1. Acceptance of terms
By accessing or using up4 (“Service”), you agree to be bound by these Terms of Service. If you do not agree, do not use the Service.
2. Description of service
up4 provides uptime monitoring, status pages, incident management, and related services. We reserve the right to modify or discontinue features at any time.
3. User accounts
You are responsible for maintaining the confidentiality of your account credentials and for all activity under your account. You must provide accurate information during registration.
4. Acceptable use
You agree not to use the Service for any unlawful purpose, to abuse or overload our infrastructure, or to interfere with other users’ access to the Service. Monitor only endpoints you own or are authorized to monitor.
Target protection. To protect monitored endpoints and other customers, we apply per-target request and concurrency limits. When an endpoint responds with HTTP 429 or 503, checks to that target may be slowed temporarily. Deferred checks are not reported as target failures and only checks that actually run are billed.
Protection limits. To protect the Service and other customers, some features are subject to protection limits. They are set so that they are never reached in normal use. On request we raise a limit for legitimate use at no extra charge. We lower a limit for a Company only in case of abuse or danger to the Service, and we notify you when we do. Included amounts you have booked are never reduced by a protection limit. Status mails to subscribers are bundled under heavy load instead of being dropped.
Status page subscribers. Your plan includes a pool of confirmed e-mail subscribers for all status pages of your Company; the included amount is in the current price list. When the pool is full, we do not accept new sign-ups or imports; existing subscribers are not removed and keep receiving every message. On pay as you go we charge subscribers above the included amount per day according to the price list.
Sending status mail. Status mails are not a promised individual service per recipient. We send the first message of an incident or maintenance and its resolution without delay, as far as the mail route is available. We may combine further updates per subscriber and incident, limit the messages of a page in case of loops and abuse, and mails we could not send within 24 hours expire. The status page itself is always current and authoritative. When the mail provider accepts a mail, that does not mean it reaches the recipient’s inbox; spam filters and delivery errors are outside our control. On request we can raise individual values for a Company.
Agency use. Monitoring assets that belong to your clients as part of your own services — maintenance retainers, white-label reports, client portals and status pages — is expressly permitted; the Agency plan exists for exactly this. The account holder remains our sole contract partner and is responsible for all activity, usage and payment under the account.
One organization per account. An account may only be operated by the single legal entity that holds it. Sharing or sub-renting account access to third parties outside your own organization is not permitted; read-oriented client access through portals, share links and status pages is unaffected.
Platform resale. Offering the Service itself as your own product — for example reselling monitoring capacity or building a competing service on our API — requires a separate written agreement. Talk to us; we are open to partner arrangements.
5. Data and privacy
Your use of the Service is also governed by our privacy policy.
For personal data processed on your instructions, the separately concluded Data Processing Agreement including its annexes forms part of the contract and takes precedence on data-protection matters. The Company owner concludes it in Company settings with the stated authority. Agency processors must have their customer’s authority to appoint up4 as a further processor. No previous acceptance is inferred from visiting this page or from an existing account.
6. Starting credit, billing and balance
Starting credit. New accounts receive a one-time starting credit with full feature access — no payment method is required. The credit is drawn down by usage and by the monthly minimum (see below), so it lasts up to three months of light use. When the starting credit is used up, monitoring is paused; the seven-day grace mode described below applies only after your first payment (a top-up or a subscription). Your account and data remain accessible, and monitoring resumes at your configured intervals as soon as you top up a balance or subscribe to a plan. Data of paused accounts is retained for at least 30 days.
Prepaid balance. You can pay for the Service by topping up a prepaid balance (minimum top-up €10). Every check actually sent — HTTP, Ping, TCP, DNS, keyword or body — every scheduled-job check-in we accept, and every successful incident screenshot is deducted from the balance at the rates published on our pricing page. Alert deliveries, playbooks and seats have no separate usage charge. A published status page has no separate usage charge either, unless it has a business feature switched on (removing up4 branding, password protection, or e-mail-code access), which is billed hourly at the rate on the pricing page for as long as it is published with the feature active. A monthly minimum charge (currently €3) applies to pay-as-you-go accounts: in any calendar month where your usage is below the minimum, the difference is deducted from your balance; months where your usage exceeds the minimum are charged for usage only. Top-ups are single-purpose credits for up4 services; VAT is charged at the time of purchase where applicable. Your balance does not expire before the statutory limitation period (three years from the end of the year of purchase, §195 BGB). For an approved account-deletion request, we review any remaining topped-up balance on request; promotional and starting credits are excluded from refunds.
