Privacy Policy

1. Privacy at a Glance

General Information

The following information provides a simple overview of what happens to your personal data when you visit this website. Personal data is any data that can be used to personally identify you. Detailed information on the subject of data protection can be found in our privacy policy listed below this text.

Data Collection on This Website

Who is responsible for data collection on this website?

Data processing on this website is carried out by the website operator. You can find their contact details in the "Information about the responsible party" section of this privacy policy.

How do we collect your data?

Your data is collected firstly by you providing it to us. This could be data that you enter into a contact form, for example. Other data is collected automatically or after your consent when you visit the website through our IT systems. This is primarily technical data (e.g., internet browser, operating system, or time of page access). This data is collected automatically as soon as you enter this website.

What do we use your data for?

Part of the data is collected to ensure error-free provision of the website. Other data may be used to analyze your user behavior.

What rights do you have regarding your data?

You have the right at any time to receive information free of charge about the origin, recipient, and purpose of your stored personal data. You also have the right to request the correction or deletion of this data. If you have given consent for data processing, you can revoke this consent at any time for the future. You also have the right to request the restriction of the processing of your personal data under certain circumstances. Furthermore, you have the right to lodge a complaint with the competent supervisory authority.

2. Hosting

This website is hosted by an external service provider (host). The personal data collected on this website is stored on the host's servers. This may include IP addresses, contact requests, meta and communication data, contract data, contact details, names, website accesses, and other data generated via a website.

The use of the host is for the purpose of contract fulfillment towards our potential and existing customers (Art. 6 para. 1 lit. b GDPR) and in the interest of secure, fast, and efficient provision of our online services by a professional provider (Art. 6 para. 1 lit. f GDPR).

Our host will only process your data to the extent necessary to fulfill its performance obligations and will follow our instructions regarding this data.

We use the following host:

Vercel Inc.
440 N Barranca Ave #4133
Covina, CA 91723
USA

We use Vercel’s global edge/CDN network for delivery. Transit or processing of data outside the EU may technically occur. Use is based on appropriate safeguards (e.g., EU Standard Contractual Clauses/DPF) by the provider.

3. General Information and Mandatory Information

Data Protection

The operators of these pages take the protection of your personal data very seriously. We treat your personal data confidentially and in accordance with the statutory data protection regulations and this privacy policy.

Information about the Responsible Party

The responsible party for data processing on this website is:

Percol GmbH i.G.
Zum Seeblick 32
45721 Haltern am See
Germany

Phone: +49 1520 338 1723
Email: info@percol.de

The responsible party is the natural or legal person who alone or jointly with others decides on the purposes and means of processing personal data (e.g., names, email addresses, etc.).

Storage Duration

Unless a more specific storage period has been specified within this privacy policy, your personal data will remain with us until the purpose for data processing no longer applies. If you assert a legitimate request for deletion or revoke your consent to data processing, your data will be deleted unless we have other legally permissible reasons for storing your personal data (e.g., tax or commercial law retention periods); in the latter case, deletion will take place after these reasons cease to apply.

Legally Required Data Protection Officer

We have appointed a data protection officer for our company when legally required. You can reach the data protection officer at our email address with the addition "Attn: Data Protection Officer" or at our postal address with the corresponding addition.

Note on Data Transfer to the USA and Other Third Countries

We use tools from companies based in the USA or other third countries that are not secure under data protection law. When these tools are active, your personal data may be transferred to these third countries and processed there. We would like to point out that no level of data protection comparable to that in the EU can be guaranteed in these countries. For example, US companies are obliged to hand over personal data to security authorities without you as the data subject being able to take legal action against this. It therefore cannot be ruled out that US authorities (e.g., intelligence services) may process, evaluate, and permanently store your data on US servers for monitoring purposes. We have no influence on these processing activities.

Revocation of Your Consent to Data Processing

Many data processing operations are only possible with your express consent. You can revoke consent you have already given at any time. The legality of the data processing carried out until the revocation remains unaffected by the revocation.

