These Terms govern your use of InboxGuard. We’re launching with the Starter and Individual plans; additional tiers will be added as they become available, under these same Terms. If a line is unclear or you think it needs changing, tell us and we’ll rewrite it.

The short version
Five things to know in thirty seconds.
Full details in the sections below.
Phased plan rollout
Starter and Individual are live today. Other plans — including Family, which has its own addendum — are on the waitlist and will be covered by these Terms when they launch.
Cancel any time
Subscriptions can be cancelled from your account’s billing portal. No phone call, no retention team.
Plan limits are clear
Each plan has a stated monthly scan limit — listed on the pricing page, not hidden in fine print.
Your data is yours
We don’t claim your content. You can delete your account and revoke access at any time.
Good-faith terms
No hidden clauses or arbitration-only gotchas. If something changes, we’ll tell you and explain why.
01 · Agreement
By using InboxGuard, you agree to these terms.
These Terms of Service (the “Terms”) form a binding agreement between you and InboxGuard (the “service”, “we”, “us”). They apply every time you create an account, connect a mailbox, or use any feature of the product.
If you’re using InboxGuard on behalf of an organisation, you confirm you have authority to accept these Terms for that organisation — and “you” in this document means both you personally and the organisation.
In plain EnglishSigning up, connecting a mailbox, or clicking around the dashboard counts as agreeing. If you don’t agree with something below, don’t use the service — or email us and tell us what needs to change.
02 · The service
What InboxGuard actually is.
InboxGuard is an email-intelligence service. It connects to your inbox — Gmail, Microsoft 365 / Outlook, or an IMAP-compatible mailbox — using the smallest scope that lets it read messages and add or remove labels. It never sends mail as you and never permanently deletes messages. It analyses incoming mail for phishing, impersonation, credential theft, and scams, and presents verdicts in a dashboard. The full mechanics — what scope we use per provider, what we keep, what we discard — are covered in the Privacy Policy.
InboxGuard is offered as a paid subscription. Plans are launching in phases — available plans and limits are listed on the pricing page; other plans are on a waitlist. Specific features, limits, and integrations may change as we ship new versions; material changes will be communicated in advance (see §16).
03 · Your account
Who can sign up, and what you’re responsible for.
Eligibility
You must be at least 18 years old to create your own InboxGuard account — an account is a service contract with us, and we ask the same minimum as the payment processors that handle your subscription. If you are under 18, a parent or guardian can add you as a member of their Family plan; in that case the parent or guardian is the account holder and the Family Plan Addendum sets out the rules for processing a minor’s mailbox. Some jurisdictions impose stricter local minimums, and those apply where they are higher.
Accurate information
Give us accurate sign-up information (email, name, billing details) and keep it up to date. If something changes, update it in Settings.
Account security
You’re responsible for safeguarding your account credentials. Enable two-factor authentication when offered. Tell us right away through our contact page if you notice suspicious activity — unauthorised mailbox connections, unexpected billing, or a session you didn’t start.
One account per person
Personal plans are for a single human and the mailboxes they personally control. Family plans are intended to cover the members described on the pricing page. Don’t create multiple accounts to work around plan limits — get in touch via the contact page if your needs are larger and we’ll talk about it.
If you are using a Family plan to connect an inbox belonging to another person (a spouse, an elderly relative, or most importantly a minor in your care), additional terms apply. See our Family Plan Addendum for guardian responsibilities, consent requirements, and the rules around processing a child’s email data.
04 · Acceptable use
What you can and can’t do with the service.
InboxGuard is built to protect your inbox. To keep it working for everyone, these uses are off-limits:
You can
Connect mailboxes you personally own or are authorised to manage
Use verdicts to decide how to handle your own mail
Export your data at any time, in JSON
Share dashboard screenshots publicly (redact at your discretion)
Cancel or delete your account without asking us
You can’t
Connect mailboxes that aren’t yours or you lack consent to scan
Resell, rebrand, or white-label the service without written agreement
Scrape the API, dashboard, or verdicts for bulk commercial use
Reverse-engineer or copy the detection pipeline
Use verdicts to harass senders or automate retaliation
Circumvent quotas, rate limits, or paid-plan gates
If you’re not sure whether something you want to do is acceptable, use the contact page and describe it. We’d rather say yes and know about it than find out after.
