Terms

Effective: June 17, 2026

i. Who’s behind Zapfä

Zapfä is published by Redwood Strategy Labs, a registered DBA of Redwood Strategy Partners LLC, a California limited liability company (2108 N St STE N, Sacramento, CA 95816, United States). When these terms say “we,” “us,” or “Zapfä,” that’s who we mean. When they say “you,” that’s you.

These terms are an agreement between you and us — not between you and Apple, not between you and anyone else. By creating an account or using the app, you’re accepting them.

ii. What Zapfä provides

Zapfä is a personal wine cellar management app. It helps you track the bottles you own, log the ones you uncork, rate vintages, scan labels with your camera, and get AI-assisted suggestions about which bottle to open tonight.

Zapfä has a free tier and paid subscriptions; §viii covers how billing works. The free tier is limited to a set number of bottles in your active cellar. If you’re over that limit when you join or when the cap changes, nothing you’ve added is taken away: your existing bottles stay fully yours and visible, you just won’t be able to add new ones on the free tier. We’ll always announce changes like that in advance (§xiii) rather than springing them on you, and your data stays yours and exportable no matter which tier you’re on.

One thing Zapfä is not: a place to buy or sell wine. We don’t sell alcohol, broker it, or deliver it. The app manages bottles you already own.

iii. Who can use Zapfä

Zapfä is an app about wine, so there’s an age line: you must be of legal drinking age in your jurisdiction to use it — that’s 21 in the United States, where Zapfä is offered at launch, and never younger than 18 anywhere. By using Zapfä you confirm you meet the age requirement that applies to you.

If we learn an account belongs to someone under the applicable age, we’ll close it. If you’re a parent or legal guardian and believe someone under the applicable age has opened an account, email support@zapfae.com and we’ll take care of it.

iv. Your account

You can sign in with Apple or with an email address and password. Either way, the account is yours: keep your credentials to yourself, and you’re responsible for what happens under your account. If you think someone else has gotten into it, tell us right away at support@zapfae.com and we’ll help you lock it down.

One person, one account. Don’t impersonate anyone, and don’t sign up on someone else’s behalf without their permission.

v. Your content — and the shared catalog

Your cellar data, tasting notes, ratings, and label photos belong to you. We are the custodian, not the owner. We need a narrow technical license to do our job — to host, process, back up, and display your content back to you — and that’s the only license we take over your personal content. It ends when you delete the content or your account.

Label photos get an even narrower deal: we don’t store them at all. A photo is processed transiently to read the label (§vi), then deleted from our systems; the original lives only on your device. The details are in the Privacy Policy.

There’s one category that works differently, and we want to be upfront about it: catalog contributions.

When you add a wine that isn’t in Zapfä’s catalog yet — the producer, the wine’s name, the vintage, the grapes — that factual wine data can be promoted into the shared catalog, so the next person who scans the same bottle gets a match instead of typing everything again. The catalog is built by its users, and it only works if entries stay put. So for catalog contributions (and only those), you grant us a perpetual, non-exclusive, royalty-free license to use, store, display, and share that wine data with other Zapfä users, including after you leave.

To be precise about what that means:

Catalog contributions are facts about wine, not about you. Producer, name, vintage, grape composition. Your tasting notes, ratings, and photos are never part of the shared catalog.
You were anonymous from the start. Other users never see who contributed a catalog entry.
If you delete your account, the catalog entry stays — your connection to it doesn’t. The link between you and your contributions is permanently severed, and the wine data lives on, fully anonymized.
You can also cut your link to your contributions without deleting your account, from in-app Settings. Contributions that haven’t yet entered the shared catalog are deleted outright; ones already in the catalog stay there, with your connection to them severed — same as account deletion. If a bottle still in your cellar depends on one of your contributions, you’ll be asked to deal with that bottle first.