Subscriptions. Alternatively, you can subscribe to a plan (Team or Agency), billed monthly or yearly, with a large included monthly usage budget for checks and check-ins, a separate monthly allowance of incident screenshots, and all generally available product features. If you reach the checks-and-check-ins budget, existing active monitors keep their current rate, but adding or resuming monitors, adding regions, or tightening intervals is paused until the next monthly reset, a plan upgrade or a booked checks pack. When you create or change a monitor, we project the checks of all active monitors over one month for Team and Agency. If that projection would exceed the included budget, we do not accept a change that causes additional checks (a new or resumed monitor, an additional region, a tighter interval) until you reduce the load (longer interval, fewer regions, pause or delete monitors) or change your plan. Running monitors keep running, and a change that lowers the load is always possible. This check applies only to subscriptions with a fixed budget, not to pay as you go or the starting credit, where you can top up your balance yourself at any time. After a switch to a smaller plan nothing is stopped: existing monitors keep running, and only new or larger load is refused until it fits the budget of the new plan. If you reach the incident-screenshot allowance, no further screenshots are taken until the same reset, an upgrade or a screenshot pack, at no extra charge. The budget and the allowance reset every calendar month on both billing intervals.
Add-ons. On top of a subscription (Team or Agency) you can book packs that raise a limit of your plan in fixed steps: custom domains, email subscribers, incident screenshots, monitors, scheduled jobs and checks. The pack size and price of each kind are shown on the pricing page and in the app at the time of booking; up to 20 packs of each kind can be booked. Packs are billed like your subscription: at the monthly price when you pay monthly, at the yearly price on a yearly subscription. If your subscription changes how it is billed, the packs change with it. Booking more takes effect immediately; we charge the prorated amount for the rest of the current billing period and the full price per period from then on. Booking fewer takes effect at the end of the paid period, on a yearly subscription at the end of the contract year, and can be withdrawn until then; we do not refund anything for the running period. Screenshot and check packs apply to the respective UTC calendar month and, in the month of booking, pro rata; all other packs apply in full immediately. Packs end with the subscription. If you are over a limit, we do not delete anything; further entries of that kind are refused until you are back under the limit or book a pack. If the payment for an add-on is declined, the change stays pending and takes effect only once it is paid; your subscription keeps running. Pay as you go has no packs: there, a custom domain is charged per day from your balance, and everything else by use.
Term and cancellation. Monthly subscriptions renew monthly and can be cancelled to the end of the billing month. A yearly subscription is paid in advance for a term of twelve months and can be cancelled to the end of that term. After the term it continues for an indefinite period at the plan’s monthly price (currently €19 for Team and €49 for Agency, plus VAT where applicable) and can then be cancelled at any time to the end of the billing month. About 30 days before a yearly term ends we remind you by email and you can book another yearly term. Switching from monthly to yearly billing takes effect immediately and starts a new twelve-month term; the unused part of the current month is credited. An upgrade from Team to Agency takes effect immediately and is charged pro rata; a downgrade and a switch from yearly to monthly billing take effect at the end of the current billing period. You cancel in the billing portal, which you reach from the billing settings in the app. Amounts already paid are not refunded pro rata on cancellation; statutory rights, including a right of withdrawal that the merchant of record applies, remain unaffected. You can also declare a cancellation without logging in at Cancel contracts here.
Payment processing & merchant of record. Payments are processed by Stripe. Where a purchase is completed through Stripe Managed Payments, Stripe (operating as “Link”) acts as the merchant of record for that transaction: Link is your seller for the purchase, issues the receipt or invoice, and handles applicable taxes. Your card statement will show LINK.COM* together with our descriptor. The monitoring service itself is provided by us under these Terms.
No lock-in, no dunning. We never delete data because of an empty balance, and we never bill into the negative: after your first payment, monitoring first degrades to five-minute checks for a seven-day grace period, free of charge, and only then pauses. Prices may change for future usage; the rates applicable to your usage are always the ones published at the time the usage occurs.
7. Limitation of liability
The Service is provided “as is” without warranties of any kind. We shall not be liable for any indirect, incidental, or consequential damages arising from your use of the Service.
8. Changes to terms
We may update these Terms from time to time. Continued use of the Service after changes constitutes acceptance of the revised Terms.
