Table of contents
At a glance
- Calculations and local settings differ from server and community features.
- A UUID is a pseudonymous identifier, not a guarantee of anonymity.
- Comments, professional contacts and ratings may be shared with other users.
A brief overview. See the full text below for the scope and details.
Effective date and existing users
This text is issued with effect from 4 October 2026. The Privacy Policy describes processing and does not require blanket consent. New contractual terms apply to existing users only after proper notice and valid agreement or another lawful change procedure; publication alone does not rewrite earlier contracts.
Controller and contact
SilkIdea s.r.o., company number 07990073, VAT ID CZ07990073, registered office: Kosova 1242/1c, Suchdol, 165 00 Praha 6, Czech Republic. Registered in the Commercial Register maintained by the Municipal Court in Prague, Section C, File 311152. Contact: info@silkidea.com; telephone +420 724 672 400.
SilkIdea is responsible for the processing described here. Send privacy questions and requests to privacy@silkidea.com or our registered office.
What we process
Local settings and inputs support calculations and source material on the device. Network requests send necessary technical information to CAserver, such as user identifier, requested airport, time and connection IP address. A random UUID links submissions, ratings and certain entitlements. iOS may retain the identifier in iCloud; Android uses local storage and Google Block Store for restoration. Reinstallation therefore need not create a completely new identity.
Sharing sends note content, airport and service, timestamps, submission and author identifiers, and ratings. Content may include a professional contact’s name and telephone number. Published responses also include raters’ pseudonymous UUIDs and ratings. Other users downloading the material may receive these data; this is not a private message only to SilkIdea.
Purposes and legal bases
We process data necessary for your requested feature to perform the contract. Security, spam prevention, moderation and claim handling rely on legitimate interests in a safe and reliable service, considering effects on the people concerned. Submissions are voluntary; network or sharing features may not work without necessary technical data. Uploaded contacts may come from another user; the person concerned can request correction, erasure or available information about the source.
Rules and a local inappropriate-content model assess text; user ratings also affect submissions. Automation can withhold content or affect publication. Request human review and an explanation at info@silkidea.com. The Terms of Use explain reporting. This does not verify aviation correctness.
Recipients and security
CAserver is hosted by Hetzner Online GmbH in its European region under a processing agreement. Authorised people administer it. Shared material is distributed to app users. Apple and Google operate their respective stores and system services under their own terms, including payments and purchase restoration. We do not receive payment-card details from these stores.
We use appropriate technical and organisational measures to protect transmission and access. A pseudonymous identifier can still link activities and content may identify someone directly. Shared submissions may reach users outside the EEA. A provider processing personal data on our behalf outside the EEA requires appropriate legal safeguards; privacy@silkidea.com can provide information about a particular transfer.
Retention and removal
Published material supports the shared database while current and lawfully published. Removing or hiding a submission in the app may only change an availability flag, without physically erasing the original record, ratings or backup. Request erasure of personal data at privacy@silkidea.com, identifying the submission, airport and information enabling proportionate verification. We may not be able to directly erase copies already downloaded by others.
Failed trial-code attempts record an identifier and IP address to prevent abuse. Records older than one day are cleaned when further attempts fail; this does not guarantee automatic deletion at exactly 24 hours. Ordinary operational logs support diagnostics and security for as long as needed to resolve a particular fault or threat. Non-public or removed content is retained only as needed for moderation, review or a specific legal claim. We review necessity and physically erase or irreversibly anonymise records when the purpose ends.
You can request removal of the entire server identity and linked personal data even without a registered name or email account. After proportionate verification, a request may be fulfilled manually; provide an available ID or details enabling us to locate the records. We do not require unnecessary identity documents. We also check logs, ratings, non-public copies and backups. Where personal data has been made public, we take reasonable steps concerning recipients or other controllers as required by law. We explain any specific statutory exception and further retention period; technical difficulty alone is not a reason for refusal.
