Privacy Policy

Effective June 30, 2026 · Last updated June 30, 2026

The short version. Upcheck collects only what it needs to monitor the URLs you choose and notify you when they change. We don't ask for your name, we don't show ads, and we don't use third-party analytics or trackers. You can delete your account — and everything tied to it — from inside the app at any time.

1Who we are

Upcheck ("the app", "we", "us") is a health-check and uptime monitoring app for iPhone, iPad, and Mac, provided by Rekwiem. This policy explains what data the app and its backend handle when you use them. If you have questions, reach us at team@rekwiem.com.

2What we collect

We collect the following, and nothing more:

Data	What it is	Why
Account identifier	If you sign in, we receive a stable, Apple-provided user identifier through Sign in with Apple. This is an opaque ID — not your name, and not your email (Apple lets you hide your email; we never receive it).	To link your monitors and settings to your account across your devices.
Guest account	You can use Upcheck without signing in. We then create an anonymous account tied to your device using Apple's App Attest, and store the attestation public key.	To give you an account without any personal identifier, and to verify requests come from a genuine copy of the app.
Monitor configuration	The names, URLs, and settings (check interval, timeout, "slow" threshold, HTTP method) of the monitors you create.	The URL is what we check; the settings control how and how often.
Check results	For each check: the status (up / slow / down), total latency and its breakdown (connect, time-to-first-byte), the HTTP status code, and a short failure reason (e.g. "timeout", "dns_fail"). Kept as recent events plus hourly aggregates.	To show you uptime, latency trends, and history.
Push token & platform	If you enable notifications, your Apple Push Notification service (APNs) device token and your platform (iOS / iPadOS / macOS).	To deliver alerts when a monitor changes state.

We do not require an account email, phone number, or profile. We don't ask for payment details directly — any subscription is handled by Apple through the App Store, and we never see your card.

3How we use your data

To run the checks you set up and record their results.
To send the notifications you ask for when a monitor's state changes.
To show uptime, latency, and history in the app and its widgets.
To prevent abuse of the service (via App Attest) and keep it running reliably.

We do not use your data for advertising, profiling, or to build a marketing profile. We do not sell or rent it.

4What we don't collect

Upcheck contains no third-party analytics, advertising, or tracking SDKs. We do not collect your name, email, contacts, photos, precise or coarse location, browsing history, or advertising identifiers. We don't track you across other apps or websites.

We don't sell your data or share it for anyone else's marketing. A small number of providers process data strictly to deliver the service:

Apple — for Sign in with Apple, App Attest, and push delivery via APNs. Your use of these is also governed by Apple's Privacy Policy.
Cloudflare — our infrastructure provider. The backend runs on Cloudflare Workers, and your account, monitor, and check data are stored in Cloudflare's database (D1) and key-value store (KV).
The endpoints you choose to monitor — when you add a URL, Upcheck sends HTTP requests to that URL from Cloudflare's network to measure its response. Only add URLs you control or are authorized to check.

We may disclose data if required by law, or to protect the rights, safety, and security of our users and the service.

6Data retention

We keep your account and its data while your account is active. Check results are retained as recent events and as longer-lived hourly aggregates so you can see trends over time. When you delete a monitor, its data is removed. When you delete your account, we erase your account, monitors, check history, aggregates, and device tokens.

Guest (anonymous) accounts that go unused for 30 days are automatically and permanently deleted, since they cannot be recovered. If you delete the app and we can no longer reach any of your devices, we stop running your checks.

7Your choices & rights

Delete a monitor — removes it and its history at any time, from the app.
Delete your account — the app offers in-app account deletion, which permanently erases all data associated with you.
Turn off notifications — disable them in the app or in your device's system settings; we then stop using your push token.

Depending on where you live, you may have rights to access, correct, export, or delete your personal data. Because account deletion already removes everything we hold, the fastest route is in-app deletion — or email us at team@rekwiem.com and we'll help.

8Security

Traffic between the app and our backend is encrypted in transit (HTTPS/TLS). Requests are verified with App Attest to ensure they come from a genuine copy of the app, and sessions use signed tokens. No method of storage or transmission is perfectly secure, but we work to protect your data and limit what we collect in the first place.

9Children

Upcheck is a developer tool and is not directed to children. We do not knowingly collect personal data from children under 13 (or the minimum age required in your country). If you believe a child has provided us data, contact us and we'll delete it.

10Changes to this policy

We may update this policy as the app evolves. We'll revise the "Last updated" date above and, for material changes, surface a notice in the app. Continuing to use Upcheck after an update means you accept the revised policy.
