Manga Craft — Privacy Policy

Effective 8 September 2026 · Version 1.0 · Oddly Effective LLC

Manga Craft is a voxel sandbox game published by Oddly Effective LLC. We built it to collect as little as we possibly can, and this page says exactly what it touches, why it touches it, who else sees it, and how long anyone keeps it.

We have written this in plain language rather than legal boilerplate, because a privacy policy nobody can read protects nobody. Where the law requires specific wording, that wording is included and marked.

If anything on this page does not match what the app actually does, this page is wrong and we want to hear about it: start@oddlyeffective.com

1. The short version

We do not ask who you are. There is no account, no sign-up, no email address, no password, no username. We cannot identify you and we do not try to.

The app talks to four outside services and no others:

• Apple or Google, to take a payment
• RevenueCat, to remember what you bought so we can unlock it again
• OneSignal, to send you a notification — only if you allow it
• Unity Gaming Services, to connect you to a friend — only if you choose to play together

Everything else — your worlds, your photographs, your progress, your settings — stays on your phone and is deleted when you delete the app.

There are no adverts. There is no analytics SDK. There is no chat. We do not sell or share your personal information, and we never have.

2. Who we are

Oddly Effective LLC is the data controller for the purposes of this policy.

We are a small studio. Privacy questions are read and answered by a person, not a ticketing robot, and we aim to reply within a few days and are required to within thirty.

3. What we never collect

This list is deliberately specific, because vague privacy policies hide things.

• No identity. No name, email address, phone number, postal address, password, username, date of birth or government identifier. The game never asks for any of them and has no field in which to type them.
• No location. We do not request location permission, do not read GPS, and do not perform IP geolocation ourselves. (RevenueCat and OneSignal derive a country from your IP address — see section 6. That is a country, not a location, and we cannot see a map.)
• No contacts, photos, files, microphone, camera, calendar, health or motion data. The app requests none of these permissions. If your phone ever asks you to grant one of them for Manga Craft, something is wrong and you should tell us.
• No advertising identifier. The IDFA on iOS and the Advertising ID on Android are never read. The App Tracking Transparency prompt is never shown, because we have nothing to ask for.
• No analytics SDK of any kind. There is no Firebase, no Google Analytics, no AppsFlyer, no Adjust, no Amplitude, no Mixpanel, no Unity Analytics, no attribution SDK. We do not know how many people opened the backpack screen and we have chosen not to find out.
• No chat, and no user-generated text at all. There is no text chat, no voice chat, no usernames, no comments and no profiles. Players who share a world communicate through a handful of small wordless gestures. There is nothing to moderate because there is nothing to type.
• No biometrics, no fingerprinting. We do not build a device fingerprint and do not attempt to recognise you across apps or installs.
• No sale of personal information, and no sharing for cross-context behavioural advertising, as those terms are defined under California law. We have never done this and have no plans to.

4. What stays on your device

All of the following is written into the app's own private storage on your phone. It is not transmitted to us, it is not backed up to our servers, and there is no cloud save. It is removed when you uninstall the app.

• Your worlds — the “Volumes” — including the terrain seed, every block you have placed or broken, and where you were standing when you last closed the game
• Your progress — inventory, level, experience, achievements, unlocked recipes, and your in-game currency balance
• Your settings — graphics quality, controls, audio volumes, field of view, and which once-only notes you have already seen
• The birth year you enter at the age gate. This is written to your device's local settings and is never transmitted anywhere, to us or to anyone else. Its only job is to keep the app from enabling anything age-restricted.
• Photographs you take in Photo Mode — saved as ordinary image files in the app's own folder. We never see them. If you want to share one, you share it yourself.

We have no ability to read any of this, and we cannot recover it for you if you lose it. That is the trade-off of a game that does not require an account.

5. What leaves your device, and to whom

Only four services ever receive anything, and two of the four only if you choose to switch that feature on.

Nothing else in the app makes a network request that carries information about you.

6. The complete data table

This is every piece of information that leaves the device, what it is for, who receives it, and whether it can identify you.

On IP addresses. An IP address is treated as personal data under EU law, so we name it here honestly rather than hiding it. It is used only to route packets between two players during a session you started, and it is handled by Unity's relay infrastructure. We never see it, never store it, and it is not retained after the session ends.

