Privacy Policy

Effective Date: September 30, 2026

Company: Stillware Ltd

Stillware Ltd ("we", "our", or "us") builds software you own. We believe that your private data—whether it is financial ledgers, personal journals, home inventories, or health records—belongs exclusively to you.

This Privacy Policy explains our strict, privacy-first approach to information across all Stillware Ltd applications (including Zeroed and all future releases).

Core Principle: Local-First & Zero Telemetry

All Stillware applications are built on a "local-first" architecture. The data you create inside our apps is stored directly on your physical device. We do not have servers that host, process, or read your personal app data, and we utilize zero telemetry or behavioral tracking.

1. Information Collection and Use

Your Application Data

Whatever data you input into a Stillware app (e.g., transactions, text entries, photos, audio logs) is encrypted and saved strictly to your local device storage. We do not collect, transmit, or have access to this data.

Data Synchronization (Your Cloud, Your Rules)

Many Stillware apps offer cross-device synchronization using your personal cloud storage (such as Google Drive or Apple iCloud).

  • How it works: Our apps communicate directly with your personal cloud provider to sync an encrypted backup of your local database.
  • Our Access: We request the strictest, most limited permissions available (e.g., the drive.file scope on Google Drive). This means our apps can only access the specific sync folders they create. We cannot view, edit, or delete any other files in your personal cloud.
  • Your Control: You retain ultimate ownership. You can revoke the app's access or delete the sync folders from your personal cloud at any time.

On-Device Processing

Some of our apps utilize Machine Learning (like receipt scanning, OCR text extraction, or image filtering). All processing happens locally on your device's hardware. No images, text, or audio are ever sent to our servers for processing.

Purchases, Licence Activation and Free Trials

Direct downloads (Windows and Mac) are sold through Paddle, which acts as Merchant of Record: Paddle collects your payment and billing details and is responsible for them under its own privacy policy. When a purchase completes, Paddle tells our licence service the transaction reference. The service creates a licence key and emails it to the address you gave Paddle, using Resend to deliver the message. We use your email address only for that one message and do not store it in our licence records.

Our licence records hold a one-way hash of your licence key, the Paddle transaction reference, the product, and for each device you activate a device identifier generated by the app and the activation dates. They do not hold your name, your email address, the name of your device, or anything you enter into an app. To stop a free trial restarting when an app is reinstalled, the trial service also records a device identifier and the date the trial began. These records let us limit a licence to a set number of devices, let you move it to a new one, and keep trials fair.

Website & Blog Analytics

The stillwareltd.com website uses Umami Cloud, a cookieless analytics service, to count visits and to measure which pages lead to an app-store listing or download. It sets no cookies in your browser. It receives the page you viewed, the page that referred you, your browser, operating system, screen size and language, an approximate location such as your country, and events such as clicking an app-store link or playing an embedded video. Umami states that it does not collect personally identifiable information and that visitors cannot be identified or tracked across websites. We use the data only for aggregate reporting. If your browser sends a Do Not Track signal, the tracker sends nothing, and you can also block it with your browser's tracking protection or an extension. None of this applies to our apps, which contain no analytics or telemetry (see above). We do not use Meta Pixels, Google Analytics or advertising trackers on the website.

Support Communications

When you contact us for technical support, we receive your email address and any information you voluntarily provide in your message. We use this information exclusively to assist you and resolve your issue.

2. Website Communications & Newsletters ("Join the Rebellion")

We offer voluntary email subscriptions on our website (stillwareltd.com) so you can be notified when we launch new apps, publish new blog posts, or release major updates.

  • What we collect: If you choose to subscribe to our newsletter, ask to be notified about an upcoming app (such as a waitlist), or request a free download such as a printable sheet or puzzle pack, we collect only the email address you provide. Our website forms are processed and stored by our host, Netlify (Netlify Forms).
  • How we use it: We use this email address strictly to send you the specific communications you requested, including the file itself when you ask for a free download. We do not track your email open rates with invisible pixels, and we do not profile your reading habits.
  • Our Promise: We will never sell, rent, or trade your email address to third-party marketers, data brokers, or advertisers.
  • Your Control: You can opt-out and unsubscribe from these emails at any time by clicking the "Unsubscribe" link at the bottom of any email we send you, or by contacting support. Upon unsubscribing, your email is permanently removed from our active mailing list.
  • Separation of Data: Your newsletter subscription is managed entirely separately from our applications. Subscribing to our website does not link your email address to your encrypted, local app data.

