Terms.

1. Agreement

By creating an account or otherwise using pinning ("the Service"), you ("you") agree to these Terms of Service ("Terms") between you and Aleksander Chadzy, sole trader, trading as "pinning" ("pinning", "we"), Graf-Heinrich-Str. 1, 21698 Harsefeld, Germany. If you do not agree, do not use the Service.

2. What pinning is — and is not

pinning provides software to log peptide cycles, calculate reconstitution ratios, visualise half-life curves, track meals and macros from a photo, and browse a knowledge base.

pinning is not:

• A medical professional, doctor, or pharmacist
• A pharmacy, distributor, or marketplace
• A medical device under MDR (EU 2017/745)
• A substitute for clinical advice, diagnosis, or treatment

Information presented is collected from public scientific literature and community submissions. None of it constitutes medical advice. See also our § 95 AMG notice.

3. Eligibility

• You must be at least 18 years old
• You must have the legal capacity to enter contracts in your jurisdiction
• You may not use the Service from any jurisdiction where it is illegal to do so

4. Acceptable use

You agree not to:

• Use the Service to advertise, broker, or transact the sale of pharmaceuticals or research chemicals
• Scrape, reverse-engineer, or resell our knowledge base data
• Impersonate others, abuse other users, or post unlawful content
• Bypass rate limits, authentication, or any technical protection

5. Your content

You retain ownership of all data you upload (cycles, logs, meals, photos). You grant pinning a non-exclusive license to host, display, and process this content solely to operate the Service.

You can download everything stored under your account at any time from Settings (Art. 20 GDPR), free of charge.

6. Subscriptions & billing

The free tier is available without payment. Paid plans are bought inside the iOS app as an In-App Purchase. In that case Apple is your contractual partner for the purchase and the seller of record: billing, invoices, cancellation, withdrawal and refunds run through your Apple ID, under Apple's Media Services Terms.

• Prices are shown in the app before purchase and include VAT
• Subscriptions renew automatically until cancelled. Cancel at least 24 hours before the end of the current period in iOS Settings → your name → Subscriptions
• Cancellation takes effect at the end of the current billing period
• Refunds and the statutory right of withdrawal for the purchase are handled by Apple (reportaproblem.apple.com). Your statutory rights remain unaffected.
• Subscriptions taken out on the website before web checkout closed continue to run through Stripe and can be cancelled from Settings

Deleting the app or your pinning account does not cancel an App Store subscription — that has to be done in your Apple ID subscription settings.

7. Service availability

We aim for 99.5% monthly uptime but provide no formal SLA on free or self-serve plans. Planned maintenance is announced at least 48 hours in advance.

8. Termination

Either party may terminate at any time. We may suspend or terminate accounts that violate these Terms. Upon termination, your data is deleted within 30 days, except billing records retained for legal compliance (§ 147 AO).

9. Disclaimers & liability

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE". TO THE EXTENT PERMITTED BY LAW, PINNING DISCLAIMS ALL WARRANTIES.

For damages arising from slight negligence, pinning is liable only for breach of material contractual obligations (Kardinalpflichten), limited to typical foreseeable damages. Liability for intent, gross negligence, injury to life, body, or health, and under the Product Liability Act remains unaffected.

10. Governing law & jurisdiction

These Terms are governed by German law, excluding the UN Convention on Contracts for the International Sale of Goods. Exclusive jurisdiction is Berlin for merchants. For consumers, the statutory forum applies.

11. Consumer dispute resolution

The European Commission's ODR platform was shut down on 20 July 2025 by Regulation (EU) 2024/3228 and is no longer available. We are not willing or obliged to participate in dispute resolution proceedings before a consumer arbitration board (§ 36 VSBG). Your statutory rights and access to the ordinary courts remain unaffected.

12. Changes to the Terms

We may update these Terms. Material changes will be announced by email at least 30 days in advance. Continued use after the effective date constitutes acceptance.
