pegelWERK is a privacy-friendly service. We collect and process personal data only to the extent technically necessary for providing the service.
All audio processing in the browser tools, including loudness normalisation, spectral analysis, encoding, editing and mixing, is performed entirely locally in the user's browser (Web Audio API, OfflineAudioContext). Audio data never leaves the device. No audio files are stored on or transmitted to servers.
The native pegelWERK apps for iPad, iPhone, macOS and Windows process audio exclusively on the local device. No audio data, measurement results or personal data is transmitted to servers or permanently stored.
Depending on functionality, the apps require the following system permissions:
The apps contain no analytics, no crash-tracking SDK, no advertising libraries and no third-party network communication. Internet access is not required for operation.
pegelWERK-BM is distributed through the Apple App Store (for iPad, iPhone, Mac). When purchasing, installing, updating or accepting optional TestFlight invitations, Apple processes data independently (Apple ID, purchase history, device tokens). We have no control over this. Apple's privacy policy applies: apple.com/legal/privacy.
Apple provides us with aggregated, anonymised sales and crash statistics. These contain no information traceable to individual users.
Sales of the desktop apps (macOS and Windows versions outside the App Store) are processed by our payment provider Paddle (Paddle.com Market Ltd., Judd House, 18-29 Mora Street, London EC1V 8BT, United Kingdom), acting as "Merchant of Record". Paddle processes name, email, billing address and payment details for processing the purchase and issuing a correct invoice including VAT.
Paddle.js is loaded on this website only when the visitor actively clicks the "Buy" button, no connection to Paddle servers is established before that.
Legal basis: Art. 6 (1) (b) GDPR (contract performance). Paddle's privacy policy applies: paddle.com/legal/privacy.
From Paddle, we only receive the buyer's email address for delivery of the licence key and for support purposes. Retention period: for the statutory retention period for invoices (10 years) or until withdrawal for support contact.
The licence email after a successful purchase is sent via the email service provider Resend (Resend Inc., 2261 Market Street #5039, San Francisco, CA 94114, USA). Resend processes only the buyer's email address and the message content (licence key + activation link) for one-time delivery. A data processing agreement under Art. 28 GDPR is in place; EU standard contractual clauses are filed. Resend privacy policy: resend.com/legal/privacy-policy.
This website is served via Cloudflare Pages (Cloudflare, Inc., 101 Townsend St., San Francisco, CA 94107, USA). When pages are requested, Cloudflare automatically records access data in log files. These typically include:
This data is used solely to ensure operation, for error analysis and to protect against attacks (DDoS, bot filtering). Retention follows Cloudflare's default settings for Pages logs. Legal basis: Art. 6 (1) (f) GDPR (legitimate interest). For the data processing agreement with Cloudflare and the EU standard contractual clauses on file, see §10. DNS management for the domain pegelwerk.com is handled by IONOS SE, Elgendorfer Str. 57, 56410 Montabaur, Germany, pure name resolution does not produce additional logs.
This website uses no cookies. No tracking technologies, analytics services (such as Google Analytics), advertising networks or social-media plug-ins are deployed. No user profiles are created.
This website loads all used fonts (Inter, Arimo) exclusively from our own web server. No connection to external font CDNs (e.g. Google Fonts) is established. The visitor's IP address is at no point transmitted to third parties for font loading.
This website and several backend services run entirely on Cloudflare infrastructure (Cloudflare, Inc., 101 Townsend St., San Francisco, CA 94107, USA):
download.pegelwerk.com. When you click the trial-download button, your IP address is transmitted to R2; no additional collection, the download is anonymous, without account or email entry.satk-license-worker.weathered-lake-eea9.workers.dev. Worker invocations process request data (IP, headers, body) ephemerally to answer the request; Cloudflare logs invocations short-term for error analysis by default.A data processing agreement under Art. 28 GDPR is in place with Cloudflare; EU standard contractual clauses are filed. Legal basis: Art. 6 (1) (f) GDPR (legitimate interest in a stable, secure web presence and efficient backend processing) and Art. 6 (1) (b) GDPR (contract performance for licence activation).

This website uses local browser storage (localStorage) exclusively to remember your selected language (key satk-lang, values de or en). The entry is stored only on your device, never transmitted to a server, and serves only to load the same language on your next visit.
Legal basis: § 25 (2) no. 2 TTDSG (technically necessary to provide the function explicitly requested by the user), no consent is required. You can delete the entry at any time via your browser settings (data storage / local data).
This website uses Plausible Analytics (Plausible Insights OÜ, Västriku tn 2, 50403 Tartu, Estonia) for anonymous audience measurement. Plausible records aggregated, non-personal statistics about the use of this website (e.g. number of visitors per page, time on page, geographic region at country level, referring websites).
Plausible sets no cookies, stores no IP addresses persistently (only a hashed daily identifier for return-visit detection, which is renewed every day) and uses no cross-site tracking. No profiling occurs, and the data is not shared with third parties. Processing takes place entirely on EU servers in Germany.
Legal basis: Art. 6 (1) (f) GDPR (legitimate interest in statistical analysis of website usage to optimise the service). Because Plausible operates without cookies and without personal identifiers, no consent under § 25 TTDSG is required.

On the page pegelwerk.com/videos we embed videos from YouTube (Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland). We use a click-to-load solution (two-click principle): when the page loads, only a preview image stored locally on our own server is shown. At this point there is no connection to YouTube or Google, no cookies are set and no data is transmitted to Google.
Only when you actively click a video is the YouTube player loaded in privacy-enhanced mode (domain youtube-nocookie.com). From that point on, YouTube/Google processes data (including your IP address as well as device and browser information) and may set cookies; we have no influence over this. This may involve a transfer to third countries (USA).
The legal basis for loading after the click is your consent (Art. 6 (1) (a) GDPR, § 25 (1) TTDSG), which you give by clicking the respective video. No third party is contacted before the click. Google/YouTube privacy policy: policies.google.com/privacy
The page pegelwerk.com/support provides a contact form for support requests. The data you enter is processed:
Data flow: The form sends the data to a Cloudflare Worker (see §10). The Worker validates the input, checks for spam and forwards the request to our email service Resend (see §6 for provider details and data processing agreement). Resend delivers the request as an email to [email protected]; an automatic confirmation goes to your sender address in parallel.
Rate limiting: To prevent abuse, the Worker stores a SHA-256 hash of your IP address together with a timestamp in a Cloudflare D1 database (see §10). The plaintext IP is not stored. The original IP cannot be derived from the hash. Hash entries are not actively deleted but are functionally irrelevant after > 1 hour and contain no personal data in the strict sense.
Retention: The delivered email in the [email protected] mailbox is retained as long as needed to answer your request and meet any statutory retention obligations. We will delete the email thread on request, informal request is sufficient.
Legal basis: Art. 6 (1) (b) GDPR (pre-contractual / contract performance for licence- or order-related requests) or Art. 6 (1) (f) GDPR (legitimate interest in providing organised support).
Under the GDPR, you have the following rights:
Outside of the processing operations described above (licence purchase, support request), pegelWERK does not collect personal data. For questions or to exercise your rights, contact: [email protected]