Backups and completion of erasure
We use daily Hetzner server backups in seven rotating slots for recovery. With regular daily operation, the cycle therefore covers approximately seven days. This is a server backup, not a separate retention period for accounts, submissions, operational logs or other providers’ data; their retention follows the purposes and rules described above.
Erasure also covers manual technical and migration copies. We retain these only as needed to verify recovery or complete a migration, then remove them unless a specific legal reason requires separate retention. Hetzner’s seven slots do not automatically remove these copies.
If an individual record cannot safely be separated from an immutable backup, we restrict further use and access, establish the earliest deletion date for that copy and reapply the relevant erasures before normal use after restoration. Technical difficulty alone is not a reason to refuse a request or retain data indefinitely. We explain the scope, timing and any statutory exception when handling the request.
Support and legal claims
When you contact us, we process your address, message and information you attach to reply, perform the contract or handle a complaint. For general enquiries our legitimate interest is communicating with users. Send only necessary information. Our mail is hosted directly by IceWarp Cloud on its infrastructure and handled by people authorised by SilkIdea. IceWarp processes mail content to provide the service under its processing agreement: https://myicewarp.com/others/dpa.
We retain ordinary support correspondence while handling it and for no more than 12 months after the enquiry is closed. Necessary evidence of a specific legal claim may be kept separately until the applicable limitation period expires or the dispute is finally resolved. A document subject to statutory accounting or tax retention is kept for that period; this is not a reason to keep all correspondence.
IceWarp may use subprocessors. Its DPA requires appropriate safeguards for transfers outside the EEA, such as an adequacy decision or standard contractual clauses. Contact privacy@silkidea.com for recipient information and a copy of applicable safeguards. Our seven-day Hetzner server-backup cycle is not the retention period for the inbox or IceWarp backups.
Your rights
You may request confirmation of processing, access and a copy, correction, deletion, restriction and portability to the extent provided by applicable law. You may object to processing based on legitimate interests. You can withdraw consent for future processing without affecting the lawfulness of earlier processing.
Write to privacy@silkidea.com. We verify only information reasonably needed to handle the request; do not send passwords or secret keys. Requests are normally free. Under the GDPR we generally respond within one month and explain any permitted extension, its reason or any refusal. We do not penalise you for exercising your rights. A particular feature may become unavailable if we can no longer process data necessary to provide it.
You may complain to the competent supervisory authority, particularly where you habitually live or work or where an alleged infringement occurred. In the Czech Republic this is the Office for Personal Data Protection, https://uoou.gov.cz/. You do not have to resolve a matter with us before seeking regulatory or judicial protection.
Users in other countries
The contact process above is available to users in every country. Mandatory local rights prevail. Where your US state privacy law applies, you may also use an authorised agent and ask privacy@silkidea.com to review a denied request; we respond within the applicable deadline and explain further remedies. We do not sell data or share it for targeted advertising across services. This document describes the categories, purposes, recipients and retention.
Users in the United Kingdom may contact the ICO https://ico.org.uk/, in Switzerland the FDPIC https://www.edoeb.admin.ch/ and in Brazil the ANPD https://www.gov.br/anpd/. Local rights, including information about recipients, the consequences of refusing consent and review of decisions, remain available. The page language does not determine your residence or the scope of your rights.
Policy updates
The date and version appear above. We explain material changes and provide appropriate notice, for example in the app or on the website before new processing begins. Editing this page does not authorise a new purpose requiring consent. Previous versions are available on request.
Language versions
We prepare these documents in Czech and provide translations. If language versions of the same document and the same version conflict, the Czech text prevails to the extent permitted by applicable law. This does not affect mandatory local language requirements, mandatory consumer rights, interpretation of ambiguities in the consumer’s favour or information reasonably relied on when concluding the contract. This clause does not give priority between different dated versions and does not override the separate Apple Standard EULA or Joinly documents.
Version 1.0. Effective from .
