Contrast Cycle Timer
Launch a guided hot-to-cold shower cycle with one tap. Each exposure phase is timed for you, so you can close your eyes and simply breathe through it.
IceFishnet Tone turns contrast showers, frozen infusion blocks and quick cold-water refreshes into one structured morning ritual — timed, tracked and mapped in a single local space on your device.
No fluff, no dashboards you never open. Just the tools that keep a cold-tone routine alive on the days motivation runs thin.
Launch a guided hot-to-cold shower cycle with one tap. Each exposure phase is timed for you, so you can close your eyes and simply breathe through it.
Track how many nutrient-rich ice blocks are left in every tray. Know at a glance when the berry cubes are running low before the morning you actually need them.
Store your custom flavor-infused prep recipes — herbal blends, citrus peels, mint shards — and pair each frozen block with the hot infusion it was made for.
Short, repeatable splash sessions for the moments between meetings. A 30-second reset that pulls you back into focus without a full routine.
See your whole week in one glance. Which mornings held, which slipped, and how the rhythm is trending — no scrolling through logs to find out.
Every completed practice converts into a growing streak you can actually feel. Momentum becomes visible, and skipping a day starts to cost something.
This is the contrast cycle exactly as it runs in the app: warm phase, cold phase, three rounds, one long cold finish. Press start and follow the ring — the whole sequence is driven right here in your browser.
IceFishnet Tone came out of a simple frustration: vitality habits are easy to admire and hard to keep. So we built the structure we were missing.
We are a small independent studio of cold-exposure practitioners, designers and stubborn early risers. We spent years chasing morning energy through half-remembered routines and scattered notes, and eventually decided the ritual deserved a proper home — one clean, local space instead of five apps and a paper list on the fridge.
Our mission is to make consistent vitality feel structured rather than heroic. Cold refreshment, daily contrast routines and natural energy boosters shouldn't collapse the moment your schedule gets loud. We turn those practices into a rhythm you can actually follow, with timing that guides you instead of a checklist that scolds you.
What you get is complete clarity over your daily refresh routines: interactive countdown timers launched with a single tap, contrast phases paced for you, frozen tray stock kept in view, infusion recipes organised where you'll find them, and habit consistency visible at a glance. No hesitation, no guesswork — just the next step, already prepared.
What makes it valuable is what we deliberately left out. There is no account to create, no analytics watching your mornings, no feed competing for the attention you just sharpened. Your streaks belong to you, your data never leaves the device, and every screen exists for exactly one reason: to get you into the water and out into the day.
Cold on the skin. Fire in the day. Nothing in between.
IceFishnet Tone is built as a fully offline, on-device application. We do not collect, store, transmit or sell any personal information whatsoever. There is no server behind this app holding your mornings — everything you create lives on your own device, under your own control.
None. IceFishnet Tone does not collect any personal or identifying information. There are no user accounts, no sign-up screens, no names, no email addresses, no phone numbers, no device identifiers, no location or GPS data, no advertising IDs, and no analytics or usage telemetry of any kind.
Everything you enter while using the app — contrast shower schedules, cold exposure phase durations, timer presets, frozen tray and ice block stock counts, flavor-infused prep recipes, face-refresh sessions and your habit streak history — is written directly to your device's local storage. It is never uploaded, mirrored or read by us, because there is no mechanism in the app capable of doing so.
Since no information is collected, there is nothing for us to use. We do not process, profile, analyse, aggregate, monetise, rent or sell any data. We do not build behavioural models from your routines and we do not share anything with advertisers, data brokers or partners.
All calculations — streak counting, cycle timing, consistency summaries, tray inventory totals — are performed locally on your device, in the moment, purely to display results back to you.
Your content is stored exclusively in the app's private local storage area on your device. IceFishnet Tone operates without cloud storage, without remote databases and without backend servers. We maintain no infrastructure that receives, queues or retains user content.
Because storage is local only, your recipes and streaks are not synchronised between devices, and we are unable to recover them for you if the device is lost, reset or replaced.
IceFishnet Tone integrates no third-party services. There are no analytics platforms, no crash reporting SDKs, no advertising networks, no attribution or marketing trackers, no social media integrations and no embedded external content.
The app makes no outbound network requests for the purpose of transmitting your information, so no third party is placed in a position to receive it.
The strongest protection we can offer is architectural: data that is never transmitted cannot be intercepted, and data that is never stored on a server cannot be exposed in a server breach. Your routine information stays inside the app's sandboxed local storage, protected by the operating system's standard application isolation and by your device's own lock screen, passcode or biometric security.
We recommend keeping your device software current and enabling device-level encryption for an additional layer of protection.
IceFishnet Tone does not knowingly collect information from anyone — and that includes children under the age of 13. Because the app collects no personal data from any user regardless of age, there is nothing for a parent or guardian to request access to, correct or have deleted from our side.
This approach keeps the app aligned with the Children's Online Privacy Protection Act (COPPA) and similar frameworks by removing data collection entirely rather than managing it.
You hold complete control over everything the app holds. You can add, edit or delete any timer preset, tray count, infusion recipe or streak entry at any moment directly inside the app.
To remove all app data permanently, simply uninstall IceFishnet Tone. Deleting the app removes its local storage along with it. Since we operate no accounts, no cloud profiles and no server-side backups, there is no residual copy left anywhere once the app is gone from your device.
We may revise this Privacy Policy from time to time to reflect improvements to the app or updates to legal requirements. When we do, the Effective Date shown at the top of this page will be updated accordingly, and the current version will always be published here.
Our privacy-by-design commitment will not be quietly reversed: if the app's data practices were ever to change materially, we would state it plainly in this document.
If you have questions about this Privacy Policy or about how IceFishnet Tone handles information, reach us at privacy@icefishnettoneapp.com and we will be glad to explain anything in detail.
