Zydeno · Pipkettle for Android

Terms of Use

The rules for using Pipkettle: what the app is and is not, how its random results work, what you are responsible for, and the limits of our responsibility.

Effective: 2026-10-22 Last updated: 2026-10-22 Version 1.0 Android app

At a glance

A tool for the table

Dice, coins, wheels, teams, initiative and cards for tabletop play and everyday choices, for entertainment.

Not for gambling or prize draws

Do not use results for bets, lotteries, raffles, giveaways or any decision with money or legal effect.

Your data is yours to keep

Everything stays on your phone; we hold no copy. Export a backup if your saved table matters to you.

Provided “as is”

We work hard on fairness and reliability, but the app comes without warranties, within the limits the law allows.

Free in the current version

No ads or purchases today. Future versions may add ads or optional paid features; you pay only if you choose to buy through Google Play.

1Provider and scope

These Terms govern the Android app Pipkettle, provided by Zydeno. Contact [email protected] with any question about them. The Privacy Policy explains what stays on your device, what you can export and how support e-mails are handled.

2Agreement to these terms

These Terms of Use (“Terms”) are a legal agreement between you and Zydeno, the developer of Pipkettle (“we”, “us”). They apply to the Pipkettle app for Android, its updates and everything it shows or produces (together, “the app”). By installing, opening or using the app you accept these Terms. If you do not accept them, do not use the app and uninstall it.

The Privacy Policy explains how the app handles data and forms part of these Terms. If we offer optional features under additional terms in the future, for example paid features, those terms will be shown to you before you accept them and will apply together with these Terms.

You must be old enough to enter into a binding contract where you live, or use the app with the consent and supervision of a parent or guardian who accepts these Terms for you. If you use the app for an organisation, you confirm that you may accept these Terms on its behalf; the consumer-protection provisions of these Terms apply only to consumers.

3The app

Pipkettle is an offline tool for tabletop sessions and everyday choices. It rolls standard and custom dice (including dice notation, keep and drop, rerolls and modifiers), flips a coin or neutral token, spins decision wheels with visible weights, splits a group into teams, keeps initiative order, draws from standard or custom decks, and records results in a table receipt and a local journal. It also shows exact probability previews and statistical checks of its random generator.

The app is an entertainment and utility tool. It is not a game of chance with stakes, does not award prizes, points, currency or anything of value, and has no multiplayer service, chat, leaderboard or online content.

4Not professional advice; no safety-critical use

Check results before you rely on them

The random results, probability previews, fairness checks, team splits, initiative orders and receipts that Pipkettle shows are produced from models, published methods and data and the values you enter, and they can be wrong. Before relying on them for bets or wagers, lotteries, raffles, giveaways or prize draws, allocating money or things of value, or any selection with legal, contractual, financial, employment or official effect, remember that the app is not designed or permitted for that use and rely instead on a process that is lawful, documented and, where required, licensed or approved for that purpose.

The app is a tool to help you plan and calculate. It does not give professional, engineering, legal or other expert advice, and using it does not create a professional relationship with us. You remain responsible for your inputs, for how you interpret the results and for what you decide to do.

Do not use the app as the only basis for a decision where an error could cause death, personal injury, damage to property or the environment, or legal or financial loss, and do not use it in a safety-critical system, in an emergency or to control equipment. Pipkettle is not a gambling, lottery or certified random-number service, and its fairness checks are statistical diagnostics, not a certification or audit.

5Licence to use the app

Subject to these Terms, we grant you a limited, personal, revocable, non-exclusive, non-transferable and non-sublicensable licence to download, install and use the app on Android devices you own or control, for your own purposes (personal tabletop play, everyday choices and entertainment). The app is licensed to you, not sold.

Except where these Terms, an open-source licence or mandatory law allow it (for example decompiling for interoperability where the law permits), you may not: copy, modify, translate or create derivative works of the app; decompile, disassemble or reverse-engineer it; rent, lend, sell, sublicense, distribute or publish it, or make it available for use by others over a network; remove or change any copyright, trademark or legal notice; or get around any technical limit of the app, including any future purchase, licence or advertising mechanism.

Open-source components and fonts in the app are licensed under their own licences, listed in the app under About → Open-source licenses. Those licences prevail for those components, and nothing in these Terms limits the rights they give you.

6Random results and fairness

Each result is chosen by Android’s cryptographic random-number generator on your device, using a method designed so that every face, option or card has its stated chance. The dice motion, coin flip, wheel spin and card animation present that result; they do not decide it. You can show any result instantly instead of animated.

