The short version

Who is behind the app

LITrenders is the trading name of Bruno Camargo, an independent developer. There is no company behind it and no team — one person builds these apps, and the same person reads the mail sent to litrenders@gmail.com.

Whenever this policy says “we”, it means exactly that one person.

What we collect

Nothing.

Budget Calendar has no accounts, no sign-up, no login, and no servers. We do not receive your budget, your expenses, your currencies, or any identifier for you or your device. We operate no server, so we have no way to know that you have installed the app, let alone what you put in it.

That is a statement about us. What Google collects through the banner is a different question, and a fair one to ask — the advertising section answers it.

What the app stores, and where

Everything you enter — your budget, date range, expense entries, currency choices and any exchange rate you set yourself — is stored only in the app's own private storage on your device. It never leaves the device except in the two ways you control:

• Android Backup. If you have Google's backup enabled in your Android settings, your app data is included in that backup so it can be restored to a new phone. That backup is between you and Google under Google's terms; we never see it and have no access to it.
• Export. You can export your data to a JSON file yourself. Where that file goes, and who you share it with, is entirely up to you.

Uninstalling the app deletes its data from the device.

Advertising in the Android app

This section describes the Android app. The web version is covered below.

The app displays a single banner advertisement, fixed at the bottom of the screen, served by Google AdMob. There are no other ads: no full-screen ads, no ads between screens, no video, and nothing that appears on launch.

What Google collects through it

Google's advertising library collects and shares the following automatically, for advertising, analytics and fraud prevention:

• your device's advertising ID and app set ID
• your IP address, from which an approximate location — roughly, the region or city — can be estimated
• interactions with the app, such as launches and taps
• diagnostic information about how the app and the library are performing

We never see any of it. It goes to Google, not to us, and Google's use of it is governed by their own policies at policies.google.com/technologies/partner-sites.

What the ads cannot see

Your budget, your date range, your expense entries, your currencies and your manual exchange rates. None of it is readable by the advertising code: your data lives in the app's own private storage, and the banner runs in a separate part of the app with no access to it. No figure you type is ever sent anywhere, to Google or to anyone else.

Your choice

If you are in the European Economic Area, the United Kingdom or Switzerland, the app shows you Google's consent form the first time you open it, before it requests a single ad, and you can decline personalised advertising there. You can change your answer at any time afterwards from the Ad privacy button in the app's settings row.

Wherever you are, you can also reset or delete your advertising ID from your phone's own settings, under Settings → Privacy → Ads (the exact path varies by manufacturer).

The web version

Besides the Android app, Budget Calendar also runs in a browser at litrenders.com/apps/budget-calendar/app.html. It is the same interface, and the same rule applies to your figures: your budget, date range, expense entries and currency choices are stored in your browser’s own local storage and are never sent to us or to anyone else. There is no account and no server.

Two things differ from the Android app, and both are about what the page itself loads.

Advertising on the web version

The full-screen web version carries advertising supplied by Google AdSense. There is no advertising anywhere else on litrenders.com — not on the home page, not on the app’s own information page, and not in the preview embedded there. It appears only when you open the app as a page of its own.

AdSense is Google’s advertising system for websites, and it works through the browser rather than through a device advertising ID. To select and measure ads, Google collects:

• cookies and similar browser storage set by Google on its own domains
• your IP address, from which an approximate location — roughly, the region or city — can be estimated
• the page being viewed and your interactions with the advertisement
• browser and device characteristics such as screen size and user agent

We never see any of it. It goes to Google, not to us, and Google’s use of it is governed by their own policies at policies.google.com/technologies/partner-sites.

What the ads cannot see

Your budget, your date range, your expense entries, your currencies and your manual exchange rates. The advertising code cannot read them: your data sits in this site’s own local storage, which is not readable from Google’s domains, and no figure you type is ever transmitted — to Google or to anyone else.

