without your own fallback.
• We may introduce breaking changes to the API or dashboard with at least 30 days' notice (less in security emergencies).
• The Service may experience extended maintenance windows that would not be acceptable at general-availability.
• Features may be added, removed, or changed without long deprecation periods.

6.2 Post-beta

Once Mittr exits beta, the plan-specific SLA terms published on the pricing page will become contractual. We will update these Terms accordingly with at least 30 days' notice.

6.3 Maintenance + scheduled downtime

We perform routine maintenance and security patching that may cause brief service interruption. Where reasonably possible, we will announce planned maintenance in advance via status page, email, or in-product notice. Emergency maintenance may proceed without prior notice.

7. Intellectual property

• The Service, including all software, designs, documentation, copy, logos, and trademarks, is the exclusive property of Silven Dynamics, its licensors, and its suppliers. All rights not expressly granted to you are reserved.
• Mittr™, the Mittr name, the Mittr wordmark, and the Silven Dynamics name and logo are trademarks of Silven Dynamics. See section 10 for limited permitted uses.
• The Service's source code, documentation, designs, illustrations, and marketing materials are copyrighted © 2026 Silven Dynamics. All rights reserved.
• You receive no licence to our intellectual property other than the limited right to use the Service in accordance with these Terms.

8. Third-party services

The Service may interoperate with third-party services that you configure (e.g., a Slack webhook destination, a Stripe webhook source, a custom HTTP endpoint). Your use of those services is governed by your relationship with the third party. We are not responsible for third-party services and do not endorse them simply because they are reachable from Mittr. If a third-party service injures you, your recourse is against that third party, not us.

Open-source dependencies in the Service are subject to their respective licences. A list of major dependencies is available on request.

9. Feedback

If you provide feedback, suggestions, feature requests, or any other input about the Service ("Feedback"), you grant Silven Dynamics a perpetual, irrevocable, royalty-free, worldwide licence to use the Feedback for any purpose without attribution or compensation. We are not obligated to act on Feedback.

10. Trademark + branding use

Permitted uses of the Mittr™ name and wordmark:

• Stating in good faith that you use Mittr for webhook delivery, in product copy, on your website, in case studies, in resumes.
• Referring to Mittr in editorial content (articles, tutorials, comparison reviews).

Prohibited uses:

• Using "Mittr" or our wordmark as part of your own product or company name in a way likely to confuse buyers.
• Claiming endorsement, partnership, or affiliation with Silven Dynamics that doesn't exist.
• Modifying the wordmark, our colours, or our visual identity in any branded material.
• Using the trademarks in a way that disparages Silven Dynamics, Mittr, or our employees, partners, or customers.

11. IP infringement notifications

If you believe content delivered through the Service infringes your intellectual property rights, please send a notice to [email protected] with the subject "IP Notice". Include:

• Your identifying information and a way to contact you.
• The specific work claimed to be infringed.
• The specific material claimed to be infringing, with sufficient detail (timestamps, event IDs, destination URL).
• A statement, under penalty of perjury, that you have a good-faith belief the use is unauthorised and that the information in your notice is accurate.
• An electronic signature.

We will investigate good-faith notices and may suspend account access pending resolution. We follow DMCA-equivalent procedures where applicable and reserve the right to pass notices on to the alleged infringer.

12. Suspension + termination

12.1 By you

You may cancel your account at any time from the dashboard. Cancellation takes effect at the end of the current billing cycle for paid plans, or immediately for Free. Cancellation does not refund pre-paid fees except where required by law.

12.2 By us

We may suspend or terminate your account at any time, with or without notice, in the following cases:

• Material breach of these Terms (including the AUP) by you.
• Unpaid fees beyond a 30-day grace period.
• Prolonged inactivity (12 months or more on Free plan with no signups, signins, or events).
• Use that creates legal, security, or reputational risk for the Service or its users.
• Required by law, court order, or regulator request.

Where the breach is non-emergency and curable, we will normally give notice and a reasonable opportunity to cure before terminating. Termination for non-payment generally follows a payment-failure retry cycle with multiple notifications.

12.3 Effect of termination

• Your access to the Service ends.
• We retain Customer Data for the period described in the Privacy Policy to allow recovery or comply with legal obligations, then delete it.
• Pre-paid fees for the post-termination period are non-refundable except where required by law.
• Provisions that by their nature should survive termination (e.g., IP, indemnity, liability, governing law) survive (see section 23).

13. Disclaimers

The Service is provided "AS IS" and "AS AVAILABLE" without warranties of any kind, whether express, implied, statutory, or otherwise. To the maximum extent permitted by applicable law, Silven Dynamics disclaims all warranties, including warranties of merchantability, fitness for a particular purpose, title, and non-infringement.

We do not warrant that the Service will be uninterrupted, free of errors, free of viruses or harmful components, or that all events will be delivered to all destinations. We do not warrant that any defect will be corrected. Your use of the Service is at your own risk.

