At a glance: Try 3 days free · then €7.77/month · cancel anytime. Cancel within the 3 days and nothing is charged. The details are set out below.

§ 1 Scope and provider

(1) These General Terms and Conditions (“Terms”) apply to the subscription to the app “777Hz” at 777hz.pages.dev. 777Hz is offered by Semih Inac (777Project). Your contractual partner is Semih Inac, 777Project, Glogauer Str. 14, 76139 Karlsruhe, Germany, email: info@777project.de (“we”, “us”).

(2) The app is only available with the subscription; it begins with 3 free days (§ 6). Without a subscription the app only shows its overview; viewing the overview does not create a contract.

(3) A consumer is any natural person who enters into a legal transaction for purposes that are predominantly outside their trade, business or profession (§ 13 BGB).

(4) Deviating terms of the customer do not become part of the contract.

(5) We currently do not offer the subscription in the United Kingdom. If you are there, the order page tells you so and no order can be placed. If it only turns out at PayPal that your PayPal account is registered there, no contract is concluded; we end the subscription at PayPal immediately, refund anything PayPal may already have collected and let you know by email.

§ 2 Service

With the subscription you can use all 23 worlds of the app in full, each with its picture and its music, plus the ambient sounds, the frequency tones, the mix, the sleep timer and the world “Your Sound Pattern”, which calculates a sound pattern from a first name and lets you save it as a picture. Without a subscription the app only shows its overview. We owe the worlds as they are described in the app when the contract is concluded. New worlds may be added; there is no entitlement to them. We may technically adjust or improve individual worlds as long as this does not reduce the scope and causes you no costs; otherwise § 327r BGB applies. The worlds are meant for relaxation and entertainment. They do not replace medical treatment; we do not promise any healing effect – and the name “777Hz” is just a name.

§ 3 Technical requirements

The app runs in the browser (a current browser with JavaScript and WebGL is required) and can be added to the home screen. The music loads over the internet the first time you play it and is then available on your device without a connection. There is no copy protection.

§ 4 Access without a password

After the contract is concluded we send you a personal access link by email. When you open it on a device, the subscription is unlocked in that browser; this works on all your devices. You can request a new link at any time in the app via “Resend your link”. The link is personal: please do not pass it on to others. If a link is evidently being shared publicly, we may block it and send you a new one.

§ 5 Conclusion of the contract

On the page “Try 3 days free” (777hz.pages.dev/subscribe/) you enter your email address; before you submit, you see the service, the trial, the price, the term, the cancellation terms and the date of the first charge. Until then you can correct input errors in the form field. By clicking “Subscribe now – payment required” you make a binding offer to conclude the subscription under these Terms, which are referred to directly above the button; we confirm its receipt by email immediately. You are then taken to PayPal, where you choose a payment method and agree to the subscription and the monthly charges. The contract is concluded as soon as PayPal reports the subscription to us as active. We confirm the conclusion of the contract to you by email without delay, together with your access link, the end of the trial, the date of the first charge, these Terms and the information on the right of withdrawal (contract confirmation). We store the text of the contract; you can view, print and save these Terms on this page at any time. If you cancel at PayPal or PayPal declines, no contract is concluded and nothing is charged. The contract language is English; the German version of these Terms is available at 777hz.pages.dev/agb/.

§ 6 Trial

The subscription begins with a free trial of 3 days from the conclusion of the contract. If you cancel during this time, nothing is charged, and the app stays unlocked until the end of the trial. If you do not cancel, the subscription continues at the end of the trial as the paid monthly subscription at €7.77 per month, without any further declaration; we remind you by email about a day before. The trial is available once per person: once per email address and once per PayPal account. If the email address you entered has already been used for a trial, we offer you the subscription without a trial before you submit. If it only turns out at PayPal that the PayPal account has already used the trial, no contract for another trial is concluded; we then end the subscription at PayPal immediately, without anything being charged, and let you know by email.

§ 7 Price and payment

After the trial the subscription costs €7.77 per month (without a trial: from the first day). This is a final price; as a small business under § 19 UStG (German VAT Act) we do not charge VAT. The monthly price is charged through a PayPal subscription one month in advance each time, the first time at the end of the trial (without a trial: when you subscribe). Payment is processed by PayPal (Europe) S.à r.l. et Cie, S.C.A., 22–24 Boulevard Royal, L-2449 Luxembourg; PayPal's terms also apply. There are no further costs.

§ 8 Term and cancellation

After the trial the subscription runs for one month and is then extended by one further month at a time unless it is cancelled. You can cancel at any time without notice: during the trial with effect from its end, without anything being charged; afterwards at the end of the month already paid for, or on a later date if you wish. You can cancel via the “Cancel contracts here” button at the bottom of every 777Hz page (777hz.pages.dev/cancel/), by email to info@777project.de or in your PayPal account. We confirm every cancellation by email. After the cancellation we charge nothing more; the app stays unlocked until the end of the trial or of the paid month. The right to terminate for good cause remains unaffected.

§ 9 Rights of use

For the term of the contract you receive the simple, non-transferable right to use the app for private purposes. You may use the pictures you create with “Save picture” in “Your Sound Pattern” privately, print them and share them on your private channels. You may not copy, distribute, publicly perform or commercially use the music, the worlds or the app.

§ 10 Defects

The statutory provisions on contracts for digital products apply (§§ 327 ff. BGB). If the app does not work as described, please write to us at info@777project.de.

§ 11 Right of withdrawal

Consumers have a statutory right of withdrawal; the information on the right of withdrawal on the page 777hz.pages.dev/right-of-withdrawal/ applies. You can withdraw online at 777hz.pages.dev/withdraw/. If, when subscribing, you expressly agree that we may begin performing the contract before the withdrawal period ends and confirm that you are aware that you thereby lose your right of withdrawal, the right of withdrawal expires when performance begins, after we have confirmed the contract including this consent to you by email (§ 356(6) no. 2 BGB). Without this consent we still unlock the app right away; your right of withdrawal then remains in place for fourteen days from the conclusion of the contract.

§ 12 Liability

(1) We are liable without limitation for intent and gross negligence, for injury to life, body or health, and under the German Product Liability Act (Produkthaftungsgesetz).

(2) In the case of a slightly negligent breach of an essential contractual obligation – an obligation whose fulfilment makes the proper performance of the contract possible in the first place and on whose observance you may regularly rely – our liability is limited to the foreseeable damage typical for this type of contract. Otherwise, liability for slight negligence is excluded.

§ 13 Dispute resolution

We are neither willing nor obliged to take part in dispute resolution proceedings before a consumer arbitration board.

§ 14 Final provisions

The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods. For consumers, this choice of law applies only insofar as it does not deprive you of the protection afforded by the mandatory provisions of the law of the country in which you have your habitual residence.
