Privacy Policy — E88 Guide

Effective date: 30 September 2026.

1. Who is responsible

E88 Guide is distributed through the individual Apple App Store developer account of Andrei-Cristian Romașcu-Radu. The App is operated and monetised by Celeris Software S.R.L., Republic of Moldova, under an exclusive licence granted by Andrei-Cristian Romașcu-Radu.

This policy explains how Celeris Software S.R.L., based in the Republic of Moldova ("we", "us"), handles information in connection with E88 Guide (the "App"). You can contact us about privacy at contact@celeris.software.

The App is an independent setup and troubleshooting guide for E88-family drones. It includes saved guide progress, a manually entered drone profile, preflight checklists, troubleshooting questions and an interactive control-practice diagram. It does not connect to a drone, scan nearby networks, receive live camera video or transmit flight commands.

This policy covers the App. Websites, companion apps, advertising destinations and services that you choose to open have their own privacy practices. No account is required to use the App.

2. Information saved on your device

The App stores the following information locally so that its features work and your choices can be remembered:

The optional Wi-Fi name is text that you enter yourself. The App does not read your connected network name or discover nearby devices. Please avoid entering passwords, financial information or other sensitive information in notes.

We do not operate a server that receives this profile, your notes or your guide progress, and we do not intentionally pass these fields to the advertising SDK. The App has no developer-operated analytics or cloud-sync service. Your operating system may include app data in device backups according to your Apple and device settings; we do not operate those backups.

3. Sharing and contacting us

If you choose Share during troubleshooting, the App prepares a text summary of the issue, your reported checks and relevant manually entered profile details. You choose the recipient or destination using the iOS share sheet. Review the summary before sending it. The App does not automatically send it to us.

If you contact us by email or send us a summary, we receive the information you include, such as your email address, message and attachments. We use it to answer you, investigate the issue and handle privacy requests. Our email provider processes that correspondence as part of providing email services.

4. Advertising and consent services

The App uses Google AdMob to display banner and interstitial advertising and Google's User Messaging Platform (UMP) to manage applicable advertising privacy choices. These services make network requests. Although the guide's own saved information stays on your device unless you share it, advertising and consent services may process information externally.

Depending on the service configuration, region, permissions and privacy choices, Google and participating advertising providers may process IP address and approximate location inferred from it; device or advertising identifiers; device and app information; ad impressions and interactions; crash, diagnostic and performance information; and consent selections or signals. These data support ad delivery, measurement, personalisation where permitted, service operation and fraud prevention.

The App does not request access to your precise GPS location, contacts, microphone or camera for its guide features. Approximate location inferred from an IP address is different from GPS access.

The iOS advertising identifier (IDFA) is available to the advertising SDK only when the relevant Apple tracking permission allows it. Declining tracking permission does not mean that all advertising-related information or network requests stop. Non-personalised or limited ads may still involve data processing, subject to your choices and applicable requirements.

Google's practices and controls are described in the Google Privacy Policy and How Google uses information from sites or apps that use its services. The consent message, where available, provides information about participating advertising providers and their stated purposes.

5. Your consent and tracking choices

Where required for your region and consent status, the App asks Google UMP to display an advertising privacy message. This is not necessarily shown on every launch. Your selections are used to determine which advertising requests may proceed.

When Google requires an in-app privacy-options entry point, open About, sources & privacy → Manage ad privacy choices to review or change the available selections. Where iOS presents an App Tracking Transparency prompt, that is a separate Apple permission. You can also review tracking permission in iOS Settings → Privacy & Security → Tracking, subject to your device settings and restrictions.

You can continue using the guide when you decline tracking or do not allow advertising processing that requires consent. Withdrawing consent does not affect the lawfulness of processing that took place before withdrawal. Changes to app consent settings do not themselves delete information already held by an external provider.

6. Why information is processed

We use on-device information to provide the guide, adapt its instructions to your selections and remember your progress. If you contact us, we use your correspondence to respond and resolve requests. Advertising supports the availability of the App, and consent services record or communicate relevant privacy choices.

Where EU or UK data-protection rules apply, we rely on consent for advertising storage, personalisation or tracking where consent is required. For support correspondence and protecting our services, we rely on our legitimate interests in assisting users and maintaining reliable services, subject to your rights. We may also process information where needed to comply with legal obligations, including responding to applicable privacy requests. Advertising providers identify their purposes and applicable legal bases in their notices and the consent interface.

We do not use your locally saved drone notes or profile to make decisions that have legal or similarly significant effects on you. Advertising providers may use permitted information to select or personalise ads as described in their policies.

7. Recipients and international processing

Information needed for advertising and consent is processed by Google and the advertising providers involved in serving or measuring an ad. If you contact us, relevant information is processed by us and our email service provider. Information you share through the iOS share sheet goes to the destination you select. We may disclose information we actually hold where required by law or necessary to address a legal claim.

Service providers may process information in countries other than your own. Google's information about international processing and applicable safeguards is available in its privacy policy, including data-transfer frameworks. Contact us for information about the handling of correspondence you send to us. We do not upload your saved guide profile to a developer-operated server.

8. Retention and deletion

Local guide data is retained on your device until you change or reset it or delete the App and its app data. Offloading an app may preserve its documents and data. Device backups may retain copies separately until those backups are removed under your device or account settings.

To reset the profile, notes, completed steps, resolved-problem flags and checklist, open About, sources & privacy → Delete my saved guide data and confirm. This keeps your selected app language. It does not reset Google consent records, withdraw a previously shared message or delete advertising information held by a provider.

We keep support correspondence for as long as needed to respond to your request, resolve related issues and meet applicable legal obligations. When deciding how long to keep it, we consider whether the issue remains open, the sensitivity of the information and any applicable legal retention or limitation periods. Information may be kept longer where needed to establish, exercise or defend legal claims. Google and other providers apply their own retention policies to the information they process. See Google's retention information.

9. Your privacy rights

Depending on your location and the applicable law, you may have rights to access, correct or delete personal information, obtain a portable copy, restrict or object to processing, withdraw consent, or complain to a data-protection authority. These rights may be subject to conditions or exceptions.

Contact contact@celeris.software to make a request concerning information we handle or to ask for help identifying the appropriate provider. We may need limited information to verify and respond to a request. We cannot remotely retrieve or erase guide data that exists only on your device; use the in-app deletion control for that data. Google and other providers also offer their own privacy-request channels.

10. Children’s privacy

The App provides device setup information and does not require an age profile or account registration. Children should use drones with appropriate adult supervision and follow the manufacturer’s age and safety instructions. Please do not send personal information about a child in support messages unless it is necessary to handle your request. If you are a parent or guardian and believe a child has sent personal information to us, contact contact@celeris.software so that we can investigate and respond as required by applicable law.

11. Security

Local information is stored within the App's device storage and relies on operating-system protections. Protect your device and backups, and share troubleshooting summaries only with recipients you choose. No method of storage or transmission can be guaranteed completely secure.

12. Updates and contact

We may update this policy when the App, its services or applicable requirements change. The effective date at the top identifies the current version. Where a change requires additional notice or consent, we will provide it as applicable.
