Terms of service

By using Stelafy you agree to the terms below.

What the service does

The service reads your ad spend from the ad platform, takes the applications and outcomes you bring in, and reports which ads led to applications, qualified leads, won opportunities and money actually collected.

The result is a measurement estimate. It is not an accounting record, an invoice or a tax document, and it is not a substitute for your own books.

The service does not promise a result. No increase in revenue, leads or return on ad spend is guaranteed, and a report is not financial, legal or marketing advice.

Records that cannot be matched are not folded into the ad numbers. They are counted and shown separately, with the reason. The service does not assign a payment of unknown origin to a campaign.

A payment is matched to a person by phone number, email address or lead id — never by name. When that person has more than one lead, the payment goes to their latest lead before the payment, and later installments follow the first payment. A payment dated before all of the person's leads is not assigned; it is shown for review.

What the service does not do

  • It does not create, pause or change ads, ad sets, campaigns or budgets.
  • It does not build custom or lookalike audiences and does not upload customer lists.
  • It does not process health data, and it does not send anything at all for a clinic workspace.

Accounts

  • You must be at least 18 and able to bind the business you sign up for.
  • Give accurate information and keep it up to date.
  • Each person uses their own login. Sharing a login is not allowed; invite the person instead.
  • Keep your credentials safe and tell us straight away if you suspect someone else has used your account.

Your responsibilities

  • Having a lawful basis for the lead, customer and payment data you bring into the service.
  • Having a lawful basis, and the necessary notices and consent, for any outcome event you choose to send to an ad platform — you declare this before sending can be turned on.
  • Connecting only ad accounts and datasets that belong to you or that you are authorised to act for.
  • Keeping account access to the people you actually want to have it, and using the analyst role for people who should only read.
  • Not asking for health, payment card, identity-number or other special-category data in the lead forms you connect. The service drops answers to questions that look like such data before storing anything, but that check is a safety net, not a guarantee: if your form collects such data, you remain responsible for it.

Acceptable use

You must not use the service to:

  • do anything unlawful or fraudulent;
  • reach another workspace, another account or our systems without permission;
  • interfere with the service, including by overloading it or probing it for weaknesses without our written agreement;
  • copy, resell or reverse engineer the service;
  • send spam, or collect contact details from people who did not agree to it.

Sending outcomes to an ad platform

Sending is off by default and can only be turned on by an owner or admin of an eligible general lead-generation workspace. It is permanently unavailable for clinic workspaces.

You choose which events may be sent. The service will not send an event whose real time is unknown or outside the platform's accepted window, and it will not substitute the upload time or an invented identity for missing information — such an event is blocked and the reason is shown.

Acceptance by the platform means the request was received. It does not mean attribution happened or that performance improved, and the service will not present it that way.

To protect your business, Page and ad accounts on the platform, we may pause sending for a workspace if health or other special-category data appears in its connected forms or files, and resume once it is resolved. Meta may restrict an account that sends such data.

Ad platform rules

Building audiences from health data, deriving lookalikes from it, or sending health-related conversion events is against platform rules. The service does not do these things and will not do them on request. Sending for clinic workspaces is blocked in the server, not merely hidden in the interface.

Fees

Scope, fees and term are agreed in writing between the parties. There is no public price list and no self-service subscription.

Confidentiality

Each party keeps the other's non-public business information confidential, uses it only for this agreement, and discloses it only where the law requires — with prompt notice to the other party where that is lawful. This does not cover information that is public, already known, independently developed or lawfully received from someone else.

Suspension

We may suspend access to the service, in whole or in part, if your use breaches these terms or the law, puts the security of the service or other customers at risk, or if a court or authority requires it. We tell you the reason in writing and, where possible, give you a chance to put it right first.

Limits of liability

The service processes the data it is given. It is not responsible for conclusions drawn from gaps or errors in your source data. Where a figure cannot be computed the service says why instead of showing a zero, and unmatched records are shown separately, so that such gaps are visible before you act on a report.

Nothing in these terms limits liability that the law does not allow to be limited, such as liability for death or personal injury caused by negligence, or for fraud.

Neither party is liable for indirect or consequential loss, or for loss of profit, revenue, business or goodwill.

Otherwise, each party's total liability arising from this agreement is limited to the fees paid or payable for the service in the 12 months before the event that gave rise to the claim. This limit does not apply to your obligation to pay fees, to a breach of confidentiality, or to your indemnity below.

Indemnity

You will cover our losses, including fines and reasonable legal costs, from any third-party claim that arises from data you brought into the service without a lawful basis, from data you were not allowed to collect (such as health data in a connected form), or from your breach of these terms.

Availability and changes

The service is provided as it is, without a guaranteed uptime commitment unless one is agreed in writing. If a change materially affects what data is processed or what leaves the product, the privacy policy is updated in the same release.

We may update these terms. For a material change we tell you by email at least 30 days before it takes effect. A change to fees applies only once you agree to it in writing.

Termination

Either party may end the agreement with written notice. After termination your data is deleted within the period stated in the privacy policy, and any pending outcome events are discarded rather than sent.

Governing law

These terms, and any dispute arising from them, are governed by the law of England and Wales. The courts of England and Wales have exclusive jurisdiction.

General

  • These terms, the data processing terms, the privacy policy and any written order form are the whole agreement. A written order form prevails over these terms where they conflict; for personal data processed on your behalf, the data processing terms prevail.
  • Neither party is liable for a delay or failure caused by events beyond its reasonable control. This does not excuse payment.
  • If a provision is found unenforceable, the rest stays in force.
  • Neither party may transfer this agreement without the other's written consent, except as part of a merger or the sale of its business.
  • Notices are given by email to the addresses the parties use for the account.
  • These terms are written in English; any translation is for convenience only.
