Privacy Policy

Tony Crayfish Evolution

Effective November 9, 2026. Tony Crayfish Evolution for Mac, iPhone and iPad performs all ecosystem simulation, genetic calculations, challenges and batch experiments locally on your device. No remote computing service is used to run simulations. No account is required.

The app does not include advertising, third-party analytics or tracking services, and does not collect or transmit your simulation activity to Tony Crayfish Productions. Its genomes and creatures are simulated; the app does not request or analyze personal DNA, genetic test results or medical information.

The app stores settings, organism presets, high scores, experiment results and recovery data on your device. You can also save and open pond files and export reports using system file controls. Exports can include simulated genomes, ancestry, settings and user-entered names, as well as the simulation results. Please review a file before sharing it.

You choose where exported files are stored and with whom they are shared. If you choose iCloud Drive or another storage provider, that provider handles the files according to its own terms and your settings. This is separate from the local simulation: the app does not operate a cloud simulation service or automatically upload ponds to Tony Crayfish Productions.

You can delete exported files through Finder or Files and remove user presets through the app. Deleting the app on iPhone or iPad removes its local app data, but not files saved elsewhere; device backups may retain or restore data according to your Apple settings. On Mac, removing the app may leave saved data and preferences in its application container. Contact support for help removing these files.

If you choose to send a saved pond, report, screenshot or other information to support, we use the information you provide to investigate and respond. You may request deletion of support correspondence at [email protected]. Optional website and email links open external services. Apple may separately handle App Store, TestFlight and diagnostic information according to its own privacy terms and your sharing settings.

Tony Crayfish BioMatch

Tony Crayfish BioMatch runs its puzzle game on your device. It stores your campaign progress, board state, best times, hint counts and music/sound preferences locally so you can resume and compare your own runs. The app does not require an account and does not include advertising, analytics or tracking services. It does not send game activity, saved research or best times to a server operated by Tony Crayfish Productions.

The app does not request access to your photos, contacts, location, camera, microphone, health information or genetic data. Its biological experiments are fictional puzzle mechanics; it does not analyze personal biological or medical information.

Saved games and best times are separate on each device. Starting a new campaign replaces the saved campaign but keeps completed records. Deleting the iPhone or iPad app removes its local data; restoring a device backup may restore that data according to your Apple backup settings. On Mac, deleting the app may leave its local saved games and preferences in its sandbox container. Contact support if you need help removing that data. The app does not sync saves or best times between Mac, iPhone and iPad.

If you open the privacy-policy website, your browser and the website handle that visit under their own privacy practices. If you email [email protected], your email address and information you choose to provide are used to respond, as described in the Support email section below.

Tony Crayfish Worm Genetics

Worm Genetics runs its simulated experiments on your device. It stores your founder seed, worms, crosses, named strains and mapping work locally so you can resume. The app does not require an account and does not include advertising, analytics or tracking services. It does not send your experiment data to a server operated by Tony Crayfish Productions.

You can start a new experiment to replace the saved one on that device. Mac and iPhone/iPad saves are separate; the app does not sync them. The app opens optional website and support-email links outside the app. Those external services follow their own privacy practices. If you email support, we use what you choose to provide to respond, as described below.

Tony Crayfish Genetics Primer

Genetics Primer runs its educational experiments, animated tour and glossary on your device. It does not require an account and does not include advertising, analytics or tracking services. It does not send your experiment settings or activity to a server operated by Tony Crayfish Productions.

The human-variation explorers use published research data bundled with the app. The app does not ask you to upload DNA, genetic test results or medical information, and it does not analyze your personal genetic data. Experiment sessions are not saved between launches.

Optional scientific and website links open in your browser; email links open your email application. Those external services follow their own privacy practices. If you contact [email protected], we use the information you choose to provide to respond, as described in the support-email section below.

Tony Crayfish Biophysics

Tony Crayfish Biophysics for Mac, iPhone and iPad performs its simulations and plays its bundled teaching recordings on the device. The app does not require an account and does not include advertising, analytics or tracking services. It does not send simulation activity, settings or generated images to a server operated by Tony Crayfish Productions.

Save Image writes a PNG to a location selected by the user on Mac. On iPhone and iPad, it requests permission to add a generated image to Photos; it does not request access to read the photo library. The user controls saved images and any later sharing. Images saved through Photos, iCloud or another storage provider are handled by those services under their own terms and settings.

Optional scientific and website links open in the user's browser, and email links open the user's email application. Those external services follow their own privacy practices. If you contact [email protected], the information you choose to provide is used to respond to your request, as described in this policy's support-email section.

Data used by the apps

Tony Crayfish Biology Hangman uses its built-in word and clue library to run the game. It stores game preferences and progress locally on the device. It does not request access to photos, files, contacts, location, microphone, camera, or other personal content.

Tony Crayfish Worm Measurer reads microscopy images to display images, propose and edit worm traces, and calculate measurements. It saves sessions and settings locally and writes exports to locations you choose.

Tony Crayfish Mosaic processes photographs selected by the user on the device. It uses image content and available metadata, such as capture dates, to create collages and optional date labels. It keeps working copies locally and includes photographs in saved editable projects. The user chooses where to save projects and exports. Optional saving to Photos uses system permission controls.

Tony Crayfish Image Blinder reads the image folders you select, creates copies or converted images in a destination you choose, and writes a local Excel workbook mapping randomized filenames to the originals. It remembers your last chosen destination locally. The workbook is not encrypted and may contain original filenames and paths. Image content or metadata can also contain identifying information.

Collection and sharing

These apps do not send your Worm Genetics experiment data, game activity, simulation activity, settings, generated images, photographs, projects, measurements, sessions or blinding keys to a server operated by Tony Crayfish Productions. They do not include advertising or analytics services, and they do not require an account.

Tony Crayfish Biology Hangman does not collect or share personal data.

Files you export from the other apps remain where you choose to save them. If you share those files, you control that sharing. Keep any blinding key separate from images shared for blinded review.

Files and controls

Tony Crayfish Biology Hangman stores win and loss totals locally. Deleting the app removes this locally stored game data.

For apps that use files or photographs, you choose content through system file and Photos controls on Mac, iPhone and iPad. You can remove locally saved sessions, preferences and exports. Removing an app may not remove files you saved elsewhere. If you choose iCloud Drive or another storage provider, that provider handles the selected files under its own privacy terms.

Support email

If you contact [email protected], your email address and any information you provide are used to respond to your request. Please do not send confidential images or personal data unless needed and authorized. You may request deletion of your support correspondence at that address.

Questions and future apps
