Free uptime monitoring in Europe: what you get, and where your data lives

"Free uptime monitoring" means five different things: how many monitors, how often they run, from where, who may use the plan commercially, and which alert channels come with it. If you work in the EU there is a sixth: where does the monitoring data live, and who else touches it?

This guide covers those six. It is not a ranking. For a ranked list of tools, read best free uptime monitoring tools. Here we explain what to read on a free plan, and what a European team should check about data before it points a tool at a production site. We make Uptrack, so we describe our own setup with its limits.

What "free" really includes in 2026

Free plans differ more in what they limit than in what they offer. The numbers below come from each vendor's public pricing page, checked on October 12, 2026.

We left out the location of the other tools because their pricing pages do not say, and we do not guess. Read their docs. Three more limits hide below the headline numbers:

• Commercial use. Free plans have changed their terms before. Reports about UptimeRobot's free plan differ: some say it was limited to personal use from late 2024, newer ones say the 2026 terms allow commercial use. Read the current terms page of any tool you use for a business site. Ours allows commercial use.
• Alert channels. Email is almost always free. Chat, SMS and phone are where plans differ. Ours has email plus one chat channel (Discord, Slack or Telegram). Webhook, SMS and phone alerts are on Pro.
• Activity rules. Some services pause idle free accounts. Ours can pause free monitors after 37 days without a sign-in, and the number of free accounts is capped, so sign-ups can show "Free plan is full".

Why a monitoring tool touches personal data at all

A monitor stores a URL, a status code, a response time and an error message. That sounds harmless. Three things make it less so. The account holds an email address and a name. Alert recipients are people. And a URL can contain personal data: a path such as /users/anna.meier/export, a query with an order number, a token in a header.

If a vendor stores these for you, GDPR describes the vendor as a processor and you as the controller. Article 28 then expects a written contract with the subject matter, duration, purpose, types of data and your instructions, and it limits the processor from engaging another processor without your authorisation. The text is on gdpr-info.eu, and the European Data Protection Board explains the roles in its guidelines 07/2020. This is general information, not legal advice. Your data protection officer has the final word.

The simplest protection costs nothing: keep personal data out of monitored URLs and headers, and use a dedicated test account.

Where Uptrack stores your data

Our privacy page says it in these words: all data is stored in PostgreSQL databases on Netcup servers in Nuremberg, Germany. We do not use US-based database providers, and backups are encrypted and stored on a separate server. The free plan checks from one location, Nuremberg, so check traffic stays there too.

The same page lists what else touches data, and it is short:

• Paddle takes payments. It handles card data directly, and we never see it. A free account has no payment at all.
• Cloudflare serves the public website as a CDN with DDoS protection, so ordinary web traffic data such as the IP address and headers passes through it.
• Alert and password emails come from our own mail server, not from a third-party email provider.
• We do not use Google Analytics or ad-tracking pixels, and the only cookie is the session cookie.

Retention depends on the plan. A free account shows 30 days of history. When you delete an account, it is deactivated at once and can be restored for 30 days. After that we delete your account, monitors, incidents and check results, and encrypted backups expire within 35 more days.

Two honest limits. First, a Cloudflare layer in front of a website means that not every request path stays inside the EU. Read the privacy page and judge it for your case. Second, this site has no data processing agreement page today. If your company needs a signed one, ask before you rely on the free plan, using the contact address on the privacy page.

The Uptrack free plan, exactly

• 5 monitors, checked every 30 seconds from one location (Nuremberg).
• HTTP and keyword monitors. Ping, port, DNS, SSL, heartbeat and browser checks are on paid plans.
• Email plus 1 chat channel, 1 status page, 1 team member, 30 days of history. Commercial use is allowed.
• The free plan needs a work email address. Paid plans accept any email address. Sign-up takes any address. Signed up with another address? Add a work email address in Settings.

There is no trial, and no credit card is needed for the free plan. The 30-day money-back guarantee covers paid plans.

A checklist for choosing a free plan in the EU

1. The data location is written on a public page, with the country, and you can read it before you sign up.
2. The vendor lists its processors: payment, CDN, email, hosting. Each one says what data it sees.
3. A transfer outside the EEA has a named mechanism, such as an adequacy decision or standard contractual clauses.
4. A data processing agreement is available, and you know whether the free plan gets it.
5. Deletion has a schedule: when your account is removed, when the backups go.
6. The alert text that leaves for Slack, Discord or Telegram holds no personal data, because those messages sit with the chat provider.
7. Your monitored URLs, headers and test accounts hold no personal data about real people.

If a vendor fails the first two, stop there. If it passes all seven, you still have to read the current terms, because plans change.

When Uptrack's free plan is not for you

• You need many free monitors. UptimeRobot lists 50 and HetrixTools 15. Ours has 5.
• You need checks from several locations for free. Free checks run from Nuremberg only.
• You need a signed data processing agreement before the first monitor. Talk to us first, or choose a vendor that publishes one.
• You need SMS or phone alerts without paying. They are on Pro.
• You can only sign up with an address on a free mail provider. The free plan needs a work email address. Paid plans accept any email address.