Probability previews are calculated from the expression you enter, and the fairness view shows statistical tests of the generator on your device. These are diagnostics. They are not a certification, an audit, a guarantee that any sequence of results is suitable for a particular purpose, or a promise that results will meet anyone’s expectations. Streaks and repeats occur naturally in random results. Results depend on the expression, options, weights and settings you enter; check them before you roll.

7No gambling, wagers or prize draws

For play and everyday choices only

Do not use Pipkettle, or its results, to place or settle bets or wagers, to run or decide a lottery, raffle, sweepstake, giveaway, contest or prize draw, to allocate money, goods or other things of value, or for any selection that has legal, contractual, financial, employment, medical or official effect.

Such activities are regulated in many countries and often require a licensed, audited or legally approved random process. Pipkettle is none of these. The app has no stakes, chips, balances, payouts, jackpots or rewards, and we do not offer, support or link to gambling services. If you nevertheless use the app in breach of this section, you do so entirely at your own risk and are solely responsible for complying with the law.

8Comfortable and responsible use

You are responsible for the expressions, options, weights, names and rules you enter, for how your group agrees to use the results, and for settling any disagreement at your table. A result shown by the app does not decide a dispute on its own.

Choose comfortable motion, sound, haptic and screen settings. Use shake-to-act only where a sudden movement of the phone is safe, hold the phone securely and do not shake it near people, drinks or fragile objects. Do not use the app while driving or doing anything that needs your full attention. The keep-screen-on option uses more battery; it switches off after a period of inactivity and when you leave the table.

9Your data, exports and deletion

Your saved sets, people, rounds, decks, journal and settings are stored only on your device. We hold no copy and cannot restore lost data. Android automatic backup and device transfer are switched off, so uninstalling the app, clearing its storage, resetting or losing your phone erases the data unless you have exported a backup. Use Settings → Your data to export a complete backup, to import one (with a preview and a choice to add to or replace your current data) and to delete all data.

Replacing data overwrites what is on the device; export a copy first. The app checks archives and writes changes atomically, but it cannot guarantee recovery after a device or storage failure. Backups and CSV files are not encrypted by the app. If you choose a cloud-backed location or share a receipt with another app, that provider or app is responsible for it under its own terms. Deleting data in the app does not delete exported files or text you have shared.

10Content you add

You can add your own text (names, labels, wheel options, card texts, macros) and your own images for custom faces. You keep any rights you have in this content. You confirm that you have the right to use it; you grant us no rights in it, because it never leaves your device through the app. Do not add images, logos, characters or texts that you are not allowed to use, and do not record or share other people’s names without their agreement. Before sharing a receipt, check the preview; participant names are included only if you switch them on.

11Third-party software and original content

The app uses AndroidX, Jetpack Compose, Kotlin, kotlinx.coroutines and kotlinx.serialization under the Apache License 2.0, and bundles the Sofia Sans typeface under the SIL Open Font License 1.1 (Copyright 2019 The Sofia Sans Project Authors). Licence texts and copyright notices are available offline in Settings → About → Open-source licenses. Where an open-source licence gives you rights that differ from these Terms, the open-source licence prevails for that component.

The dice, coin, wheel and card artwork, the icon, the table receipt and the in-app explanations of dice notation are created for Pipkettle. Generic dice notation and probability methods are common knowledge and are not claimed as our exclusive property. No third-party game rules, game texts, characters, logos or artwork are licensed or bundled, and the app is not affiliated with, or endorsed by, any publisher of tabletop games. Android, Google Play, your browser, e-mail app, speech engine and any document provider are independent products and services with their own terms; they are named only to explain how the app works.

12Acceptable use

Use the app lawfully and in line with these Terms, including §7. Import only files you trust and have the right to use. Do not present results, receipts or fairness checks as an official, certified or independently audited draw, or as evidence that a selection was fair for a legal, commercial or regulated purpose.

You also agree not to:

  • use the app, or data obtained through it, in a way that is unlawful, fraudulent or harmful, or that infringes anyone’s intellectual property, privacy or other rights;
  • enter, store or pass on other people’s personal data with the app unless you are allowed to do so;
  • interfere with or disrupt the app or any service it connects to, introduce malicious code, or try to gain unauthorised access to any system;
  • use automated means to extract data from the app or from the services it uses beyond normal personal use;
  • present the app or its output as official, certified or endorsed by any authority, manufacturer or data provider.

