Terms of service.

What you can expect from us, and what we expect from you.

1. The agreement

These Terms of Service (the “Terms”) are a binding legal agreement between you and Momentarily (“Momentarily”, “we”, “us”, “our”), a business based in Manchester, United Kingdom. They govern your access to and use of the scheduling service available at momentarily.onlineand any associated web, email, or API surfaces (together, the “Service”).

By creating a Momentarily account, connecting a calendar, or otherwise using the Service, you confirm you have read and agree to these Terms and to our Privacy Notice, which forms part of this agreement. If you do not agree, you must not use the Service.

We may publish supplementary guidelines (for example, acceptable-use examples or feature-specific notes). Where those exist, they're part of this agreement too. In the event of a conflict, these Terms take precedence.

2. Eligibility and your account

  • Age. You must be at least 16 years old, or the age of digital consent in your country, whichever is higher. The Service is not designed for children.
  • Capacity.By using the Service you confirm you can form a binding contract under the law of your jurisdiction. If you're agreeing on behalf of an organisation, you confirm you have authority to bind that organisation and these Terms apply to it as “you”.
  • Account security.You're responsible for the acts and omissions of anyone who uses your account. Keep your sign-in credentials secure and notify us at hello@momentarily.online immediately if you suspect unauthorised access.
  • Accurate information. Provide truthful details when you sign up and keep them current. We may suspend or close accounts found to be impersonating someone else or registered under false pretences.
  • One human, one account. The free tier is metered per person. Creating multiple free accounts to bypass limits is a breach of these Terms.

3. What the Service does (and doesn't)

Momentarily helps hosts find times that work for their friends' calendars. We look at free/busy data only — never event titles, locations, attendees, or attachments. What you see inside the product is the source of truth about what we'll do with your data.

The Service is provided on a best-efforts basis. Scheduling suggestions depend on third-party calendars (Google, Apple iCloud) being accurate and reachable. When those services are slow, offline, or return stale data, results may too. We don't guarantee that any particular event, invitation, or reminder will be delivered or received on time.

We may add, remove, or change features at any time. Where a change materially reduces the Service for paying users we'll give reasonable notice (typically thirty days) before it takes effect, or offer a pro-rata refund.

4. Licence to use the Service

Subject to your compliance with these Terms, we grant you a limited, non-exclusive, non-transferable, revocable licence to access and use the Service for your personal, non-commercial scheduling (or, if you're a paying business account, for internal business scheduling). This licence does not grant you any ownership of the Service or the underlying software, designs, or brand.

You agree not to:

  • copy, modify, translate, or create derivative works of the Service, except as permitted by mandatory law;
  • reverse-engineer, decompile, or disassemble the Service, except where applicable law expressly permits it;
  • scrape, crawl, bulk-extract, or harvest data from the Service, or use any automation we haven't authorised;
  • rent, sell, sublicense, resell, or otherwise commercially exploit the Service or any part of it without our prior written consent;
  • remove, obscure, or alter any copyright, trademark, or other proprietary notices in the Service;
  • use the Service in a way that would cause Momentarily to breach its agreements with Google, Apple, Stripe, or any other integration partner.

5. Acceptable use

You must not use the Service to do anything unlawful, harmful, or intrusive. Specifically, you agree not to:

  • break any applicable law or regulation, or infringe anyone's rights (including privacy, publicity, IP, or data-protection rights);
  • upload or transmit malware, viruses, worms, or other malicious code;
  • attempt to gain unauthorised access to other users' accounts, data, or calendars, or to our systems or infrastructure;
  • send spam, unsolicited marketing, or repeat invitation links to people who have not asked to receive them;
  • use the Service to harass, stalk, threaten, or defame anyone;
  • interfere with or disrupt the Service, including by overwhelming it with requests, probing for vulnerabilities without permission, or circumventing our rate limits;
  • impersonate any person or entity, or misrepresent your affiliation with a person or entity;
  • submit a plan or connect a calendar containing information you don't have the right to submit.

We may, in our reasonable discretion, investigate suspected breaches. If we conclude you've broken these Terms we may warn you, limit features, suspend your account, or terminate your access — with or without notice, depending on the severity of the breach and the risk to other users.

6. Your content

You keep ownership of everything you submit to the Service — group names, plan titles, the free-text fields you fill in, the guests you add. We call this “Your Content”.

