Terms of service

These are the terms for using Sightwick. They are written to be read, not skimmed past. They also contain our data processing terms, so you do not need a separate document. Effective 17 September 2026.

Who we are, and who you are

Sightwick is the trade name of the sole proprietorship (eenmanszaak) of Nick van der Zwart, registered with the Dutch Chamber of Commerce (KvK) under number 88503402, at Amstelhof 77, 2262 EG Leidschendam, the Netherlands. Email: info@sightwick.com. "We" and "us" in these terms means Sightwick.

"You" means the business that uses the service. Sightwick is built for businesses, not for consumers. By using the service you confirm that you act in the course of a business or profession, and that the person accepting these terms may bind that business. You accept these terms when you start a trial, subscribe, or first log in to the dashboard.

What the service is

Sightwick counts conversions on your own website (quote requests, phone clicks, bookings, purchases and similar actions), gives each a value you set, shows which ad or source sent it, and, when you switch sending on, sends those conversions to the destinations you connect. You use it through the dashboard at app.sightwick.com and through one script that you place in the head of your site.

We scan your site to find the actions that count. The scan reads the public pages of the domain you give us and nothing else.

Your account and the trial

A new site starts with a free trial of 14 days on your own domain, without a payment method. The 14 days start on the day the script is in your site. During the trial every screen is switched on and nothing leaves to a destination until you switch sending on.

If you do not subscribe, we switch the trial site off and delete its data within 60 days after the trial ends. If you do subscribe, the site continues without interruption.

Keep your login to yourself. You are responsible for what happens under your account, and for the logins you hand to colleagues or clients through the dashboard.

Plans, prices and payment

The plans and their prices are on the pricing section of sightwick.com. Prices are per month, in euros, excluding VAT. Each plan includes a number of events per month; an event is one page view, signal or conversion your site sends. We count events on our server, and the count in your dashboard is the count that applies.

Events above your plan's allowance are charged at the per-1k rate shown with your plan, in arrears, on the invoice after the month in which they happened. Until we tell you by email that overage billing has started, you are not charged for overage.

You pay the plan monthly in advance through Stripe, our payment provider. You can cancel any month; the subscription ends at the end of the period you already paid for, and we do not refund part of a month. There is no setup fee.

If a payment fails, we tell you and try again. If it keeps failing, we can pause sending to destinations and, after a further notice, close the site. We can change prices with 30 days' notice by email; a change never applies to a period you already paid for.

Your site and your visitors

You may only connect a site you own or are allowed to measure on behalf of its owner. You are responsible for showing your visitors a consent banner where the law requires one, and for what you tell them about measurement. Sightwick reads the visitor's answer from that banner: without consent a visit is counted without an identifier and never reaches a destination.

If you connect a client's site, you warrant that the client has authorised you to engage us as a sub-processor and that you pass the data section of these terms on to the client. Toward us you remain the party responsible for that site, its logins and its payment.

You may not use Sightwick to measure or profile people in ways the law forbids, to collect health, financial or other special categories of data, or to track children. You set the values of your conversions; we count, we do not vouch for the amounts you choose.

Data: we process, you decide

For the data of your visitors you are the controller and we are your processor. This section is our data processing agreement. A signed copy with the same content is available on request.

What we process for you. Subject: measuring conversions on your site and sending them to the destinations you switch on, for as long as you have an account. Data subjects: the visitors of your site. Data: page URLs and referrers, click IDs, a visitor ID (only with the visitor's consent), IP address and browser type, a hashed email address or phone number where your site provides one, and the conversion values you set. We keep events for 25 months so you can compare year on year; the hashes, browser identifiers and the sending log for 90 days.

Instructions. We process only on your documented instructions; the settings in your dashboard are those instructions. If we think an instruction breaks the law, we tell you before we follow it. We do not use your visitor data for our own purposes, and we do not sell it.