05 · Plans & billing
How subscriptions, renewals, and quotas work.
Paid plans
InboxGuard is sold on monthly or annual subscriptions. Prices, features, and monthly scan limits for available plans are listed on the pricing page. The price shown at checkout is the price you pay for that term.
Renewals
Subscriptions are expected to renew automatically at the end of each term at the then-current rate for your plan, unless cancelled. We’ll send reasonable advance notice before each renewal so you can cancel or change plans if you want to.
Plan limits
Each plan has a monthly scan limit — see the pricing page for current figures. When you reach your monthly limit, scanning pauses until your next billing cycle or until you upgrade. We don’t charge overages and we don’t scan past your limit.
Taxes
Prices exclude VAT, GST, or sales tax unless otherwise stated. Applicable taxes are added at checkout based on your billing address and collected by our payment processor.
Refunds
Refund requests are reviewed on a case-by-case basis. Contact us through the contact page with the details and we’ll respond in good faith. Statutory consumer rights in your jurisdiction (e.g. the UK/EU 14-day cooling-off period for distance sales, where it applies) are preserved regardless of anything in these Terms.
06 · Cancellation & account deletion
You can leave at any time.
Cancelling a subscription
Paid subscriptions can be cancelled from your account’s billing portal. Cancellation stops the subscription from renewing — you keep access until the end of the paid period and aren’t billed again.
Deleting your account
You can delete your account from your account settings. Deletion revokes mailbox access (OAuth tokens or IMAP credentials), removes your stored scans, metadata, and rules, and closes the account. Billing records are retained only as required by applicable tax and accounting law and aren’t used for anything else (see the Privacy Policy for the full retention schedule).
Good to knowDeletion is final and we can’t recover data afterwards. Export anything you want to keep before you delete.
07 · Your content
You own your mail. Full stop.
InboxGuard processes content from your mailbox to deliver verdicts. Processing that content doesn’t transfer ownership. You own your email, your metadata, your reports, and your rules — always.
You grant us a limited licence to process your content only for the purpose of running the service: scanning, classifying, displaying verdicts to you, and — where you explicitly Report a misclassified message — improving detection. This licence ends when you delete the content or close your account. It never includes training AI models on your mail; see the Privacy Policy §07 for detail.
08 · Our IP
The product, brand, and detection pipeline are ours.
The InboxGuard service, dashboards, detection models, brand, logos, and website are our intellectual property or licensed to us. These Terms don’t grant you any rights in them beyond the right to use the service as intended.
You may take and share screenshots of your own dashboard for personal or journalistic purposes. Commercial reproduction of UI, copy, or marketing materials requires written permission (use our contact page).
Feedback
If you send us feedback, bug reports, or feature suggestions, we can use them freely to improve the product without owing you anything. (We’re still grateful — good feedback changes our roadmap.)
09 · Third-party services
The parts of the stack that aren’t us.
InboxGuard depends on third-party services to operate. When you use InboxGuard, you’re also relying on the terms of the ones you interact with directly:
Mailbox providers. Your connection to InboxGuard uses the smallest scope that lets us label and quarantine threats — Google OAuth (gmail.modify) for Gmail, Microsoft OAuth (Mail.ReadWrite) for Microsoft 365 / Outlook, or read-only IMAP credentials for other providers. We never send mail as you and never permanently delete messages. The provider’s own terms and privacy policy govern your mailbox account separately. You can revoke InboxGuard’s access at any time, either from the provider’s account settings or from your Connected Inboxes settings page — doing so stops scanning immediately.
Payment processors. Where you subscribe determines who handles the payment:
Stripe processes payments for subscriptions purchased on inboxguard.app on our behalf. Card details go directly to Stripe; we receive a token and billing status.
Apple (App Store) is the merchant of record for subscriptions purchased through in-app purchase on iOS. Apple processes the payment and holds your card details; we receive a receipt and entitlement status.
Google (Play Store) is the merchant of record for subscriptions purchased through in-app purchase on Android. Google processes the payment and holds your card details; we receive a receipt and entitlement status.
In all cases we never receive or store card numbers. Each processor’s own terms govern the payment transaction.
AI model providers. Our classifier calls commercial AI model APIs. We select providers whose terms prohibit training on API content and whose retention windows match our privacy commitments. See Privacy Policy for detail.