To run the Service, you grant us a worldwide, non-exclusive, royalty-free licence to host, store, reproduce, transmit, display, and create derivative works of Your Content solely for the purpose of operating, maintaining, and improving the Service for you and the people you've chosen to share it with. This licence ends when Your Content is removed from the Service, except to the extent we're required by law to retain it, or where removal is not technically feasible (for example, redundant encrypted backups that rotate out on a schedule).

You're responsible for Your Content and must have all necessary rights to submit it. We may remove content that violates these Terms, applicable law, or a third-party partner's acceptable-use policy.

7. Third-party services and calendars

The Service integrates with Google Calendar, Apple iCloud (via public ICS feeds), Stripe, and other providers. Your use of those services is governed by each provider's own terms, which you must comply with. Momentarily is not responsible for the acts, omissions, availability, or accuracy of third-party services.

If a provider terminates our integration, changes its API, or suspends your account with them, we may not be able to provide corresponding features in Momentarily. Where this materially affects paid features we will offer a pro-rata refund or equivalent remedy.

When you grant Momentarily access to your Google or iCloud calendar, you authorise us to access the scopes described in our Privacy Notice. You can revoke access at any time from your Google account, by unsubscribing the ICS URL, or by removing the integration from Momentarily.

8. Subscriptions, fees, and refunds

Tiers and billing

Momentarily offers a Free tier with monthly usage caps, and paid tiers (Pro, Circle, and optionally a Lifetime pass) with higher limits and additional features. Current pricing, features, and caps are shown on the pricing page, which forms part of these Terms.

Paid plans renew automatically at the end of each billing period (monthly or yearly, depending on the cadence you choose) until you cancel. Fees are charged in advance through our payments processor, Stripe. Applicable taxes may be added at checkout; we rely on Stripe Tax to calculate them where enabled.

Trials and promotions

Where we offer a free trial, promo code, or discounted period, the specific terms of that offer will be presented at the point of sign-up (for example, the duration of the trial and the card charge that follows). If you don't cancel before the trial ends, you authorise us to charge the subscription fee to your payment method.

Changes to pricing

We may change subscription pricing from time to time. For active paying accounts, price changes take effect at the start of your next billing period, and we'll notify you by email at least thirty days beforehand. If you don't agree with the new price, cancel before it applies and your subscription will end at the close of the current period.

Refunds and cancellation

You can cancel at any time from the Stripe customer portal (reachable from Settings). Cancellation prevents future renewals and takes effect at the end of your current billing period, during which your paid entitlement remains active.

If you're a consumer in the UK or EEA and you sign up for a paid subscription, you have a statutory right to cancel within fourteen days of purchase. By choosing to access paid features during that period you expressly request immediate performance and acknowledge that you lose your right to a full refund for the portion of the Service you've used; we will refund the unused portion on a pro-rata basis. Outside the cooling-off period we do not generally offer refunds for partial periods, except where required by law or at our sole discretion.

Lifetime passes (where offered) are one-off payments that grant perpetual access to the Service as it existed at the time of purchase, subject to these Terms and our ongoing ability to operate the Service.

Failed payments

If your payment method is declined, Stripe will retry according to its standard dunning schedule. We may downgrade your account to Free tier after a reasonable grace period if the subscription can't be renewed. You're responsible for keeping your payment details up to date.

9. Suspension and termination

By you. You can stop using the Service and delete your account at any time from Settings → Danger zone. Deletion removes your user record and most user-generated content; some data may be retained as described in the Privacy Notice.

By us. We may suspend or terminate your access (and any associated licences) with or without notice if:

  • you materially breach these Terms;
  • we're required to do so by law, court order, or a valid request from a regulator or law-enforcement authority;
  • your account poses a security, legal, or reputational risk to us, our partners, or other users;
  • the Service or a material feature of it is permanently discontinued, in which case we will (where practical) give you at least thirty days' notice.

On termination, your right to use the Service ends immediately. Provisions that by their nature should survive (including sections on Your Content licence, fees owed, disclaimers, limitation of liability, indemnity, and governing law) will survive.

10. Intellectual property

The Service, including its software, visual design, marks, and content we create, is owned by Momentarily or its licensors and is protected by copyright, trade-mark, and other intellectual property laws. Except for the limited licence granted in Section 4, these Terms do not give you any rights in our intellectual property.

