FAQ

Frequently asked questions about Subtraq

Eight groups, 40 questions, one short answer each — and a link to the page that goes deeper when needed. If yours is missing, we want to hear it.

See the demo

The first four, always the same

  1. Does it work without a pixel?Yes. The link does the work, and nothing is placed on your client’s website.
  2. What if you go down?Links keep redirecting: they are served by a separate network.
  3. Is it free?Yes, to start: 2 client workspaces and 10 links per month.
  4. What about GDPR?Hosted in the European Union, and no IP address written to the database.

They come up in this order, every time. The longer answers are below, group by group.

Tracking and attribution

The core of the product: linking a payment to the placement that produced it, without touching anyone’s website.

What counts as a ‘tracked click’?

A visit that came through a Subtraq link, bots excluded. A single link can be clicked a hundred times: those are a hundred counted clicks. The source of a sale, though, stays as the person’s first known click — once set, nothing moves it. The industry glossary

How do you know which link made the sale?

Every link carries a hidden identifier, stored for thirty days in the visitor's browser. When they buy, that identifier comes back with the sale, and the report knows which door they came through. From click to payment

Do I need to place a pixel or a script on my site?

Not to count clicks: open a workspace, create a link, share it, and counting starts immediately. A small snippet only comes in later, to tie an identified prospect in your system. A pixel, on the other hand, lives in a page: it dies on a redesign, a refused consent, or an ad blocker. Measuring without a pixel

What is the difference between attribution and tracking?

Tracking records what happened: a click, a visit, a purchase. Attribution decides who gets the credit. You can track everything and attribute nothing: numbers everywhere, and no answer. Attribution models

What happens if no click matches a sale?

It is recorded as unattributed and shows up as such in the report. The engine never fabricates a plausible source: an incomplete report is less dangerous than a report that invents. What the client sees

Marketing attribution, developed as a pillar page

Links and domains

A short link is only valuable if it belongs to you. It is the domain that decides whether it survives when you switch tools.

Can I use my own domain name?

Yes. A subdomain of your existing domain, such as link.youragency.com, works perfectly and costs nothing extra. A dedicated very-short domain is a convenience, not a requirement. Choosing a domain

If I switch tools, what happens to my links?

That is the whole point of the domain: it is yours. You take it with you, and your links go with you. This is the opposite of a free shortener, where the address belongs to the tool and dies with the subscription. Leaving a shortener

What happens to my links if Subtraq goes down?

They keep redirecting. Links are distributed by a separate edge network that holds its own copy: redirection consults neither the application nor the database. The infrastructure

Can a link expire, or disappear?

Not on its own. A link lives as long as you do not archive it, and even after downgrading a plan, existing links keep redirecting. A link is never deleted from the database: it is archived so its history stays readable. The life of a link

Can I bring over links from another tool?

Your destinations, yes, by CSV export then import here. The short addresses from the old tool, no: they belong to it. And the counters start from zero on the day you switch. Bulk import

Why the domain decides everything

Integrations

The principle never changes: a Subtraq link in front, your tool behind it, and the sale confirmation coming back. What changes is the path through each interface.

Which tools does Subtraq connect to?

Tally, Typeform, Calendly, Cal.com, Systeme.io, Brevo, Elementor, Stripe, Zapier, and Make. For each one, the steps were recorded in the real interface, with the date of the recording — not a "coming soon" logo. The ten guides

What if my tool isn’t in the list?

Zapier or Make act as the bridge: they expect an address and a JSON payload, which is exactly what Subtraq sends. Nothing to install on their end, nothing to publish. It is two extra clicks, not a project. The Zapier bridge

Do I need a developer to set this up?

Not for the common cases. A short link per placement is created in a few seconds, and the most common tools connect through their own interface, without writing any code. A developer becomes useful for a custom website or application. A three-step connection

How does a Stripe sale come back?

Through a webhook on a single event type, checkout.session.completed, and a secret pasted into Subtraq. Since the same payment can arrive under two different event types, deduplication is done on the payment identifier. The Stripe guide

Does my client need to give me access to their site?

No, and that is often what unblocks the situation: there is nothing to place on their site. You create the link here, you connect the sales tool, and the client’s website is never touched. The agency use case

The integration hub, tool by tool

Reports and client workspaces

One workspace per client, genuinely walled off, and a report that leads with the number the client is looking for.

What exactly is a client workspace?

A watertight data partition per client: every link, every click, every sale belongs to one workspace and one only. This is different from a simple filter, which is just a view laid over mixed data. The partitioning

Can my client log in themselves?

Yes, with read-only access to their workspace alone. They see neither your other clients, nor your costs, nor your internal notes — they see their links and what they brought in. Alternatively, a report page can be shared with a plain link. Access levels

Can the report carry my brand instead of yours?

Yes, from the paid plan: the right to remove the "Powered by Subtraq" mention is included. On the free tier, the mention stays — it is our only acquisition channel, and we prefer to own that rather than hide it. White labeling

What happens when I lose a client?