13Intellectual property

The app’s original code, design, artwork and texts are protected by intellectual-property law and belong to us or our licensors. Exporting a backup or receipt gives you a copy of your own data; it does not transfer rights in the app’s software, artwork or fonts.

The names Zydeno and Pipkettle and their logos are our marks. You may refer to them to describe the app accurately, but not use them in a way that suggests endorsement. Names of third parties appear only to identify data sources, file formats, standards or rules; they belong to their owners and do not imply endorsement. If you send us feedback or ideas, we may use them without any obligation to you. We claim no rights in your own projects, data or exported files.

14Price, payments, ads and future paid features

Current version. The current version of Pipkettle is provided free of charge, without ads and without in-app purchases or subscriptions. This describes the current version only. It is not a promise that the app, or any feature of it, will remain free of charge or free of ads.

Possible changes. We may at any time introduce advertising; offer paid features, in-app purchases, subscriptions or a paid edition; change which features are free; and set or change prices. Features that are free today may require payment in a future version. We will describe such changes in the store listing and release notes, and in the Privacy Policy where they affect data.

Purchases. Any purchase will be made through Google Play and processed by Google under the Google Play Terms of Service and its payment policies. Prices are shown in Google Play before you buy, including taxes where applicable. Subscriptions renew automatically until you cancel them in Google Play; cancelling stops future renewals. Refunds follow Google Play’s refund policies and your mandatory consumer rights, such as the right of withdrawal in the EU and the UK. Where you ask for immediate access to digital content during a withdrawal period, you may lose that right to the extent the law allows, and you will be asked to confirm this before you buy. You are charged only if you choose to buy something.

Ads. If the app shows ads, they are supplied by third parties. We are not responsible for the content of ads or for the products and services advertised, and any dealings with advertisers are between you and them.

Price changes. We may change prices for future purchases at any time. For an active subscription, we will announce a price increase as Google Play and the law require, and you can cancel before it applies.

15Disclaimer of warranties

The app, its random results, probability previews, fairness checks, animations, receipts, journal, backups and other functions are provided “as is” and “as available”. We do not warrant any particular distribution, sequence or outcome of results beyond what is stated in §6, error-free calculations, uninterrupted operation, compatibility with every device or the preservation of data stored on your device.

In particular, and to the maximum extent permitted by law, we do not warrant that the app will meet your requirements, run without interruption, be compatible with your device or be free of errors or harmful components; that defects will be corrected; that data from third-party sources is accurate, complete or current; or that any feature, data source or price will remain available or unchanged.

Nothing in these Terms excludes or limits warranties, guarantees or conformity rights that cannot be excluded under the law that applies to you as a consumer (§17).

16Limitation of liability

To the extent permitted by law, we are not liable for any loss arising from a result shown by the app or from a decision you or others make based on it, including bets, prize draws, allocations or disputes in breach of §7; for lost, corrupted or overwritten data or backups; for injury or damage caused by shaking or dropping your phone; or for interruption of play.

Cap. To the maximum extent permitted by law, our total liability for all claims arising out of or relating to the app or these Terms is limited to the greater of (a) the total amount you paid us for the app and in-app purchases in the 12 months before the event giving rise to the claim and (b) 50 euros or the equivalent in your local currency. For the current version, which is free of charge, you have paid nothing.

These limits apply whatever the legal basis of the claim (contract, tort including negligence, strict liability or otherwise), even if a limited remedy fails of its essential purpose. They are part of the basis on which we make the app available.

What we do not limit. Nothing in these Terms excludes or limits liability for death or personal injury caused by our negligence; for fraud or fraudulent misrepresentation; for damage caused intentionally or by gross negligence; under mandatory product-liability law (including, where it applies, Directive (EU) 2024/2853 on liability for defective products and the UK Consumer Protection Act 1987); or any other liability that cannot be excluded or limited by law. Where the law allows only a partial limitation, our liability is limited to the extent it permits.