If you give us feedback, suggestions, or ideas about the Service (“Feedback”), you grant us a perpetual, irrevocable, royalty-free licence to use, modify, and incorporate that Feedback for any purpose, without attribution or compensation.

11. Privacy and data protection

Our Privacy Noticeexplains what personal data we collect, why we collect it, and the rights you have over it. By using the Service you acknowledge that notice and agree to the processing described in it. Where we act as a data processor on your behalf (for example, processing limited personal data about your guests so you can schedule an event), we do so only on your documented instructions as expressed through the Service's features, and in accordance with applicable data-protection laws.

12. Disclaimers

The Service is provided “as is” and “as available”, without warranties of any kind, whether express, implied, or statutory, to the maximum extent permitted by law. Momentarily does not warrant that the Service will be uninterrupted, timely, secure, error-free, or that scheduling suggestions will always be accurate, complete, or lead to a successful event.

Nothing in these Terms excludes or limits our liability for: (a) death or personal injury caused by our negligence; (b) fraud or fraudulent misrepresentation; or (c) any other liability that cannot be excluded or limited under applicable law. If you deal with us as a consumer, your statutory rights — including those under the UK Consumer Rights Act 2015 — are not affected by these Terms.

13. Limitation of liability

Subject to Section 12, our total aggregate liability to you under or in connection with these Terms, whether in contract, tort (including negligence), breach of statutory duty, or otherwise, is limited to the greater of (a) one hundred pounds sterling (£100) and (b) the total fees you have paid to us for the Service in the twelve months immediately preceding the event giving rise to the liability.

To the extent permitted by law, Momentarily will not be liable for:

  • loss of profits, revenue, or anticipated savings;
  • loss of business, opportunity, goodwill, or reputation;
  • loss or corruption of data or information beyond what our Privacy Notice commits us to maintain;
  • any indirect, special, incidental, consequential, or punitive damages;
  • the acts or omissions of third-party services (Google, Apple, Stripe, Neon, Vercel), or any outages, inaccuracies, or changes attributable to them;
  • missed or failed invitations resulting from email delivery issues outside our reasonable control.

14. Indemnity

If you use the Service in breach of these Terms, of the law, or of the rights of another person, you agree to defend, indemnify, and hold Momentarily and its directors, employees, and partners harmless from any claim, liability, damage, loss, and expense (including reasonable legal fees) arising out of that breach.

15. Changes to these Terms

We may update these Terms from time to time. Where a change is material — for example, a new user obligation, a price change, or a change to refund rights — we will give reasonable notice (typically at least thirty days) by email or through an in-product banner before the change takes effect. Where a change is minor (clarity fixes, updated references) we'll simply update the “last updated” date above.

Your continued use of the Service after the effective date of an updated version means you accept the new Terms. If you don't accept them, you must stop using the Service and, where you're a paying subscriber, you can cancel in line with Section 8.

16. Governing law and disputes

These Terms and any dispute or claim arising out of them (including non-contractual disputes) are governed by the laws of England and Wales. The courts of England and Wales have exclusive jurisdiction to settle any such dispute, except that if you are a consumer resident in another part of the UK or in the EEA, you may also bring proceedings in the courts of your country of residence as required by local law.

Nothing in this section prevents either party from seeking urgent injunctive relief in any jurisdiction where appropriate.

17. General

  • Entire agreement. These Terms, together with the Privacy Notice and any documents they reference, are the entire agreement between you and Momentarily relating to the Service, and supersede any prior agreement on the same subject.
  • Assignment. You may not assign or transfer these Terms or any rights under them without our prior written consent. We may assign these Terms to an affiliate or successor in connection with a corporate transaction, provided your rights are not materially reduced.
  • Severability. If any provision is found unenforceable, the remainder of these Terms will continue in full force.
  • No waiver. A failure to enforce a right is not a waiver of that right.
  • Force majeure. Neither party is liable for a failure to perform caused by events beyond its reasonable control, including network outages, third-party service failures, industrial action, or natural events.
  • Notices. We may send notices to the email address on your account. You should send notices to hello@momentarily.online.
  • No third-party rights. Nothing in these Terms grants any rights to any third party under the Contracts (Rights of Third Parties) Act 1999, except that our affiliates may enforce any provision that benefits them.