Zapfä owns the app, its design, its code, and the shared catalog as a compiled dataset. You own your stuff. That division stays clean.

vi. AI features

Zapfä uses AI to read wine labels from your photos and to make suggestions. Two things you should know:

AI is opt-in, and you can opt out. AI features only run if you’ve turned on AI processing in the app — the consent is enforced on our servers, not just in the interface. You can withdraw consent anytime in Settings; AI features simply stop working until you turn them back on. Without AI consent, the label-scanning engine is off — but the rest of the app works exactly the same, and you can always add and manage bottles manually. (Data already processed is handled per our retention rules — see the Privacy Policy.)

AI gets things wrong. Label extraction can misread a vintage, match the wrong producer, or guess a grape composition that isn’t on the label. AI suggestions are informational, not advice — not sommelier advice, not health advice, and definitely not allergen or alcohol-content information you should rely on before serving someone. Check the bottle.

When AI features run, your label photo travels through our servers to the AI providers listed on our subprocessor page, under contracts that prohibit them from using your data to train their models. They may hold the data briefly for abuse monitoring under their published policies, then delete it — and we delete the photo from our systems once the label is read (§v). We don’t sell your data to anyone — AI providers included.

vii. Acceptable use

A short list, in plain English:

Don’t try to scrape, reverse-engineer, or attack the service — that includes the AI pipeline and bulk-extracting the shared wine catalog.
Don’t upload content that’s illegal, infringing, or that doesn’t belong to you. The photo features are for wine labels and your cellar — nothing else.
Don’t use Zapfä to harass, defame, or abuse anyone.
Don’t use Zapfä to sell alcohol, run unauthorized commerce, or facilitate getting alcohol to anyone under legal drinking age.
Use the service fairly. We enforce rate limits server-side; working around them counts as not using it fairly.

If you do any of the above, we reserve the right to suspend or terminate your account.

viii. Subscriptions

Zapfä offers subscriptions billed exclusively through the Apple App Store — it’s the only distribution channel for the iOS app. Subscriptions are auto-renewing: once you start one, Apple charges your Apple ID on each renewal date until you cancel. You can cancel anytime, with no fee for cancelling, by opening iOS Settings → your name → Subscriptions → Zapfä. Cancelling stops the next renewal; you keep paid access through the end of the current period.

Subscription prices are shown in the app at purchase time, in your local currency, and may vary by region. All billing — pricing, billing cycles, cancellation, refunds — is handled by Apple under Apple’s terms. We never see your payment details. Refund requests go to Apple, not to us, under Apple’s standard refund policy; if something on our side went wrong, write to us and we’ll support your request with Apple. Subscriptions are eligible for Family Sharing: if you share your Apple ID family with up to five other people, they can use your subscription on their own Apple IDs without paying again.

The free tier of Zapfä is currently 30 bottles — meaning the bottles in your active cellar (not the ones you’ve uncorked, gifted, or marked broken). Manage more than that and you’ll be asked to subscribe. If the free-tier cap ever changes, we’ll announce it under §xiii before it does, and your existing bottles are never taken away — see §ii.

ix. Notifications

Zapfä can send push notifications. They’re entirely optional: turn them off anytime in iOS Settings → Notifications → Zapfä, or per-category inside the app.

x. Ending things

You can leave anytime. Delete your account from in-app Settings → Delete Account. Deletion is immediate and cascades through everything we hold for you — bottles, ratings, notes, wishlists, AI history, devices. (Your label photos were never stored with us to begin with — they live on your device.) The one exception is described in §v: wine data you promoted to the shared catalog stays, anonymized, with no remaining link to you. If you want a copy of your data first, the Privacy Policy explains how to request an export.

We can end accounts too — ones that violate these terms or that pose a risk to other users or the service. If we terminate your account for cause, we’ll tell you why. Any active subscription is billed through Apple, so refund handling follows Apple’s policies (§viii).

We can wind down the service. If Zapfä ever shuts down entirely, we’ll give you at least 30 days’ notice and a window to export your data before anything is deleted.

xi. Liability and warranty

Zapfä is provided “as is” and “as available,” without warranty of any kind, express or implied — including implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We work hard on uptime and data integrity, but we can’t guarantee the service will be uninterrupted or error-free, or that AI output will be accurate (§vi).

