Terms and Conditions

These General Terms and Conditions (Terms) apply to the use of Tailwind Inbox (website, web app and all related services). The provider is Crafted Webstudio GmbH, Ägeristrasse 17, 6300 Zug, Switzerland (“we”). Contact: datenschutz@crafted-webstudio.ch.

By creating an account and confirming during onboarding, you accept these Terms. Users’ own terms do not apply.

Tailwind Inbox brings email, WhatsApp and Telegram together in one place. Artificial intelligence (AI) classifies messages, summarises, writes reply drafts, transcribes voice messages and dictation, and searches your messages.

Tailwind Inbox is in its launch phase and experimental. Features may change, be restricted or be discontinued. There is no entitlement to specific features, a specific quality of results or uninterrupted availability.

• Only people who are at least 18 years old and have legal capacity may create an account.
• Your details must be correct. You keep your login details secret and are responsible for everything that happens through your account.
• An account is personal and not transferable.
• We may refuse a registration without giving reasons, for example while a waitlist is in place.

You connect your own accounts (e.g. Gmail or other mailboxes, WhatsApp, Telegram, address books). You may only connect accounts you are entitled to use, and you are responsible for ensuring that using them through Tailwind Inbox is compatible with those providers’ terms.

WhatsApp and Telegram are connected through bridges that are neither made nor supported by those providers. They may restrict such use or suspend accounts at any time. You bear this risk yourself; we are not liable for suspensions, restrictions or data loss at third-party providers.

Third-party providers may change or switch off their interfaces at any time. If features of Tailwind Inbox are lost in whole or in part as a result, this gives rise to no claims.

AI results (classifications such as “important” or “urgent”, summaries, drafts, transcriptions, search answers, suggestions) are generated automatically. They may be wrong, incomplete or inappropriate.

• Check every draft before you send it. You alone are responsible for what you send.
• Do not rely on Tailwind Inbox to recognise or correctly classify important or urgent messages or to notify you of them. Deadlines and appointments remain your responsibility.
• AI results are not legal, medical, financial or other professional advice.

For the AI features we pass content to providers such as Anthropic and OpenAI. Details are in the privacy policy.

You use Tailwind Inbox only within the law. In particular, you may not:

• send spam, bulk advertising or harassing messages, including through the invite feature — only invite people you know;
• infringe third-party rights (e.g. personality rights, copyright or trademarks) or process unlawful content;
• disrupt or overload Tailwind Inbox, circumvent protective measures, scrape it automatically or copy it;
• let third parties use your account or resell Tailwind Inbox without our consent.

In the event of a breach we may remove content, restrict features or suspend or terminate the account immediately.

Your messages and content remain yours. You allow us to store and process them and to pass them on to the services needed for the features, to the extent required to operate Tailwind Inbox. We do not use your content to train AI models.

The software, design, texts and trademarks of Tailwind Inbox belong to Crafted Webstudio GmbH. For the term of the contract you receive a simple, non-transferable right to use Tailwind Inbox for yourself.

We may freely use feedback, ideas and bug reports you send us, without any remuneration being owed.

Using Tailwind Inbox is currently free of charge.

Free days and other credits (e.g. for invitations, confirmed bug reports or surveys) have no cash value, are not transferable and cannot be paid out. There is no entitlement to them; we may change or end the rules for them.

We strive for reliable operation but do not guarantee any particular availability. Interruptions for maintenance, updates or due to faults are possible, including without prior notice.

Tailwind Inbox is not an archive. The originals of your messages remain with your email provider and on your phone; some content is deleted after fixed periods (see privacy policy). Back up anything important yourself.

We are only liable for damage caused intentionally or through gross negligence. Liability for slight negligence is excluded, as is — to the extent permitted by law — liability for auxiliary persons and third parties we engage.

To the extent permitted by law, we are in particular not liable for:

• indirect and consequential damage, loss of profit, missed deadlines or appointments;
• wrong, incomplete or missing AI results, wrong classifications and missing or delayed notifications;
• content you send through Tailwind Inbox and its consequences;
• actions, outages, suspensions or changes by third-party providers (e.g. email providers, WhatsApp, Telegram, AI providers);
• data loss and interruptions or restrictions of the service;
• damage caused by force majeure, attacks by third parties or events beyond our control.

Should Tailwind Inbox become subject to charges in future, our liability is limited — to the extent permitted by law — to the amount you paid in the twelve months before the event causing the damage.

Mandatory statutory liability remains reserved, in particular for personal injury and under product liability law, as do mandatory consumer protection provisions.

If third parties assert claims against us because you used Tailwind Inbox unlawfully or contrary to these Terms (e.g. because of content you sent or unwanted invitations), you indemnify us against them and reimburse the reasonable costs of legal defence, to the extent permitted by law.

How we handle your data is described in the privacy policy. It is not part of these Terms.

The contract runs for an indefinite period.

• You may terminate at any time without notice by deleting your account or writing to datenschutz@crafted-webstudio.ch.
• We may terminate with 30 days’ notice by email or discontinue Tailwind Inbox entirely with the same notice.
• For good cause, in particular a breach of these Terms, we may suspend or terminate immediately.

After the end of the contract we delete your data within 30 days. Copies in backups disappear when those expire. Statutory retention obligations remain reserved.

We may change these Terms. We will announce material changes at least 30 days before they take effect, in the app or by email. If you do not agree, you may terminate before then. If you continue to use Tailwind Inbox after they take effect or confirm the new version, it is deemed accepted.

Swiss law applies, excluding its conflict-of-laws rules and the UN Convention on Contracts for the International Sale of Goods (CISG).

The place of jurisdiction is Zug, Switzerland. If you are a consumer, you may also sue and be sued at your place of residence; mandatory places of jurisdiction and the mandatory law of your country of residence remain reserved.

If any provision of these Terms is wholly or partly invalid, the remaining provisions remain valid. The invalid provision is replaced by one that comes closest to its purpose within what the law permits.

These Terms exist in German and English. The German version prevails.