Your choice

If you are in the European Economic Area, the United Kingdom or Switzerland, Google’s consent message appears before any personalised advertising is requested, and you can decline there. Wherever you are, you can review and switch off personalised advertising for your Google account at myadcenter.google.com, and you can block or clear advertising cookies in your browser’s own settings. Blocking them does not affect any budgeting feature: the app works exactly the same with the advertising blocked.

What the web version does not do

There is no analytics on it, no crash reporting, no social login, no tracking pixel and no account. The fonts, styles and scripts that make up the interface are served from litrenders.com itself. Apart from the advertising described here, the only outbound request the page makes is the exchange-rate lookup described below.

The website privacy notice covers the rest of litrenders.com, which sets no cookies at all.

Exchange rates

To keep converted amounts current, the app periodically requests exchange rates from open.er-api.com, a public exchange-rate service operated by a third party.

What that request contains:

• the currency code being looked up, for example USD
• nothing else — no budget figures, no expense entries, no account, no advertising ID

As with any internet request, the service will see the IP address the request comes from. That is inherent to how the internet works, is not something the app sends deliberately, and is not something we receive. We operate no server and never see the request at all.

The lookup happens at most twice a day, and the result is cached on your device. If the request fails, or you are offline, the app falls back to a rate table bundled inside it and clearly labels the figure as an offline copy with the date it was captured. Every budgeting feature of the app works with no network connection — only the banner and the rate refresh need one.

You can also set an exchange rate by hand, in which case no lookup is used for that currency pair.

Permissions

Budget Calendar declares one Android permission itself:

• INTERNET — used to refresh exchange rates and to load the banner.

Google's advertising library adds two more when the app is built, which is standard for any app that shows ads:

• ACCESS_NETWORK_STATE — to check whether the device is online.
• AD_ID — for the advertising ID described above.

There are no others — no contacts, no location, no storage, no camera, no microphone.

Third parties

One: Google — as the supplier of the banner advertisement and its consent form in the Android app (AdMob), and of the advertising on the web version (AdSense). Both are described above. The exchange-rate service receives a currency code and nothing about you. There is no analytics library, no crash reporting, no social login, and no fonts or scripts loaded from the internet into the app's own interface.

Google Play Data safety summary

This covers the Android app: it is the same declaration made in the Play Console, restated here so that nothing is hidden behind a summary. Everything marked collected is collected by Google through the advertising banner, never by us.

Data collected through the banner is handled under Google's policies, not ours, and is never passed back to us in any form. The currency-rate request is a call for public reference data, not a transmission of your information.

Your data and how to remove it

• Delete an entry: delete it in the app.
• Delete everything: uninstall the app, or use Android's Settings → Apps → Budget Calendar → Storage → Clear data.
• Backups: if you have Android's own backup service enabled for the app, a copy may be held in your Google account under Google's terms, not ours. You control that in your device settings.
• Advertising data: held by Google, not by us. Change your consent from the Ad privacy button in the app, and reset or delete the advertising ID in your phone's settings.

Because nothing is held on our side, a deletion request has nothing to act on — but if you want that confirmed in writing, ask at litrenders@gmail.com.

Children

Budget Calendar is not directed at children and is not distributed to an audience under 13. We collect no data from anyone, including children. If you believe a child has provided personal information through the app, write to litrenders@gmail.com and it will be deleted.

Security

No app can promise perfect security, and this one does not. What it can do is keep the amount of data worth attacking as close to zero as possible, which is the approach taken here: data that never leaves your device cannot be leaked from a server, because there is no server holding it.

Traffic to any third-party service listed above is sent over an encrypted connection (HTTPS/TLS).

Changes to this policy

If a future version of the app collects or shares something it does not collect today, this page is updated before that version reaches Google Play, and the “last updated” date at the top changes with it. Material changes are also described in the release notes of the version that introduces them.

The current version of this policy always lives at this URL, which is the address given in the app's Google Play listing.
