Terms of service



Thank you for using Regstones to evidence your copyright. By using our service, you accept the following conditions:

Description of our service

The Regstones service (“service”) is to produce a PDF-formatted certificate (the “evidence document”) that contains your identity and a digital fingerprint of a file of your choice (a song, a partition or similar, max. 50 MB; in the following “file”), to seal it by injecting a digital timestamp token and by applying Long-Term Validation (“LTV”) enabled signature.

The fingerprint generated from your file is called a “hash”. We use the SHA-256 algorithm for the hashing (if you wish to dig deeper, you can read more about it here). The cryptographic hash process is impossible to invert, so nobody can reverse-engineer a file that produces the same hash as your file. This means also that your evidence document will not match with any other file. THEREFORE, IT IS PARAMOUNT THAT YOU KEEP YOUR MUSIC FILE STORED FOR AS LONG AS YOU KEEP THE EVIDENCE DOCUMENT, IDEALLY TOGETHER. ONLY BOTH ELEMENTS COMBINED DELIVER THE VALUE AS COPYRIGHT EVIDENCE.

Applied signature, timestamp and timestamp provider

We source each digital signature, including the timestamp token, from a European Union trust service provider with certified compliance with the eIDAS regulations and ETSI EN 319 421. The accuracy of each provided timestamp is within one second with respect to universal time (UTC).

The applied signatures are LTV-enabled (LTV = “Long-Term Validation”). The document can confirm at any time in the future that the signature and all related certificates were valid at the time of signature.

Your obligations as users of the service

By using the service, you guarantee that:

  • you are indeed the copyright owner of the art or creative works contained in the file and that you hold the necessary rights to use the file;
  • the content of the file is legal and does not enable illegal or fraudulent acts, and does not infringe the intellectual property rights of a third party;
  • the content of the file does not infringe the private life of persons and/or their rights to their image and/or ownership of property rights and/or the provisions relating to personal data protection of third parties and/or competition law and/or consumer law;
  • where necessary, if you act as a trader or have professional use of our service, that you comply with the obligations incumbent upon you due to your status.

You shall be solely liable for using the service outside of these guarantees.

Reception of the evidence document and signature validation

You will receive the evidence document per email, additionally you have the possibility to directly download it upon completion of the sealing process. The document is an Adobe PDF document.

You will need a current release of the regular Adobe Acrobat Reader, you can download the latest release free of charge from adobe.com. Limited apps or so-called preview apps are not able to handle advanced signature functionalities.

The Reader will validate all signatures upon opening the document. You need to accept if the Reader suggests an update of the list of trustworthy certificates; without this update the Reader will not be able to handle the digital signatures.

Our YouTube Channel contains a short look into your evidence document and where to find the advanced features.

It is your sole responsibility to

  1. keep this evidence document and store it with the required care and in a way, that is suitable for long-term storage. We do not keep a back-up version of your evidence package.
  2. keep the same file that you used for the creation of the evidence document, ideally next to the evidence document. Only both elements together deliver the value as copyright evidence. We do not keep a back-up copy of your file.

Price of using our service and payments

The cost of one service is 2,99€. We offer PayPal as payment channel, and we carry the fees related to the payment transaction. We do not charge VAT as we are VAT-exempt as of § 19 UStG (German VAT code).

If you want to process a higher volume of files e.g. through API or batch processing, please contact us via hello@regstones.com, we can flexibly cater for specific needs.

Promocode concept

Regstones offers a promocode concept that is aimed at minimizing marketing spent and at giving you the saved money back. To participate in the promocode concept, simply tick the corresponding promocode box during the use of our service.

When you opted in and after completion of the checkout process, you will receive an email with your personal promocode. This promocode is connected to your email address, and of unlimited validity. We only distribute one promocode per user email address. That is why the promocode participation tick box will disappear for users/email addresses that have already received a promocode.

We invite you to distribute your promocode generously to everybody who you know who might be interested in our service: each time when a new user uses your promocode he/she will benefit of a discount of 50%, and additionally you will receive a credit for 1 free copyright certificate. Each new user can only use the promocode once, but you get credits without limitation for every new user. We ensure that you get a notification each time when your promocode got credited.

To use your credits, simply make sure to use our service with the email address connected to your promocode. Your available credits balance will then automatically be displayed during checkout, and available credits will be automatically used to ensure you get a certificate free of cost.

If you want to step out of the promocode concept, simply send a message to hello@regstones.com with the subject “stop promocode”. Upon reception of this message, Regstones will ensure no further promocode notifications are sent to you, and your credits balance will be set to zero. Your promocode will however continue to help new users taking advantage of the discount.

Disclaimer to the promocode concept

The promocode concept is a voluntary offer by Regstones with the goal of offering best possible prices to creative artists. The concept is intended to distribute back to musicians saved marketing funds. This concept is a trial in the market at unclear success and represents by this a stake of the client in the success of Regstones.

Regstones reserves the right to amend conditions under the promocode concept. This means in particular:

  1. There is no entitlement of a client to obtain a promocode, nor to specific conditions that a promocode may offer.
  2. Regstones can deploy operational changes: Conditions of promocodes, even after having been distributed, can be changed by Regstones at any point in time and promocodes can be cancelled by Regstones without prior information to the promocode holder or to the prospective client. Already accrued credits shall be protected in such case.
  3. Regstones may furthermore at any point in time decide to stop the entire promocode concept as such. Regstones is free to decide about the proceeding of such stop.

By using the service, the client accepts the volatile nature of the promocode concept and promocodes, and will hold Regstones free of any possible claim related to the change or stop of individual promocode conditions, individual promocodes, or the promocode concept as such. Accrued credits shall remain valid in line with their initial validity period unless a major event occurs.

In case of a major event, Regstones can exceptionally decide to cancel immediately and without any service in return, credits already accrued by promocode holders. A major event can be, among others, Regstones facing a financial loss to its annual operations, a planned substantial change to its business model, a case of ownership change, or when the website is out of service for longer than 4 weeks for any reason. In case of such exceptional decision, the promocode holder agrees to hold Regstones, its previous, present, and planned owners, free of any claim related to the cancellation of credits, and endorses the loss of accrued credits as a loss in a shared objective to make Regstones and its promocode concept successful.
