Terms of Use

These Terms of Use ("Terms") form a binding agreement between you ("Customer", "you") and SieveGuard ("SieveGuard", "we"). By creating an account or using the Service, you agree to these Terms.

1. Definitions

• Service: the SieveGuard email-integrity API and associated console at https://sieveguard.com.
• Plan: the published subscription tier you select.
• Subscription: your active billing arrangement with us.
• Trial: the platform-wide free-trial window applied to every new account.

2. Acceptance and changes

Continued use of the Service after we publish updated Terms constitutes acceptance. Material changes are notified to the email on file at least 30 days before they take effect.

3. Account registration

You must provide accurate information and keep your credentials secure. You are responsible for all activity under your account.

4. Subscriptions and billing

Subscriptions renew automatically at the end of each billing period (monthly or annual) until cancelled. Listed prices exclude VAT; Stripe Tax computes and adds any applicable VAT line at checkout based on your billing country and VAT-ID status (see §13). Annual plans are 10% off the monthly equivalent, and your first annual invoice receives a one-time welcome bonus equal to two months free (applied as a Stripe coupon on that invoice only — renewals charge the standard 10%-off annual rate). Payments are processed by Stripe; failed payments may suspend the Service until resolved.

Add-on charges & credit packs. In addition to your recurring Plan, you may purchase: (a) recurring add-ons — per-feature usage tiers billed as additional line items on your Plan invoice, pro-rated mid-cycle by Stripe; or (b) one-time credit packs — top-up balances of SieveGuard Credits charged immediately at checkout, non-recurring, with no cancellation or renewal. Purchased credits remain available until consumed and roll over month to month. Mid-cycle add-on upgrades may, at our discretion, be invoiced and collected immediately rather than accruing to your next regular invoice; you will always see the exact amount before confirming the change in the portal.

5. Free trial

New accounts may receive a free trial of the Service. No payment method is required during the trial. Access is automatically suspended at the end of the trial unless you subscribe to a Plan.

6. License grant

Subject to these Terms, we grant you a limited, revocable, non-exclusive, non-transferable license to use the Service solely for your own internal business purposes during your Subscription.

7. Restrictions

You may not:

• resell, sublicense, rent, lease, or distribute the Service to a third party;
• operate the Service as a timeshare, service-bureau, or white-label offering;
• reverse engineer, decompile or attempt to derive the source code;
• scrape, crawl, or otherwise access the Service except through documented APIs;
• circumvent quota, rate-limit, or trial enforcement;
• use the Service to build a competing product.

8. Acceptable use

Your use of the Service is bound by our Acceptable Use Policy. Breach of the AUP is grounds for immediate suspension without refund.

9. Customer data

You retain ownership of email data you submit to the Service. We process it as a Processor on your behalf under the Data Processing Agreement.

10. Service availability

We use commercially reasonable efforts to maintain Service availability. Specific uptime guarantees apply only where expressly stated in a separately-signed SLA.

11. Suspension and termination

We may suspend or terminate your access for non-payment, AUP breach, or violation of these Terms. You may terminate at any time from the Subscription page; access runs until the end of your current billing period.

12. Refund policy

13. Fees and taxes

Listed prices exclude VAT. The applicable VAT line, where any, is computed by Stripe Tax at checkout from your billing country and VAT-ID status:

• EU business customers with a valid VAT ID in a Member State other than ours pay no VAT — the reverse-charge mechanism applies (Council Directive 2006/112/EC, Art. 196) and you self-account for the tax in your own return.
• Same-country business customers (resident in the same Member State as us, with a domestic VAT ID) are charged the standard local VAT rate; you may reclaim it via your local VAT return.
• EU consumers (no VAT ID) are charged VAT at the rate of their country of residence under the Union One-Stop-Shop (OSS) scheme.
• UK customers are charged UK VAT in accordance with post-Brexit UK rules; UK businesses providing a valid UK VAT number are subject to reverse charge under HMRC guidance.
• Non-EU/UK customers are not charged VAT — the supply is treated as an export of services (Council Directive 2006/112/EC, Art. 44/59) and is outside the scope of EU VAT.

You are responsible for any other taxes due in your jurisdiction (income tax, sales tax, GST, withholding tax, etc.) and for keeping your billing country and VAT ID under Settings → Billing up to date so that VAT is computed correctly on each renewal.

14. Confidentiality

Each party agrees to protect the other's confidential information with at least the same degree of care used to protect its own, and no less than reasonable care.

15. Intellectual property

We retain all rights, title, and interest in the Service, including all software, documentation, and trademarks. You retain rights to your submitted data.

16. Warranties and disclaimers

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE". TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.

17. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, OUR TOTAL LIABILITY ARISING OUT OF OR RELATING TO THESE TERMS WILL NOT EXCEED THE FEES YOU PAID TO US IN THE 12 MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM. WE WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES.

18. Indemnification

You will indemnify us against third-party claims arising from your breach of these Terms, your AUP violations, or unlawful content you submit through the Service.

19. Governing law and jurisdiction

These Terms are governed by the laws of the jurisdiction where SieveGuard is established, without regard to conflict-of-laws principles. The courts of that jurisdiction have exclusive competence over disputes, except that either party may seek injunctive relief in any competent court. The applicable jurisdiction will be identified on request to [email protected].

20. Miscellaneous

These Terms, together with the Privacy Policy, DPA and AUP, are the entire agreement between us. If any provision is held unenforceable, the rest remains in effect. You may not assign these Terms without our written consent; we may assign them in connection with a merger or sale of substantially all our assets. Notices to us must be sent to [email protected].