The workspace closes, the data stays readable for you, and the client loses access. Nothing is deleted unless you ask for it. Opening and closing a workspace

Am I notified if a link breaks?

Yes: a link whose destination stops responding, an unusual click spike, and a sharp drop each trigger an alert. The worst time to find out a link is dead is when the client tells you. The three alerts

How workspaces are kept separate

Pricing and the free version

Four counters, each answering a specific objection. Prices are in dollars and don’t change.

What exactly is the free tier limited to?

2 client workspaces, 10 links per month, 3,000 clicks counted, and 1 custom domain. Enough to run links for a real client and see whether the question "how much did it bring in" gets an answer. What the free tier allows

What does the paid plan include?

$39 a month, or $390 a year — two months free. It gives 15 client workspaces, 1,000 links per month, 100,000 clicks counted, 15 domains, and white-label reporting. Above that, the $99 plan lifts the caps on workspaces, links, and domains. All the plans

What happens if I exceed the counted clicks?

Redirection continues — your links never break. Only counting stops until the following month. We do not hold your links hostage. Going over the limit

When can I cancel?

Any time, from the subscription page. You keep the paid plan until the end of the period, then drop back to free — your data stays, and your existing links keep redirecting. Changing plans

Why dollars and not euros?

Payment goes through Stripe in US dollars; conversion to your currency is handled by your bank at its exchange rate. Showing a euro price that would shift with every payment would be less honest than a dollar price that doesn’t move. Payment details

Data, GDPR, and security

Most measurement tools have a GDPR problem because they measure people. A short link measures a campaign.

Where is the data hosted?

At Hetzner, in the European Union. There is no American CDN in front of the database, no replication of personal data outside the EU (only link destinations are copied to Cloudflare's network for redirection), and no third-party analytics tool connected to it. The infrastructure

Do you store IP addresses?

Never in the database. The IP address is read in memory long enough to determine the country and filter out bots, then discarded. No device fingerprint either: fingerprinting is forbidden by the product’s design, not merely discouraged. The policy, word for word

Do we need a checkbox in our cookie banner?

The link itself sets no third-party cookie. The optional snippet writes a click identifier in first-party storage on your client’s domain, to be mentioned in their privacy policy. That is your responsibility as publisher. Measuring without a banner

How long does the data live?

Raw events: thirteen months. Statistical aggregates — daily, country, device totals — indefinitely, because they no longer contain personal data. Retention periods

Who is responsible for what under GDPR?

For the clicks and sales from your campaigns, your agency is the data controller and Subtraq acts as data processor under Article 28, on your instructions. A Data Processing Agreement is available on request. Who is responsible for what

What happens if we leave?

Your data exports to CSV, the workspace is deleted on request, and the deletion is real — not a “deactivated account” that keeps everything. Backups are daily, retained for fourteen days, and their restore has been tested, not just configured. Export and deletion

API, webhooks, and agents

The MCP server and the API share the same tool registry. What one exposes, the other exposes — never one without the other.

Is there an API?

Yes, a v1 API documented in OpenAPI: the full contract is available at /api/v1/openapi.json, generated from the same registry as the MCP server. Eight tools, one API key, no SDK to install. The API and its eight tools

What is the MCP server, and which agents does it work with?

An endpoint that any MCP client knows how to call: Claude, in both the desktop app and the command line, and other compatible clients. The server speaks the standard protocol — initialize, tools/list, tools/call — with no proprietary extension. Subtraq and AI agents

Can an agent break something?

It does exactly what its API key permits, within that key’s workspace. No mass deletion exposed: the tools create, read, and update. Every call is logged like any normal API call. What an agent can do

Can I receive a webhook for each conversion?

Yes: a JSON payload sent to the address of your choice, signed by an x-subtraq-signature header that lets you verify the sender. If your endpoint is unavailable, the conversion is recorded anyway: it is the delivery that fails, two retries then a logged failure. Webhooks

Which plan includes the API and MCP?

They are tied to your workspace API key, and key creation is available in the product. Your plan's limits apply to links created, regardless of where they come from — interface, API, or agent. Quotas

Account and team

What it takes to get started, who sees what, and the tools Subtraq works alongside instead of replacing.

Do I need to install anything to get started?

No. Open a workspace, create a link, share it: clicks are counted immediately. The small snippet only comes later, when you want to tie identified prospects in your system. See it before signing up

Can multiple people work together, and can my client have their own access?

Yes to both, and they are two different things. An agency has an owner, administrators, and members who work across all its workspaces; each invitation has a status: pending, accepted, or revoked. Client access, on the other hand, is read-only on a single workspace — they do not even know the others exist. The two kinds of access

Does Subtraq replace Google Analytics?

No, and the two work well together: analytics looks at the site, links look at the campaigns. The UTM parameters your links carry are in fact read by analytics — they are two different floors of the same building. The two floors of measurement

Does Subtraq replace Linktree, Bitly, or a shortener?

Linktree builds a link page, a shortener builds a short address; Subtraq builds the link and measures what it brings in. If your bio needs just one destination, one link is enough. If it needs several, keep your page and put our links behind its buttons. The three levels of tools