7. Purchases and subscriptions

Payments are handled entirely by Apple (App Store) or Google (Google Play) under their own privacy policies. We never see your card number, your billing address, your bank, or your legal name. We receive only a confirmation that a purchase succeeded.

To know which purchases and subscriptions to unlock for you, the app uses RevenueCat, a purchase-management service. RevenueCat receives:

• a random identifier the app generates for your installation, not linked to you
• your purchase and subscription receipts as issued by Apple or Google
• your device model, operating system version and app version
• a country derived from your IP address, so prices display in the right currency

RevenueCat does not receive your name, your email address or your payment details. Their privacy policy: revenuecat.com/privacy

Managing or cancelling a subscription is done through your Apple ID or your Google account, not through us. We cannot cancel a subscription on your behalf and we cannot issue a refund — those are the store's to give. Refund requests go to Apple or Google.

8. Notifications

Notifications are entirely optional. The game asks once; if you decline, nothing in this section ever happens, and the app works normally without them.

If you allow them, the app uses OneSignal to deliver them. OneSignal receives:

• a push token issued by Apple or Google — the address a notification is delivered to. It is meaningless outside the push system and is revoked the moment you turn notifications off.
• your device model and operating system version, so a notification renders correctly
• your language and timezone, so a message arrives at a reasonable hour in a language you read
• a country derived from your IP address

OneSignal does not receive your name or email address, because we do not have them to give.

You can turn notifications off at any time in your phone's settings, or in the game's own options. Doing so revokes the token and stops all of the above. OneSignal's privacy policy: onesignal.com/privacy_policy

9. Playing with a friend

Manga Craft can be played entirely alone, and is by default. Nothing in this section happens unless you deliberately host a world or join someone else's using a Story Code.

When you do, the app uses Unity Gaming Services — specifically Relay and Authentication — to connect the two devices. For the duration of that session:

• Unity Authentication issues an anonymous player ID: a randomly generated value tied to the installation, not to you. No email, no account, no sign-in.
• Unity Relay handles the IP addresses of both players in order to route the connection between them. This is how any online game works; there is no way to connect two devices without an address to send packets to.
• Game state — which blocks changed, where each player is standing, which gesture someone just made — passes between the two devices through that relay.

There is no chat, no voice, no usernames and no profiles. The only thing your friend learns about you is what you build.

None of this is retained by us after the session ends. We operate no game servers of our own and store no session records. Unity's policy: unity.com/legal/game-player-and-app-user-privacy-policy

A word of caution about Story Codes. A Story Code is a number that lets someone open the same world as you. It contains nothing about you, but anyone who has it can join. Share it only with people you actually want in your world, the same way you would treat the code to any private room.

10. Crash reports

If you have enabled “Share with App Developers” on iOS, or the equivalent usage-and-diagnostics setting on Android, Apple or Google may pass us anonymous crash logs. These contain the technical state of the app at the moment it failed — which function, which device, which OS version — and no personal information.

We use them for exactly one thing: fixing whatever crashed.

This is controlled entirely by your phone's settings, not by us. If it is off, we receive nothing.

11. Advertising

There are no adverts in Manga Craft. No banners, no interstitials, no rewarded video, no sponsored placements. No advertising SDK is compiled into the app, no advertising identifier is read, and no data is shared with any advertising network.

If that ever changes, it will not change quietly: this page will be updated before the version containing adverts is released, the effective date at the top will change, the store listings will be updated on the same day, and the app will tell you.

12. Children

Manga Craft is not directed at children under 13.

We know a blocky building game attracts younger players regardless of intent, so we have built the app so that there is nothing for a child to give away: no account, no chat, no profile, no advertising identifier, no analytics, and no way to type anything that reaches another person.

The age gate on first launch asks for a birth year. That year is written to your device's local settings and is never transmitted — not to us, not to any third party. Its only purpose is to let the app avoid enabling anything age-restricted.

We do not knowingly collect personal information from children under 13, in the sense of the United States Children's Online Privacy Protection Act (COPPA), nor from children under 16 in the sense of the GDPR. Since we do not collect personal information from anyone, there is nothing for us to have collected.