Right to Object to Data Collection in Special Cases and to Direct Advertising (Art. 21 GDPR)

IF DATA PROCESSING IS BASED ON ART. 6 PARA. 1 LIT. E OR F GDPR, YOU HAVE THE RIGHT AT ANY TIME TO OBJECT TO THE PROCESSING OF YOUR PERSONAL DATA FOR REASONS ARISING FROM YOUR PARTICULAR SITUATION; THIS ALSO APPLIES TO PROFILING BASED ON THESE PROVISIONS. THE RESPECTIVE LEGAL BASIS ON WHICH PROCESSING IS BASED CAN BE FOUND IN THIS PRIVACY POLICY. IF YOU OBJECT, WE WILL NO LONGER PROCESS YOUR AFFECTED PERSONAL DATA UNLESS WE CAN DEMONSTRATE COMPELLING LEGITIMATE GROUNDS FOR THE PROCESSING THAT OVERRIDE YOUR INTERESTS, RIGHTS AND FREEDOMS, OR THE PROCESSING SERVES TO ASSERT, EXERCISE OR DEFEND LEGAL CLAIMS (OBJECTION PURSUANT TO ART. 21 PARA. 1 GDPR).

Right to Lodge a Complaint with the Competent Supervisory Authority

In the event of violations of the GDPR, data subjects have the right to lodge a complaint with a supervisory authority, in particular in the member state of their habitual residence, their place of work, or the place of the alleged violation. The right to lodge a complaint exists without prejudice to other administrative or judicial remedies.

Right to Data Portability

You have the right to have data that we process automatically on the basis of your consent or in fulfillment of a contract handed over to you or to a third party in a common, machine-readable format. If you request the direct transfer of data to another responsible party, this will only be done to the extent that it is technically feasible.

Information, Correction, and Deletion

Within the framework of the applicable legal provisions, you have the right at any time to free information about your stored personal data, its origin and recipients, and the purpose of data processing and, if applicable, a right to correction or deletion of this data. You can contact us at any time if you have further questions on the subject of personal data.

Right to Restriction of Processing

You have the right to request the restriction of the processing of your personal data. You can contact us at any time for this purpose. The right to restriction of processing exists in the following cases:

  • If you dispute the accuracy of your personal data stored with us, we usually need time to verify this. For the duration of the review, you have the right to request the restriction of the processing of your personal data.
  • If the processing of your personal data was/is unlawful, you can request the restriction of data processing instead of deletion.
  • If we no longer need your personal data, but you need it to exercise, defend, or assert legal claims, you have the right to request the restriction of the processing of your personal data instead of deletion.
  • If you have lodged an objection pursuant to Art. 21 para. 1 GDPR, a balance must be struck between your interests and ours. As long as it has not yet been determined whose interests prevail, you have the right to request the restriction of the processing of your personal data.

SSL or TLS Encryption

This site uses SSL or TLS encryption for security reasons and to protect the transmission of confidential content, such as orders or inquiries that you send to us as the site operator. You can recognize an encrypted connection by the fact that the address line of the browser changes from "http://" to "https://" and by the lock symbol in your browser line. If SSL or TLS encryption is activated, the data you transmit to us cannot be read by third parties.

4. Data Collection on This Website

Cookies

Our website uses so-called "cookies". Cookies are small data packets and do not cause any damage to your device. They are stored either temporarily for the duration of a session (session cookies) or permanently (permanent cookies) on your device. Session cookies are automatically deleted after your visit ends. Permanent cookies remain stored on your device until you delete them yourself or until they are automatically deleted by your web browser.

Cookies can come from us (first-party cookies) or from third-party companies (so-called third-party cookies). Third-party cookies enable the integration of certain services from third-party companies within websites (e.g., cookies for processing payment services).

Cookies have various functions. Numerous cookies are technically necessary because certain website functions would not work without them (e.g., the shopping cart function or the display of videos). Other cookies can be used to evaluate user behavior or for advertising purposes. We do not use marketing or advertising cookies.