A current sub-processor list will be maintained in the Privacy Policy. We’ll notify registered users before adding a new sub-processor that handles personal data.
10 · Availability & changes to the service
We aim for always-on. We’ll be honest when we aren’t.
InboxGuard is a live service. We do our best to keep it available 24/7, but we don’t guarantee uninterrupted operation. Planned maintenance windows are announced in-app and on our status page; unplanned incidents are posted there as soon as we know.
We may add, change, or remove features. For changes that materially reduce functionality on a plan you’re paying for, we’ll notify you in advance and offer a refund or plan migration if appropriate.
Worth knowingIf we ever wind the service down, we’ll give reasonable advance notice, let you export your data, and refund any prepaid subscription time on a pro-rata basis.
Payment fails and remains unpaid after reasonable notice
We’re legally required to
We have good-faith reason to believe the account poses a safety or fraud risk to others
Where possible we’ll warn you first and give you a chance to fix the issue. For non-urgent suspensions we’ll tell you why and what would unblock the account.
On termination, your access ends and we delete account data per the retention schedule in the Privacy Policy. You can always terminate your own account via Settings without notice to us.
12 · Disclaimers
What InboxGuard is not.
InboxGuard is a decision-support tool, not a guarantee. We try hard to catch phishing and scams, but no email security product catches everything, and attackers adapt. You’re the final decision-maker on every email — that’s why our verdicts are advisory and never auto-delete or auto-archive.
To the maximum extent permitted by law, the service is provided “as is” and “as available”. We disclaim implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We don’t warrant that the service will be error-free, uninterrupted, or that every threat will be caught. Statutory rights that can’t be waived (e.g. consumer protections in your jurisdiction) still apply.
13 · Limitation of liability
The practical caps on what each side can claim.
To the maximum extent allowed by law, neither party is liable for indirect, incidental, special, consequential, or punitive damages, including lost profits, lost revenue, lost data, or business interruption — even if advised of the possibility.
Our total aggregate liability arising out of or related to these Terms or the service is capped at the fees you paid us in the twelve months before the event giving rise to the claim. If you paid us nothing, our liability to you in that period is limited to the maximum amount permitted by law in your jurisdiction.
Some jurisdictions don’t allow these limits, in which case they apply to the fullest extent permitted. Nothing in this section limits liability for fraud, gross negligence, willful misconduct, or anything else that can’t be limited by law.
14 · Indemnity
If someone sues one of us because of the other, who pays.
You’ll indemnify and hold us harmless from claims, losses, and expenses (including reasonable legal fees) arising from your breach of these Terms, your content, or your misuse of the service. We’ll cooperate at your reasonable expense in defending any such claim and you won’t settle anything that affects us without our prior written consent.
This is a fairly standard clause for SaaS contracts. It doesn’t apply to typical consumer use of the service — we include it to handle edge cases (e.g. an organisation connecting mailboxes it didn’t have consent to scan).
15 · Governing law & disputes
How we resolve disagreements.
Governing law and jurisdiction. These Terms are entered into between you and InboxGuard Ltd, a company registered in England and Wales. They are governed by the laws of England and Wales, and the courts of England and Wales have non-exclusive jurisdiction over any dispute arising from them — subject to the mandatory consumer protections below.
Informal resolution first. Before filing anything formal, please contact us via our contact page. We’ll try to resolve it directly and in good faith.
Mandatory consumer protections. Consumers in the UK, EU, and other jurisdictions with mandatory local consumer protections retain the right to bring a claim in the courts of their place of residence, and the law of that place applies to those mandatory protections. Nothing in these Terms overrides those rights.
16 · Changes to these terms
What happens when the contract changes.
These Terms will evolve as the service launches publicly and matures. For material changes — anything that meaningfully affects your rights, fees, or how your data is handled — we’ll give registered users reasonable advance notice by email and in-app banner, so you can review and close your account before the changes take effect if you don’t accept them. Continued use after the effective date means you accept the updated Terms.
Non-material changes (typo fixes, clarifications, re-numbering, adding a new sub-processor to the Privacy Policy list) take effect when published.
The effective date at the top of this page reflects the latest version. Every version and a short note on what changed is listed below.