If you are a parent or guardian and you believe a child has somehow provided personal information to us, write to start@oddlyeffective.com and we will investigate and delete anything found. In practice, everything a child does in this game stays on the device they did it on, and uninstalling removes it.

13. How long anything is kept

We hold no personal database of our own. There is no customer list, because there are no customers we can name.

14. Security

We reduce risk mainly by not holding anything worth stealing. There is no user database to breach, because there are no user accounts.

Beyond that: all network traffic between the app and the services named here uses encryption in transit (TLS). The services we rely on — Apple, Google, RevenueCat, OneSignal, Unity — maintain their own security programmes, which you can read about in their policies linked in section 20.

No system is perfectly secure. If you find a vulnerability in Manga Craft, please tell us at start@oddlyeffective.com before telling anyone else, and we will work with you.

15. Your rights

Because we hold no personal information that identifies you, there is generally nothing for us to export, correct or delete on our side. In practical terms:

We will answer any privacy request within 30 days, and we will not charge you for it or treat you differently for having asked.

16. For people in the EEA, UK and Switzerland

Oddly Effective LLC is the controller of the limited data described in this policy.

Legal bases. Under the UK and EU General Data Protection Regulation we rely on:

Your rights under the GDPR are to access, rectify, erase, restrict, object, and to data portability, plus the right to withdraw consent at any time without affecting processing already carried out. Exercise any of them by emailing start@oddlyeffective.com.

We are honest that these rights have limited practical content here: we cannot produce a copy of “your data” because we hold none that identifies you. We will say so plainly rather than sending you an empty file.

Automated decision-making. There is none. No profiling, no scoring, no automated decision that produces legal or similarly significant effects.

Complaints. You have the right to complain to your local supervisory authority — in the UK, the Information Commissioner's Office (ico.org.uk); in the EEA, your national data protection authority. We would rather you told us first, but it is your right either way.

17. For people in California

Under the California Consumer Privacy Act as amended by the CPRA:

Categories of personal information collected in the last 12 months:

Sources: directly from your device, and from Apple or Google when a purchase completes.

Business purposes: delivering purchases, restoring them, sending notifications you asked for, connecting co-op sessions, and fixing crashes. Nothing else.

We do not sell personal information, and we do not share it for cross-context behavioural advertising. We never have. There is therefore no “Do Not Sell or Share My Personal Information” link, because there is nothing to opt out of. If that ever changes, we will add one before it does.

Your California rights are to know, delete, correct, opt out of sale or sharing, limit use of sensitive information, and not to be discriminated against for exercising any of them. Email start@oddlyeffective.com. We do not require an account to make a request, and we will not create one in order to verify you.

18. For people in other US states

Residents of Virginia, Colorado, Connecticut, Utah, Texas, Oregon, Montana and other states with comprehensive privacy laws have broadly similar rights to those described in sections 16 and 17 — to access, correct, delete, and to opt out of targeted advertising, sale, and profiling.

We do not conduct targeted advertising, do not sell personal information, and do not profile. Requests go to the same address: start@oddlyeffective.com.

19. International transfers

Oddly Effective LLC is based in the United States. The services named in section 20 process data in the United States and, in some cases, in other countries where they operate infrastructure.

If you are in the EEA, the UK or Switzerland, the limited technical data described in this policy is transferred to the United States. Where a transfer requires a safeguard, our processors rely on the European Commission's Standard Contractual Clauses and the UK International Data Transfer Addendum, and several participate in the EU-US Data Privacy Framework. The current position for each is stated in that processor's own policy, linked below.

20. Our sub-processors

The complete list. If one is added, this page is updated before the version that adds it ships.

That is the whole list. There is no sixth entry.

21. Changes to this policy

If a future version of Manga Craft collects something not described here, this page will be updated before that version is released, and the effective date and version number at the top will change.

Where a change is significant — a new category of data, a new processor, or advertising — we will additionally tell you inside the app, and where the law requires it, ask you first.

We will not make a change quietly and hope you do not notice. If you ever find that the app does something this page does not describe, that is a mistake on our part and we want to be told.