Cookies that are necessary to carry out the electronic communication process, to provide certain functions you have requested (e.g., for the shopping cart function), or to optimize the website (e.g., cookies for measuring web audiences) (necessary cookies) are stored on the basis of Art. 6 para. 1 lit. f GDPR, unless another legal basis is specified. The website operator has a legitimate interest in storing necessary cookies for the technically error-free and optimized provision of its services. If consent for the storage of cookies and comparable recognition technologies has been requested, processing is carried out exclusively on the basis of this consent (Art. 6 para. 1 lit. a GDPR and § 25 para. 1 TTDSG); consent can be revoked at any time.

You can set your browser so that you are informed about the setting of cookies and only allow cookies in individual cases, exclude the acceptance of cookies for certain cases or in general, and activate the automatic deletion of cookies when closing the browser. If cookies are deactivated, the functionality of this website may be limited.

Technically necessary cookies/storage

  • csrf-secret (HTTP-only cookie, ~1 hour): CSRF protection.
  • confirmation-status (HTTP-only cookie, ~5 minutes): DOI confirmation status.
  • percol-cookie-consent (LocalStorage, 12 months): Stores your consent preferences.
  • percol-captcha-consent (LocalStorage, 12 months): Stores your activation of Google reCAPTCHA (2‑click).

Server Log Files

The provider of the pages automatically collects and stores information in so-called server log files, which your browser automatically transmits to us. These are:

  • Browser type and browser version
  • Operating system used
  • Referrer URL
  • Host name of the accessing computer
  • Time of the server request
  • IP address

This data is not merged with other data sources.

The collection of this data is based on Art. 6 para. 1 lit. f GDPR. The website operator has a legitimate interest in the technically error-free presentation and optimization of its website - for this purpose, the server log files must be recorded.

Retention: Server log data is typically retained for 14 days and then automatically deleted unless longer retention is required for evidence purposes.

Inquiry by Email, Telephone, or Fax

If you contact us by email, telephone, or fax, your inquiry, including all resulting personal data (name, inquiry), will be stored and processed by us for the purpose of processing your request. We do not pass on this data without your consent.

This data is processed on the basis of Art. 6 para. 1 lit. b GDPR if your request is related to the fulfillment of a contract or is necessary to carry out pre-contractual measures. In all other cases, the processing is based on our legitimate interest in the effective processing of the inquiries addressed to us (Art. 6 para. 1 lit. f GDPR) or on your consent (Art. 6 para. 1 lit. a GDPR) if this has been requested; consent can be revoked at any time.

The data you send to us via contact requests will remain with us until you request us to delete it, revoke your consent to storage, or the purpose for data storage no longer applies (e.g., after your request has been processed). Mandatory legal provisions - in particular statutory retention periods - remain unaffected.

5. Analysis Tools

Vercel Analytics

This website uses Vercel Analytics to analyze user behavior. The provider is Vercel Inc., 440 N Barranca Ave #4133, Covina, CA 91723, USA.

Vercel Analytics collects aggregated usage data about website visits (e.g., page views, referrers, device type, approximate geodata). No cookies are set.

International transfers: A transfer to the USA cannot be ruled out. Safeguards include appropriate guarantees (e.g., EU Standard Contractual Clauses/DPF) by the provider. More info: vercel.com/legal/privacy.

6. Email Notifications (Waitlist)

Waitlist Data

When you join the waitlist, we process your email address and the data you provide solely to perform the double‑opt‑in procedure and to notify you about the start of our open beta. No other purposes are pursued.

Legal basis is your consent (Art. 6(1)(a) GDPR). You can withdraw your consent at any time, e.g., via the one‑click unsubscribe link in our emails or by emailing info@percol.de. The lawfulness of processing prior to withdrawal remains unaffected.

Data is retained until you unsubscribe or for a maximum of 12 months after last activity (confirmation/unsubscribe) and then deleted. See “Email delivery (Resend)” and “Waitlist / Google Sheets” for details on providers and data categories.

