Privacy policy

This policy informs you about which personal data we process when you visit this website and in connection with enquiries and orders, for what purpose and on what legal basis this takes place, and what rights you have. References to the GDPR refer to the General Data Protection Regulation (Regulation (EU) 2016/679).

1. Controller

If you have any questions about data protection or wish to exercise your rights, please use these contact details.

2. Provision of the website (Cloudflare)

This website is provided via Cloudflare Pages. The provider is Cloudflare, Inc., 101 Townsend Street, San Francisco, CA 94107, USA. When you access the website, Cloudflare processes technical connection data on our behalf, such as your IP address, the address accessed, the date and time and information about your browser and operating system, in order to deliver the content and to protect the service against attacks and misuse. The content is delivered via Cloudflare’s global network. We do not analyse this data ourselves and do not create usage profiles.

The legal basis is our legitimate interest in providing the website securely and reliably (Art. 6(1)(f) GDPR). Data may be transferred to the USA in this context. Cloudflare, Inc. is certified under the EU-US Data Privacy Framework; the transfer is based on the European Commission’s adequacy decision for this framework. In addition, Cloudflare’s data processing agreement provides for the European Commission’s standard contractual clauses. Further information: Cloudflare’s privacy policy.

3. No cookies, no analytics, local fonts

This website does not itself set any cookies and does not use any analytics, tracking or advertising services. Fonts and images are delivered together with the website; no content is loaded from Google Fonts, Bunny Fonts or other font services. The exceptions are the Google map, which is only loaded after you click (section 10), and the form service, which is only called up when you submit the contact form (section 6). An overview can be found under Cookies and external services.

4. Colour scheme setting

Using the switch in the page header, you can choose between a light, a dark and a system-dependent colour scheme. Only if you change the setting does your browser save your choice in local storage (localStorage) under the key akku-theme (value “light”, “dark” or “system”). This information remains on your device, is not transmitted to us or to third parties and contains no identifier that identifies you. It is stored only at your instigation and serves solely to provide this function requested by you. You can delete it at any time by removing the site data for this website in your browser settings.

5. Contact by e-mail and telephone

If you contact us by e-mail or by telephone, we process the information you provide – such as your name, contact details, information about the device and battery, photos and the description of the fault – in order to answer your enquiry, prepare a quotation for you and, where applicable, carry out your order. The legal basis is the taking of steps prior to entering into a contract or the performance of a contract (Art. 6(1)(b) GDPR) and, in the case of general enquiries, our legitimate interest in answering them (Art. 6(1)(f) GDPR).

We use Gmail for our e-mail inbox. For users in Europe, the provider is Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland. E-mails to us – including enquiries via the contact form – are therefore stored and processed on Google servers. Data may be transferred to Google LLC in the USA in this context. Google LLC is certified under the EU-US Data Privacy Framework; the transfer is based on the European Commission’s adequacy decision for this framework. Further information: Google’s privacy policy. E-mails to [email protected] reach this inbox via the forwarding service Cloudflare Email Routing (provider: see section 2); according to Cloudflare, the content is not stored in the process.

6. Contact form (FormSubmit)

If you use the contact form, we process your name, your e-mail address and your message and – if you provide them – your telephone number, information about the device and battery and uploaded photos. The purpose and legal bases are the same as in section 5.

The form is transmitted via the external service FormSubmit (formsubmit.co, operator: Devro LABS), which forwards your details by e-mail to our inbox. The service is only called up when you submit the form, not when you open the page. When you submit the form, your browser connects to FormSubmit; in the process, your form entries and technical connection data such as your IP address are transmitted to FormSubmit. According to its documentation, FormSubmit keeps submissions available for retrieval for up to 30 days; according to its information, uploaded files are not stored in this archive.

When the form is submitted, FormSubmit may use a spam protection check with Google reCAPTCHA. In this process, Google processes information such as your IP address and information about your browser and your use of the verification page, and may set cookies. FormSubmit does not state its registered office or server locations; processing outside the European Economic Area, in particular in the USA, therefore cannot be ruled out. The form is used on the basis of our legitimate interest in offering a simple means of contact (Art. 6(1)(f) GDPR).

Please only submit information that is necessary for your battery enquiry and do not send copies of identity documents or other sensitive documents. If you do not wish to use the form service, please write to us directly by e-mail or call us.

7. Quotations, orders and invoices

For quotations, the performance of your order and invoicing, we process your contact and order data, information about the battery, agreed prices and payment information (Art. 6(1)(b) GDPR). We retain invoices and other accounting records because we are legally obliged to do so (Art. 6(1)(c) GDPR).