17Your rights as a consumer

If you use the app as a consumer, you benefit from the mandatory consumer-protection rules of the country where you live, and nothing in these Terms affects them. In particular:

  • EU and EEA: your statutory rights, including those on the conformity of digital content and digital services under the national rules implementing Directive (EU) 2019/770 where they apply, and mandatory product-liability rules, remain unaffected.
  • United Kingdom: your statutory rights, including under the Consumer Rights Act 2015, remain unaffected.
  • Australia: our services come with guarantees that cannot be excluded under the Australian Consumer Law. Where the law allows us to limit our liability for failing to meet a consumer guarantee for services that are not of a kind ordinarily acquired for personal, domestic or household use, our liability is limited to supplying the services again or paying the cost of having them supplied again.
  • New Zealand: if you acquire the app for business purposes, you agree that the Consumer Guarantees Act 1993 does not apply, to the extent the law permits.
  • United States and Canada: some states and provinces do not allow the exclusion of implied warranties or the limitation of incidental or consequential damages, so some of the exclusions above may not apply to you. In Québec, the mandatory provisions of the Consumer Protection Act apply.

18Indemnity

To the extent permitted by law, you agree to indemnify and hold harmless the developer against claims, liabilities, damages, losses and reasonable costs, including reasonable legal fees, brought by third parties and arising out of (a) your use of the app’s results, including any bet, prize draw or allocation in breach of these Terms, and the names, images and other content you add, export or share, (b) your breach of these Terms, (c) your violation of any law or of the rights of others, or (d) output of the app that you provide to another person, such as a client or employer. This does not apply to the extent a claim is caused by our own breach of these Terms or our negligence, or where local consumer law does not allow it.

19Changes, availability and termination

To the extent the law allows, we may change, update, add or remove features, change data sources, and suspend or discontinue the app, in whole or in part or in any country, at any time. We are not obliged to provide updates, maintenance or support, except where mandatory consumer law requires updates to keep the app in conformity.

You may stop using the app at any time by uninstalling it. Your licence ends automatically if you materially breach these Terms, and we may end or suspend it where the law requires. When it ends, you must stop using the app and uninstall it. Your data stays on your device under your control, so export what you need first.

Provisions that by their nature should continue after these Terms end continue to apply, including those on intellectual property, disclaimers, limitation of liability, indemnity, governing law and general provisions.

20Google Play

You obtain the app through Google Play. Your download, and any purchase you make, is also governed by the Google Play Terms of Service and Google’s policies. Where these Terms conflict with Google Play’s terms on the distribution, billing, refunds or licensing of apps obtained from Google Play, Google Play’s terms prevail to the extent of that conflict.

These Terms are between you and the developer only, not Google. Google is not responsible for the app or its content and has no obligation to provide maintenance or support for it. Android and Google Play are trademarks of Google LLC.

21Governing law and disputes

These Terms, and any dispute or claim arising out of or in connection with them or the app, including non-contractual disputes, are governed by the law of the country in which the developer is established, without regard to its conflict-of-laws rules. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

The courts competent for the place where the developer is established have jurisdiction. If you are a consumer, you keep the protection of the mandatory provisions of the law of your country of residence, and you may bring proceedings in the courts of that country where that law allows it.

Before starting formal proceedings, please write to [email protected] and give us at least 30 days to try to resolve the issue informally. This does not affect any time limit that applies to you by law or your right to use an alternative dispute-resolution body available to consumers in your country.

22General provisions

  • Entire agreement. These Terms, the Privacy Policy and any additional terms you accept for optional features are the entire agreement between you and us about the app.
  • Severability. If a provision is found invalid or unenforceable, it applies to the maximum extent permitted and the rest remains in effect.
  • No waiver. Not enforcing a provision is not a waiver of the right to enforce it later.
  • Assignment. You may not transfer your rights or obligations under these Terms. We may transfer ours, for example together with the app to another developer; where the law requires, this will not reduce your rights as a consumer.
  • Events beyond our control. We are not responsible for failure or delay caused by events beyond our reasonable control, such as outages of networks, devices or third-party services, natural disasters or acts of authorities.
  • Export and sanctions. You agree to use the app in compliance with applicable export-control and sanctions laws.
  • No third-party rights. No one other than you and us may enforce these Terms.
  • Notices. We may give notices in the app, in its store listing or release notes, or on this page. You can send notices to [email protected].
  • Language. These Terms are written in English, which is the binding version. A translation, if offered, is for convenience only, unless the law of your country requires otherwise.

23Changes to these terms

We may update these Terms, for example when we change the app, introduce ads or paid features (§14), or when the law changes. The effective date and version at the top of this page show which version applies, and the version history (§24) summarises the changes.

For material changes we give reasonable notice before they take effect, for example in the release notes or in the app. If you keep using the app after the changes take effect, you accept the updated Terms; if you do not agree, stop using the app and uninstall it. Changes do not apply to disputes that arose before they took effect.
