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 injection cycles, calculate reconstitution ratios, visualise half-life curves, track meals and macros from a photo, and browse a reference section. It records what you did; it does not tell you what to take.

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. What costs money, and who you buy it from

The free tier is available without payment and stays free. Everything paid is 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. We are your contractual partner for the service itself — the account, the data and the features Apple's receipt unlocks. Nothing is charged on this website.

Two things are sold, and they behave differently

• Pro — an auto-renewing subscription. €9.99 per month or €89.99 per year, each with a seven-day free trial. It renews 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 period you already paid for, and no separate notice to us is needed.
• Scan packs — a one-off purchase, not a subscription. Bundles of 5, 20, 50 or 100 photo analyses, priced from €1.99 to €12.99. They are charged once, they never expire, they do not renew, and there is nothing to cancel. Credits are consumed one per analysis and remain yours even if a Pro subscription lapses.

Prices are the final amounts shown in the App Store before you confirm, in your storefront's currency and inclusive of any VAT Apple applies. Apple, not we, sets the local price point for each currency.

Right of withdrawal

As a consumer you have a statutory right to withdraw from a distance contract within 14 days (§ 355 BGB). Because the purchase contract is concluded with Apple, that right is exercised against Apple, through reportaproblem.apple.com or your Apple ID purchase history.

For digital content supplied without a physical medium — which is what both a scan pack and an unlocked Pro period are — the right of withdrawal lapses early under § 356 (6) BGB once performance has begun, but only if you expressly agreed to that early start, confirmed that you understood you would lose the right, and received Apple's confirmation of the contract (§ 312f BGB). Apple collects that agreement as part of the purchase flow. Until all three conditions are met, the right survives. Apple also grants refunds beyond the statutory minimum at its discretion, and your statutory rights are unaffected either way.

Legacy website subscriptions

Subscriptions taken out on the website before web checkout closed continue to run through Stripe and can be cancelled from Settings. No new contracts are concluded this way.

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, and only you can do it.

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. Deleting your account in the app or on the website erases your data immediately and irreversibly, not after a waiting period; billing records held for legal compliance (§ 147 AO) are the only exception, and for in-app purchases those sit with Apple. Terminating the account does not cancel an App Store subscription — see § 6.

9. Disclaimers & liability

The Service is provided on an "as is" and "as available" basis, but only to the extent the law allows: your statutory rights as a consumer are not excluded or limited by this section. For digital products we owe you the conformity and the updates required by §§ 327 ff. BGB, in particular the update obligation under § 327f BGB, for as long as you can reasonably expect them.

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. If you are a consumer resident in the EU, this choice of law does not deprive you of the protection of the mandatory rules of your own country (Art. 6 (2) Rome I).

Where you are a merchant, a legal entity under public law or a special fund under public law, the place of jurisdiction is Stade, the seat of our business. For consumers, the statutory forum applies and cannot be varied by these Terms.

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.