8. Payment

PayPal: If you pay with PayPal, the data required for the payment – for example name, e-mail address, amount and payment reference – are transmitted to PayPal (Europe) S.à r.l. et Cie, S.C.A., 22–24 Boulevard Royal, L-2449 Luxembourg. PayPal processes this data as an independent controller in accordance with its own privacy provisions. The legal basis for the transfer is the performance of the contract (Art. 6(1)(b) GDPR). Further information: PayPal’s privacy statement.

Payment in advance by bank transfer and cash payment: In the case of a bank transfer, the banks involved process the payment data. In the case of cash payment on collection, no payment data is transmitted to third parties.

9. Return shipping

For the return shipping of your battery, we pass on your name and delivery address to the shipping service provider we have commissioned. The legal basis is the performance of the contract (Art. 6(1)(b) GDPR).

10. Google Maps

On the “About us” and “Legal notice” pages, you can display a map from Google Maps. The map is not loaded automatically, but only when you click “Show Google map”; only then does your browser establish a connection to Google. The provider is Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland. In this process, Google receives in particular your IP address and technical information about your browser, may use cookies or similar technologies and may transfer data to Google LLC in the USA (EU-US Data Privacy Framework, see section 5).

By clicking, you consent to the loading of the map and the associated data processing. The legal basis is your consent (Art. 6(1)(a) GDPR; for the storage of and access to information on your terminal equipment, Art. 4(3)(e) of the Luxembourg Law of 30 May 2005 on data protection in electronic communications). Your choice is not saved: after the page is reloaded, the map is only displayed again after a new click. You can withdraw your consent at any time with effect for the future by closing or reloading the page and deleting cookies set by Google in your browser.

11. Google reviews

On the home page, we show excerpts from publicly available Google reviews of Akku New with abbreviated names of their authors. The excerpts are embedded as fixed text; no connection to Google is established when the page is accessed. The legal basis is our legitimate interest in giving prospective customers an impression of the experiences of other customers (Art. 6(1)(f) GDPR). If you are the author of a review and do not wish to be named here, please let us know; we will then remove the excerpt.

12. Links to other websites

Our pages contain links to other websites, for example to Google Maps, to public authorities or to sources. Only when you open such a link does your browser access the third-party website; the privacy information of the respective provider applies to that visit.

13. Storage period

• Enquiries without an order: We delete them no later than six months after the last contact.
• Orders: We retain quotations, order documents and correspondence for as long as this is necessary for processing the order and for possible warranty claims.
• Invoices and other accounting records: We retain them for ten years (Art. 16 Code de commerce).
• Contact form: According to its own information, FormSubmit keeps submissions for up to 30 days (section 6).
• Colour scheme: The setting remains stored in your browser until you delete it (section 4).

14. Obligation to provide data

You are under no statutory or contractual obligation to provide us with personal data. However, without your contact details and information about the battery, we cannot answer your enquiry or carry out an order.

15. Your rights

Subject to the provisions of the GDPR, you have the right of access to the data we hold about you (Art. 15 GDPR), the right to rectification (Art. 16 GDPR), to erasure (Art. 17 GDPR), to restriction of processing (Art. 18 GDPR) and to data portability (Art. 20 GDPR).

You can withdraw any consent you have given at any time with effect for the future (Art. 7(3) GDPR). This does not affect the lawfulness of processing carried out before the withdrawal.

To exercise your rights, simply contact us informally using the contact details given in section 1.

16. Right to object

Your right to object under Art. 21 GDPR: Where we process your data on the basis of our legitimate interest (Art. 6(1)(f) GDPR), you have the right to object to this processing at any time on grounds relating to your particular situation. We will then no longer process your data unless we can demonstrate compelling legitimate grounds for the processing which override your interests, rights and freedoms, or the processing serves the establishment, exercise or defence of legal claims. You can send your objection informally to the contact details given in section 1.

17. Complaint to the supervisory authority

You have the right to lodge a complaint with a data protection supervisory authority (Art. 77 GDPR), in particular in the Member State of your habitual residence, your place of work or the place of the alleged infringement. The authority responsible for us is the Commission nationale pour la protection des données (CNPD), 15, boulevard du Jazz, L-4370 Belvaux, Luxembourg.

18. No automated decision-making

We do not make any decisions based solely on automated processing (Art. 22 GDPR) and do not carry out profiling.