Who receives it. We share your visitor data only with the destinations you connect and switch on: Google Ads, Meta and Google Analytics 4. Sending to a destination is your instruction to us. Each platform is a separate controller of what it receives and processes it under its own terms, partly in the United States under the EU-US Data Privacy Framework. Beyond that, only the sub-processors below see your data:

This list was last updated on 17 September 2026. We tell you by email at least 30 days before we add or replace a sub-processor. If you object on reasonable grounds and we cannot resolve it, you may end the contract before the change takes effect.

Security. Everyone who works with your data for us is bound to confidentiality. We protect the data with TLS in transit, hosting in the European Union, access limited to named people, a daily backup, and encryption of the ad platform tokens at rest with a key kept outside the data and its backups, and we keep those measures up to date. We tell you without undue delay if we learn of a breach that affects your data.

Help and checks. If a visitor asks you to see, correct or delete their data, we help you within the time the GDPR gives. We help you with data protection impact assessments and with consultations with the supervisory authority where they concern our processing. Once a year, or after a breach, we answer your written questions and show the evidence you reasonably need to check that we comply; an audit on site is by appointment and at your cost.

At the end. After your subscription ends the dashboard stays readable for 14 days so you can export your data. After that we delete your visitor data within 60 days, except what we must keep by law. How we handle data about you, the customer, is in our privacy statement.

The destinations you connect

You can connect Google Ads, Meta and Google Analytics 4 to Sightwick. By connecting a Google Ads or Meta account you allow us to: see which accounts your login can manage, so you can pick one; read the campaign, ad and spend figures of the account you pick; create or select the conversion actions that Sightwick sends to; and send conversions to that account. We use that access for nothing else. Google asks you for two permissions for this (Google Ads and Data Manager); both are needed.

With your visitor's consent, and only where your site provides them, a conversion carries the click ID, a hashed email address or phone number, the IP address and browser identifiers, because the platform needs them to match the conversion to the click. Without consent nothing is sent.

You can revoke the access at any time: Disconnect in Settings erases the token on our side and revokes it at Google or Meta; you can also revoke it in your Google or Meta account. Either way we stop within a day. Sightwick's use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements. The platforms decide for themselves what they do with the conversions we send; we are not responsible for their decisions or their reports.

Availability

We run the service so that it is available around the clock, but we do not guarantee uninterrupted availability. We can take the service down briefly for maintenance and try to do that at quiet hours. A gap in measurement is not something we can restore, and it does not give a right to a refund, except where the law says otherwise.

What is ours and what is yours

The software, the scan, the dashboard and the script stay ours; you get the right to use them for your sites for as long as you have an account. Your data stays yours. We may use figures that cannot be traced to you or your visitors, such as how many sites run a certain consent banner, to improve the service.

Liability

We are liable only for direct damage caused by a breach of these terms on our side, and only up to the amount you paid us in the 12 months before the damage occurred. Direct damage means the reasonable costs of establishing the cause and extent of the damage, of preventing or limiting it, and of getting the service to do what these terms say. The cap is a total for all claims in any 12 months.

We are not liable for indirect damage, such as lost revenue or lost ad performance, for decisions you or a platform take on the basis of our figures, or for values, settings and consent banners you configured yourself. Nothing in these terms limits liability that cannot be limited by law.

You indemnify us against claims from your visitors, your clients or a supervisory authority that arise from your site, your consent banner, the values and settings you chose, your instructions, or use of the service in breach of these terms.

Ending

You can end your subscription any month, as described above. We can end or suspend your account if you break these terms, if a payment keeps failing, or if your use puts the service or other customers at risk. We tell you why, and where possible first; if your use threatens the security of the service or other customers, we may suspend first and tell you straight after. If we stop offering the service, we give you at least 60 days' notice.

Changes to these terms

We can change these terms. We email you at least 30 days before a change takes effect. If you do not agree, you can end your subscription before that date; using the service after that date means you accept the new terms.

Dutch law

Dutch law applies to these terms. A dispute goes to the competent court in The Hague, the Netherlands, unless the law gives you the right to another court. If part of these terms turns out to be invalid, the rest stays in force.