To the maximum extent allowed by law, our total liability to you is limited to the greater of US$50 or the amount you’ve paid us in the past twelve months, and we’re not liable for indirect, incidental, special, or consequential damages, or for loss of data, profits, or goodwill.

This doesn’t exclude or limit liability for things that can’t legally be excluded — gross negligence, willful misconduct, death or personal injury caused by our negligence, or fraud. If you live somewhere whose law doesn’t allow certain limitations above, those limitations apply to you only to the extent permitted.

xii. App Store terms

Because Zapfä is distributed through Apple’s App Store, Apple requires the following, and we both acknowledge it:

These terms are between you and Redwood Strategy Partners LLC (d/b/a Redwood Strategy Labs) only — not Apple. We, not Apple, are solely responsible for Zapfä and its content.
Scope of license: your license to use Zapfä is non-transferable and limited to Apple-branded devices that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions (with access for Family Sharing accounts where applicable).
Maintenance and support: we, not Apple, are responsible for any maintenance and support. Apple has no obligation whatsoever to provide maintenance or support for Zapfä.
Warranty: to the extent any warranty exists and isn’t disclaimed, we’re responsible for it. If Zapfä fails to conform to an applicable warranty, you may notify Apple, and Apple will refund the purchase price (if any) to you. To the maximum extent permitted by law, Apple has no other warranty obligation with respect to Zapfä.
Product claims: we, not Apple, are responsible for addressing any claims relating to Zapfä or your use of it — including product liability claims, claims that the app fails to meet legal or regulatory requirements, and claims under consumer protection or similar laws.
Intellectual property claims: if a third party claims Zapfä infringes their intellectual property rights, we, not Apple, are solely responsible for the investigation, defense, settlement, and discharge of that claim.
Legal compliance: you represent that you are not located in a country subject to a U.S. government embargo or designated by the U.S. government as a “terrorist supporting” country, and that you are not on any U.S. government list of prohibited or restricted parties.
Third-party terms: you must comply with applicable third-party terms when using Zapfä (for example, your wireless data agreement).
Apple as third-party beneficiary: Apple and its subsidiaries are third-party beneficiaries of these terms, and upon your acceptance, Apple has the right to enforce them against you.
Questions, complaints, or claims about the app go to: Redwood Strategy Labs (Redwood Strategy Partners LLC), 2108 N St STE N, Sacramento, CA 95816, United States — support@zapfae.com.

xiii. Changes to these terms

If we make material changes, we’ll give you at least 30 days’ notice — in the app and by email to active accounts — before the new terms take effect. Keep using Zapfä after that date and you’ve accepted them; if you don’t accept them, delete your account before they take effect and nothing new applies to you. Non-material changes (typos, clarifications, new feature descriptions that don’t change your rights) may take effect when posted, dated at the top of this page.

xiv. Governing law

These terms are governed by the laws of the State of California, USA, excluding its conflict-of-laws rules. Disputes that can’t be resolved by writing to support@zapfae.com first go to the state or federal courts located in Sacramento County, California. If you live in a jurisdiction whose mandatory consumer-protection laws apply to you (for example, the EU or Switzerland, if you’re using Zapfä from there), you keep the benefit of those protections and may bring proceedings in the courts of the country where you live. Nothing in these terms affects your statutory consumer rights.

xv. The boring-but-necessary bits

Severability: if a court finds any part of these terms unenforceable, the rest stays in force.
Entire agreement: these terms, together with the Privacy Policy and the subprocessor page it references, are the whole agreement between you and us about Zapfä.
No waiver: if we don’t enforce a provision today, we haven’t given up the right to enforce it tomorrow.
Assignment: you can’t transfer your account or these terms to someone else; we may assign them in connection with a merger, acquisition, or sale of the business — your rights under them travel along unchanged.