7. Plugins and Tools

Google Fonts (Local Hosting)

This site uses so-called Google Fonts provided by Google for the uniform display of fonts. The Google Fonts are installed locally. A connection to Google servers does not take place.

Google reCAPTCHA v3

We use Google reCAPTCHA v3 to protect our forms against abuse and spam. Provider: Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland (parent company: Google LLC, USA).

reCAPTCHA analyzes user behavior to determine whether an interaction is by a human. IP address, device/browser data, mouse/scroll behavior, referrer URL, and dwell time may be processed. We only load reCAPTCHA after your explicit activation (2‑click). Without activation, no data is sent to Google.

Legal basis: Art. 6(1)(f) GDPR (legitimate interest in IT security and spam protection) and—where required—your consent per Art. 6(1)(a) GDPR in conjunction with § 25(1) TTDSG. Transfers to the USA cannot be ruled out. Safeguards include appropriate guarantees (e.g., SCCs/DPF). More info: policies.google.com/privacy.

Retention: We do not retain reCAPTCHA verification results beyond the verification purpose.

Email delivery (Resend)

We use Resend to send transactional emails (e.g., double‑opt‑in). Provider: Resend (EU region/Ireland); data may be processed in third countries (USA) as part of service delivery.

Processed data: email address, name, DOI token, delivery metadata. Legal basis: Art. 6(1)(a) GDPR (consent) and Art. 6(1)(f) GDPR (necessary transactional communications).

International transfers: safeguarded by appropriate guarantees (e.g., SCCs/DPF). You can unsubscribe via the one‑click link provided in emails or by emailing info@percol.de.

8. Our Own Services

Waitlist / Google Sheets

We use Google Sheets to manage waitlist entries and confirmations (double opt‑in). Provider: Google Ireland Limited (parent company: Google LLC, USA).

Processed data: name, email, company, employee count, phone (optional), message (optional), timestamps, consent status, and DOI token. Legal basis: Art. 6(1)(a) GDPR (consent) and, for individual requests, Art. 6(1)(b) GDPR (pre‑contractual measures).

Retention: deletion after 12 months of inactivity or upon request; double‑opt‑in proofs are retained for a reasonable period. The same applies to backups.

International transfers: transfers to the USA cannot be ruled out. Safeguards include appropriate guarantees (e.g., SCCs/DPF).

Handling of Applicant Data

We offer you the opportunity to apply to us (e.g., by email, by post, or via an online application form). Below, we inform you about the scope, purpose, and use of your personal data collected during the application process. We assure you that the collection, processing, and use of your data will be carried out in accordance with applicable data protection law and all other legal provisions and that your data will be treated strictly confidentially.

Scope and Purpose of Data Collection
If you send us an application, we process your associated personal data (e.g., contact and communication data, application documents, notes from job interviews, etc.) insofar as this is necessary for the decision on the establishment of an employment relationship. The legal basis for this is § 26 BDSG under German law (initiation of an employment relationship), Art. 6 para. 1 lit. b GDPR (general contract initiation), and - if you have given consent - Art. 6 para. 1 lit. a GDPR. Consent can be revoked at any time. Your personal data will only be passed on to persons within our company who are involved in processing your application.

If the application is successful, the data you submit will be stored in our data processing systems on the basis of § 26 BDSG and Art. 6 para. 1 lit. b GDPR for the purpose of implementing the employment relationship.

Data Retention Period
If we are unable to make you a job offer, you reject a job offer, or withdraw your application, we reserve the right to retain the data you have transmitted to us on the basis of our legitimate interests (Art. 6 para. 1 lit. f GDPR) for up to 6 months from the end of the application process (rejection or withdrawal of the application). The data will then be deleted and the physical application documents destroyed. The retention serves in particular as evidence in the event of a legal dispute. If it is evident that the data will be required after the 6-month period has expired (e.g., due to an impending or pending legal dispute), deletion will only take place when the purpose for further retention no longer applies.

Longer retention may also take place if you have given appropriate consent (Art. 6 para. 1 lit. a GDPR) or if statutory retention obligations preclude deletion.
