Colossal Climbers · Privacy

Your progress. Your choices.

Saved expeditions and history stay on your device. Optional gameplay analytics, Game Center, Apple, TestFlight and support process the information described below.

Updated 20 September 2026 · The app is named Climbers on your Home Screen.

About this policy
Colossal Climbers is a game from Nesia, the independent studio of Mehdi Doghri in the United Kingdom. The app appears as Climbers on your Home Screen. This policy covers solo World 1 in version 1.0, local saves, Game Center, optional analytics and support. World 2 and co-op are coming soon and are not playable in this release. Analytics availability depends on your app version and configuration; collection requires your choice to share. No Nesia account is required.
Progress stored on your device
The app keeps settings, local best results and recent run history on your device. History includes the mode and course, number of players, completed stages or rooms, coins, dates, outcome and timing. It keeps up to 100 recent run entries across the device. Solo Expedition keeps a separate checkpoint containing the explorer, lives, coins, completed stages and timing, so you can continue from the latest saved campsite. There is no Nesia cloud service for these records.
Separate Game Center and offline records
When you start a run, the app uses either your Game Center player identifier or an offline device identity to keep history and checkpoints separate. The local owner key is a hash of the Game Center identifier, not your Apple Account password or email address. Changing accounts does not transfer a saved expedition or history. This separation is a local app feature, not cloud backup or a separate device login.
Game Center and achievements
The app requests Game Center authentication at startup. Solo Expedition and Practice remain available without signing in. Apple supplies a game-specific player identifier and display name for Game Center features. Eligible solo Expedition milestones are stored locally for the associated Game Center account and reported to Apple when available. Switching accounts does not transfer pending achievements. Version 1.0 is solo-only; it does not connect a multiplayer party.
Ranked times
Eligible Ranked runs submit milestone times and a leaderboard identifier to Apple’s Game Center. These are associated with your Game Center profile and may be visible on leaderboards. Local history and campsite checkpoints are not uploaded as cloud saves. Practice, co-op and continued campsite runs do not submit Ranked times. Apple processes Game Center activity under its own Game Center privacy information; you can manage Game Center in device Settings.
Optional gameplay analytics
If you choose Share or enable Share gameplay data in Settings, the game sends GameAnalytics play sessions, stage progress, retries, modes and technical outcomes, with a random installation identifier, device model, iOS version and app version. GameAnalytics receives your IP address and derives country information. These records help us understand and improve the game. The identifier links events from the same installation; the data is not anonymous. We do not include your name, Game Center identifier, party codes or saved-game files in these analytics events.
Your analytics choice
Sharing is optional and does not unlock or restrict World 1, game modes or saves. Collection stays off until you choose to share. You can turn sharing off in Settings. This stops future collection, clears unsent app-managed events and cancels the app’s current analytics request; it cannot retract a request already received by GameAnalytics. Unsent events are stored on the device for up to seven days, within limits of 4,096 events and 4 MiB, and can be sent after reconnection or a later app launch. Expiry, storage limits and interrupted submissions can cause events to be discarded. This queue is separate from gameplay saves. The game stores your choice, disclosure version and the time of your choice locally. Private development and TestFlight analytics use a separate QA project from the App Store project.
Analytics retention and deletion
Turning sharing off or deleting the app does not delete analytics already held by GameAnalytics. Its published data-processing terms describe different retention periods for raw data, warehouse data and retention lookups; the applicable agreement and data category determine the period. Email support@nesia.studio to request access or deletion. Nesia handles these requests manually and coordinates with GameAnalytics; you do not need a GameAnalytics account. We may ask for your existing analytics support ID and enough information to verify your request. We will tell you the outcome after receiving confirmation, including any information that must be retained.
Finding an existing analytics reference
In versions with analytics support controls, open Settings and choose Show analytics support ID. If an existing ID is available, Copy analytics support ID copies it together with its QA or Production channel for a private support request. Showing or copying does not turn sharing on, generate a new ID or delete data. If the reference is unavailable, contact support. Do not enable sharing just to create a replacement ID. Keep the ID out of public posts and screenshots. Possession of an ID alone does not verify a deletion request.
Advertising and device permissions
Nesia does not include an advertising network in the game or use gameplay analytics to target advertising. The app does not request your camera, microphone, contacts, photo library or device location. Country derived by GameAnalytics from an IP address is separate from device location permission. Game Center, Apple diagnostics, TestFlight and support processing are described separately in this policy.
Apple diagnostics and TestFlight
Apple may provide app diagnostics under your device’s sharing settings. In TestFlight, Apple automatically collects crash and usage information and shares it with the developer; feedback you choose to send may include screenshots, comments and contact details. If you were invited by email, Apple also makes your invitation name and email address available to the developer. These identity fields are not shown for testers who join only through a public link. We use this information to investigate issues and improve the game, retaining it only as needed for those purposes and applicable obligations. See Apple’s TestFlight privacy information.
Backups, retention and deletion
App data may be included in an Apple-managed device backup, depending on your settings. Nesia cannot access that backup or restore a lost local expedition for you. A checkpoint is replaced by a later campsite save and retired on game over, victory or confirmed replacement by a new expedition. Recovery copies of replaced or damaged saves may remain in local app storage until that app data is removed; they are not offered as playable expeditions. Delete App removes its local data; Offload App keeps it. Device backups and Apple’s Game Center or TestFlight records are separate, so deleting the app does not automatically remove those copies or leaderboard records.
Email support
If you email support@nesia.studio, we receive your email address, message and any attachments you choose to send. We use correspondence to answer your request and resolve issues, and keep it only as needed for that request and applicable obligations. We do not use support messages for advertising. Do not send passwords, payment details or a full device backup.
This website
Opening a help or privacy page does not attach your run history or checkpoint. This site uses GitHub Pages, which records visitor IP addresses for security. Nesia adds no analytics scripts or advertising cookies to these pages. Apple and GitHub operate their own services under their privacy terms.
Your questions and requests
Email support@nesia.studio to ask about personal data held by Nesia or request access, correction or deletion. We may need enough information to identify the correspondence or feedback concerned. Manage Apple-held information through Apple’s Data and Privacy service. We will update this page when the game’s data practices change. Last updated: 20 September 2026.
