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 pinning UG (haftungsbeschränkt) i.G. ("pinning", "we"). 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, visualize half-life curves, browse a knowledge base, and read/write vendor reviews.

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
• Post reviews you know to be false or that you cannot back with proof of purchase
• 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, reviews, photos). You grant pinning a non-exclusive license to host, display, and process this content solely to operate the Service.

Published reviews remain visible after account deletion in pseudonymized form, unless you specifically request removal at hello@pinning.info.

6. Subscriptions & billing

• Free tier is available without payment

• Right of withdrawal (§ 312g BGB) applies for 14 days from purchase

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. EU Online Dispute Resolution

EU consumers may use the European Commission's ODR platform: ec.europa.eu/consumers/odr. We are not obligated to participate in dispute resolution before a consumer arbitration board.

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.