14. Limitation of liability

To the maximum extent permitted by applicable law, in no event will Silven Dynamics, its affiliates, officers, employees, or suppliers be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, including damages for loss of profits, revenue, business interruption, loss of data, or goodwill, arising out of or relating to the Service or these Terms, even if Silven Dynamics has been advised of the possibility of such damages.

Silven Dynamics's total cumulative liability for any claim arising out of or relating to the Service or these Terms is limited to the greater of (a) the fees you actually paid Silven Dynamics in the 12 months preceding the event giving rise to the claim, or (b) USD 100.

Some jurisdictions do not permit the limitation or exclusion of certain damages. In those jurisdictions, the limitations above apply to the maximum extent permitted by law.

15. Indemnification

You will defend, indemnify, and hold harmless Silven Dynamics, its affiliates, officers, employees, and suppliers from and against any third-party claims, damages, liabilities, costs, and expenses (including reasonable legal fees) arising out of or related to (a) your breach of these Terms, (b) your violation of any law or third-party right, (c) your Customer Data, including any personal-data processing for which you are the controller, or (d) your use of the Service in any way not permitted by these Terms.

We will promptly notify you of any covered claim and give you reasonable assistance in defending it. You may not settle any claim that admits liability or imposes an obligation on Silven Dynamics without our written consent.

16. Export controls + sanctions

You will comply with all applicable export, re-export, sanctions, and import laws that apply to you, to Silven Dynamics, or to your use of the Service. You represent that you (and any end-users you give access to the Service) are not (i) located in a country subject to comprehensive sanctions, or (ii) named on any applicable restricted-party or sanctions list maintained by a competent government authority (including, by way of example, the US Treasury's OFAC SDN list, the EU Consolidated Financial Sanctions List, and the UK HM Treasury Consolidated List).

17. Anti-bribery + anti-corruption

You will not, in connection with these Terms or the Service, offer, give, solicit, or accept any bribe, kickback, or improper benefit. You will comply with all applicable anti-bribery and anti-corruption laws, including (where applicable to you) the US Foreign Corrupt Practices Act, the UK Bribery Act, and any equivalent legislation in your jurisdiction.

18. Force majeure

Neither party is liable for failure or delay in performance caused by circumstances beyond reasonable control, including acts of God, natural disasters, pandemics, war, terrorism, civil unrest, government action, infrastructure failure (internet backbone outages, major cloud-provider outages), labour disputes, or other events of force majeure. The affected party will use reasonable efforts to resume performance promptly.

19. Changes to these Terms

We may update these Terms from time to time. The "Effective" date at the top reflects the current version.

For material changes — for example, new fees, expanded restrictions on use, or changes to limitation of liability — we will notify active account holders by email at least 30 days before the change takes effect. Continued use of the Service after the effective date constitutes acceptance of the updated Terms.

Non-material changes (typos, clarifications, formatting) take effect immediately on publication.

20. Assignment

You may not assign or transfer these Terms or any rights under them without our prior written consent. Any attempted assignment without consent is void. We may assign these Terms in connection with a merger, acquisition, sale of substantially all our assets, or restructuring, on notice to you.

21. Notices

• To you: notices we give will be sent to the email address associated with your account and/or shown in the Service. You are responsible for keeping your contact information current.
• To us: legal notices must be sent to [email protected] with subject "Legal Notice". Physical address for service of process will be provided on request to enterprise customers under a signed contract.

22. Entire agreement, severability, waiver

• Entire agreement. These Terms, together with the Privacy Policy and any DPA, Order Form, or other written agreement we sign with you, constitute the entire agreement between you and Silven Dynamics regarding the Service. They supersede any prior or contemporaneous agreements, communications, or proposals.
• Severability. If any provision of these Terms is held unenforceable, the remaining provisions remain in full force and effect. The unenforceable provision will be modified to the minimum extent necessary to make it enforceable while preserving its intent.
• No waiver. Our failure to enforce any right or provision is not a waiver of that right or provision in the future.
• No partnership. Nothing in these Terms creates a partnership, joint venture, agency, or employment relationship between you and Silven Dynamics. Neither party has authority to bind the other.
• Third-party beneficiaries. Except as expressly stated, these Terms confer no rights on any third party.

23. Survival

Provisions that by their nature should survive termination of these Terms will survive, including sections 5 (Your content), 7 (IP), 9 (Feedback), 13 (Disclaimers), 14 (Limitation of liability), 15 (Indemnification), 22 (Entire agreement, severability, waiver), 24 (Governing law + disputes), and any payment obligations you have incurred.

24. Governing law + disputes

These Terms are governed by and construed in accordance with the laws of the Republic of Kenya, without regard to its conflict-of-laws principles. The UN Convention on Contracts for the International Sale of Goods does not apply.

Any dispute arising out of or in connection with these Terms will be resolved exclusively in the competent courts of the Republic of Kenya, except where mandatory consumer-protection law in your jurisdiction grants you a different forum.

Before initiating formal proceedings, the parties will attempt in good faith to resolve any dispute by negotiation, escalating promptly to the parties' senior leaders. Either party may pursue urgent injunctive or equitable relief in any competent court without first negotiating.
