User Agreement

Revision date: 2026.09.18

This agreement is published in English for all interface languages.

This User Agreement (the “Agreement”) governs the use of the visa-vis mobile application for iOS and its web version, provided as a PWA (together, the “App” or the “Service”).

Rightsholder and operator of the Service: Aleksei Sinkov
Email: ao.sinkov@gmail.com

App identifier: app.visavis.ios

By installing, launching, or using the App, the User confirms that they have read this Agreement and accept its terms.

1. Definitions

User — a natural person using the App.

Service — the visa-vis mobile application for iOS and its web version (PWA), which provide the User with tools for the local tracking of trips, passports, visas, stamps, tickets, and related data.

User Data — information that the User independently enters, imports, scans, or otherwise saves in the App.

Reference Data — information about visa rules, permitted length of stay, visa regimes, passport requirements, and other restrictions, whether built into the App or downloaded separately.

2. Subject of the Agreement

2.1. The Service provides the User with information and reference services for independently tracking trip history and working with information about passports, visas, permitted length of stay, and tickets.

2.2. The Service is designed for the convenient storage, structuring, and calculation of information and is not a government information resource, travel agency, immigration authority, consulate, law firm, or other official body that makes decisions regarding entry, exit, visa issuance, or permission to stay.

2.3. The Service does not issue visas, entry permits, or stay permits, and does not make decisions regarding the ability to cross any state border.

2.4. Use of the Service does not replace the User’s independent verification of the requirements of the relevant government authorities, border services, consulates, embassies, airlines, and other competent organizations.

3. Features of the Service

Depending on the version of the App used, the User may have access to the following features:

3.1. Passports and trips

The User may:

  • store data for up to two passports;
  • enter name, citizenship, country of residence, and passport issue/expiry dates;
  • add trips and entry/exit records;
  • enter country, city, mode of transport, border crossing point, notes, and intermediate stops;
  • bulk-import stamps;
  • mark open (ongoing) trips;
  • receive a warning about an upcoming passport expiry.

3.2. Visas and stay limits

The User may:

  • create records for their own visas;
  • use built-in visa-regime templates or create custom ones;
  • enter visa validity period, number of entries, day limit, and the rolling window used for the calculation;
  • calculate length of stay based on entered trips;
  • use calculations related to rules such as 90/180;
  • obtain a calculated recommended departure date;
  • use a “what if?” calculator;
  • receive warnings about a possible limit overstay;
  • archive completed visas.

3.3. Map and statistics

The Service may display a schematic world map based on the User’s trip data and generate statistics, including number of countries, days of stay, and calculated distances.

The map is not a navigation system and does not use GPS or the User’s geolocation.

3.4. Tickets and boarding passes

The User may add ticket and boarding pass information:

  • manually;
  • from booking text;
  • from Apple Wallet .pkpass files;
  • by scanning a barcode with the camera;
  • from a photo.

Where the necessary data is available, the User may create a trip record based on a flight.

3.5. Additional features

The Service may provide:

  • interface language switching (available languages: English, Russian, Ukrainian, Turkish, Kazakh);
  • calculation of days spent abroad (90 / 180 / per year / all-time, with a separate reference indicator at 183+ days);
  • local achievements and badges;
  • reference information on “passport strength”;
  • export of trip history for the preparation of visa applications, including in formats aligned with common visa procedures (for example, Schengen, DS-160, UK) — subject to the limitations set out in Section 4 of this Agreement;
  • backup of data via a self-initiated JSON export;
  • import of previously exported data;
  • clearing of trips, visas, and tickets. Such clearing does not affect the User’s profile and passport data unless the User separately deletes it by other means;
  • demo data.

Demo data is used solely to familiarize the User with the interface, is overlaid on top of the User’s data for preview purposes, and does not modify or overwrite data entered by the User.

3.6. Reference catalogs (optional)

By default, the App includes a built-in set of stay rules sufficient for tracking trips, stamps, visas, and tickets without an internet connection.

Additionally, where an internet connection is available, the User may optionally download:

  • an extended catalog of visa rules;
  • a slice of the visa-regime reference database limited to the passport(s) selected by the User.

Downloading additional reference catalogs is not required for the basic use of the Service. Without an internet connection, the Service relies on data previously saved on the device and on the built-in rules.

4. Informational Nature of the Service

4.1. All calculations, recommendations, dates, warnings, limits, and other information displayed by the Service are informational and for reference purposes only.