3. Third-Party Services

Because we do not host your data, our use of third-party services is strictly limited to facilitating purchases and app functionality:

  • Payment Processors (Paddle, Apple App Store, Google Play): These services process your payments and act as the Merchant of Record. We do not collect or store your credit card details.
  • Resend: Our email delivery provider, which sends your licence key email. It keeps delivery records of that message under its own privacy policy.
  • Netlify and Turso: Netlify hosts this website and the licence service, and Turso hosts the database that holds the licence and trial records described above.
  • RevenueCat: We use RevenueCat to manage purchase histories and validate lifetime licenses across devices. They may collect anonymous App User IDs and anonymous purchase receipts, but this is never linked to your actual app data.
  • Cloud APIs (Google Drive / Apple iCloud): Used solely to route your encrypted data between your own devices.

YouTube API Services

Stillware Ltd publishes budgeting and chess videos on its own YouTube channels, Zeroed: Offline Budget Planner and RankUp Chess. To do this we operate an internal publishing tool that uses YouTube API Services to upload videos, thumbnails, subtitles and playlist entries to those channels, and to read public YouTube data (video titles, view counts and search results) when planning new videos. By using or interacting with our YouTube channel you are also bound by the YouTube Terms of Service, and Google's handling of your data is described in the Google Privacy Policy.

  • No viewer data is collected. The tool authenticates only our own channel's Google account. It does not access, collect or store any data about YouTube users, viewers, subscribers or commenters, and it does not read private data from any account other than our own.
  • What is stored: the channel's OAuth access token (on a single company computer, never on a server), the identifiers of the videos we uploaded, and aggregate public statistics about videos (view counts, like counts, durations) retained for no longer than 30 days for editorial planning. No personal information is stored.
  • No sharing: nothing obtained through YouTube API Services is sold, shared with third parties, or used for advertising.
  • Revoking access: the channel owner can revoke the tool's access at any time from the Google security settings page. Anyone who believes we hold data about them obtained through YouTube API Services may contact support@stillwareltd.com and it will be deleted within 30 days.

4. Data Retention and Deletion

Because Stillware Ltd does not host user accounts or store your app data on our servers, we cannot "delete your account" in the traditional cloud-software sense: there is no account and no app data to delete. The only records we hold are the small licence and trial records described in section 1 (no name or email). If you want a licence record removed, email support@stillwareltd.com with your Paddle receipt reference. Removing it ends that licence, so we will confirm with you first. Purchase records held by Paddle, Apple and Google are governed by their own policies.

To completely and permanently destroy your data:

  1. Delete the specific Stillware application(s) from your device(s).
  2. Log in to your personal cloud provider (Google Drive, iCloud) and delete the app-specific data folder (e.g., ZeroedData).

5. Security

  • Local Encryption: Where applicable, your databases are encrypted on-device using industry-standard protocols (such as AES-256) before they are ever synced to your personal cloud.
  • Transit Security: All communication between your device and your cloud provider, or your device and our payment processors, occurs over secure HTTPS (SSL/TLS) connections.

6. Children's Privacy

While Stillware Ltd designs some offline-native applications specifically intended to be safe, secure sandboxes for pre-teens and teenagers, we do not collect personal information from children. Because our apps operate entirely offline and do not transmit user data to our servers, there is no mechanism for us to collect, store, or share data from minors.

7. Beta Testing & Feedback

If you participate in a Stillware Beta Exchange, we may collect your email address, device OS, and written feedback to improve the product and grant you a lifetime software license.

Your email and feedback are never linked to your in-app data.

You may request the deletion of your beta feedback or email from our contact records at any time by emailing support.

8. Changes to This Policy

As we release new applications, we may update this Privacy Policy. We will notify users of any material changes by posting the new version on this page and updating the "Effective Date." Because we do not require user accounts, checking this page is the best way to stay informed.