4.2. In particular, calculations of:

  • length of stay;
  • the permitted number of days;
  • the recommended departure date;
  • rules such as 90/180;
  • the number of entries used;
  • visa validity periods;
  • other visa- and immigration-related restrictions

do not constitute legal advice, an official interpretation of the law, or a guarantee of the User’s right to enter, remain in, or leave any territory.

4.3. The User must not rely solely on the Service’s data or calculations when making decisions about travel, purchasing tickets, crossing a border, applying for a visa, extending a stay, or taking any other legally significant action.

4.4. Before travel and before crossing a border, the User independently verifies the current requirements against the official sources of the relevant state, including, where applicable:

  • official government websites;
  • consulates and embassies;
  • border and immigration authorities;
  • official visa application centers;
  • the official requirements of the carrier.

4.5. Even where the Service contains a corresponding rule or calculation, the User must take into account the possible existence of additional conditions, exceptions, special regimes, and individual circumstances.

5. Currency and Completeness of Information

5.1. Visa, immigration, border, and other rules may change without prior notice.

5.2. Reference Data, whether built into the App or downloaded separately, may be:

  • incomplete;
  • inaccurate;
  • outdated;
  • inapplicable to the User’s specific situation;
  • changed after the time of its publication or update.

5.3. The Service does not guarantee that the information it contains reflects, at any given moment, the latest changes in legislation or administrative practice.

5.4. Additional catalogs and updates referred to in Section 3.6 may be provided separately. The absence of an internet connection does not prevent the use of data already saved on the device; however, such data may also become outdated.

5.5. Where there is a conflict between the Service’s information and the official requirements of the relevant government authority, the User must follow the current official requirements.

6. User Responsibility

6.1. The User is solely responsible for the accuracy of the data they enter.

6.2. In particular, the User independently verifies:

  • the accuracy of entry and exit dates;
  • the accuracy of passport data;
  • visa validity periods;
  • the number of entries used;
  • applicable stay limits;
  • the availability of necessary permits;
  • document requirements;
  • the rules of the specific country and specific route.

6.3. An error in the source data may result in an incorrect calculation. The User understands and accepts this risk.

6.4. The User independently makes decisions regarding travel, crossing borders, submitting documents, and complying with visa and immigration requirements.

7. No Guarantee of Entry or Stay

7.1. Holding a valid visa, meeting a calculated limit within the Service, or receiving a positive calculation result does not guarantee admission to the territory of any state.

7.2. Decisions regarding entry, the permitted length of stay, passage through border control, and other related matters are made by the competent government authorities and/or the carrier in accordance with applicable rules.

7.3. The Service is not responsible for the decisions of government authorities, border services, consulates, carriers, or other third parties.

8. Data Storage

8.1. As a general rule, the App operates offline, and the User’s data is stored on the User’s own device.

8.2. Account registration is not required to use the Service’s core features.

8.3. The Service does not provide cloud synchronization of data between devices unless such a feature is expressly stated for the relevant version of the Service.

8.4. The Service does not use advertising trackers or analytics, unless otherwise expressly stated in the current Privacy Policy.

8.5. The User is solely responsible for the security of their device and for access to the data stored on it.

8.6. If the App is deleted, the device is reset or damaged, or other circumstances result in the loss of local data, recovery of that data may not be possible.

8.7. A backup may be created by the User via the export feature. The User is solely responsible for storing the exported file and protecting it from unauthorized access.

9. Device Permissions

10.3. Reminders are a supporting feature and do not guarantee timely delivery.

10.4. Delivery of a reminder may depend on device settings, the operating system, the calendar application used, power-saving modes, granted permissions, and other technical circumstances, including those beyond the Rightsholder’s control.

10.5. The User is not relieved of the obligation to independently monitor document expiry dates and legal requirements.

13.5. Nothing in this Agreement limits the Rightsholder’s liability to the extent such limitation is prohibited by applicable law.

14. Third-Party Services and Sources

14.1. Certain features may rely on data, formats, or technologies provided by third parties.

14.2. The Service may display reference information obtained from external sources. The presence of such information in the App does not mean it has been officially confirmed by the relevant government authority.

14.4. The additional reference catalogs referred to in Section 3.6 may be compiled from open and/or aggregated third-party sources of visa-requirement data.

15. Privacy

15.1. The processing of personal data and other privacy matters are governed by a separate Privacy Policy, which forms part of the rules for using the Service.
