AI has changed how people plan trips. Tools such as Mindtrip, Layla, Google Gemini, Wanderlog and MonkeyTravel can turn a few details into a day-by-day itinerary. However, every great itinerary starts with personal details, and those details travel further than most people realize.
Think about what a typical planning chat contains. You share when you’re leaving, where you’re staying and who’s coming with you. In other words, you describe exactly when your home will be empty and where you’ll be instead.
None of this means you should stop using AI. Instead, it means planning with a few simple habits, and using the right tools on the networks you connect to along the way.
What AI Trip Planners Learn About You
| What you share | Why it matters |
|---|---|
| Exact travel dates | It reveals when your home is likely to be empty |
| Hotel names and addresses | It pinpoints where you’ll sleep each night |
| Passport, visa or ID numbers | These are high-value details for identity fraud |
| Budget and loyalty program numbers | They reveal spending habits and linked accounts |
| Names and ages of travel companions | They expose details about family members, including children |
Most of these details feel harmless on their own. Together, though, they build a detailed picture of your life, your routine and your absence from home.
What Proton’s 2026 Survey Reveals About AI and Privacy
In September 2026, Proton published a survey of 4,014 chatbot users in the United States, the United Kingdom, France and Germany. The findings show a clear gap between what people feel and what they actually do.
| Finding | What it means for travelers |
|---|---|
| Two-thirds of users have shared something sensitive with a chatbot | Oversharing is the norm, not the exception |
| Fewer than one in five highly trust AI companies with their data | Most people share despite their doubts |
| Eight in 10 would be more likely to use a privacy-focused chatbot | Private AI options are in clear demand |

In short, most people already sense the risk. The challenge is turning that instinct into practical habits before the next trip.
What a VPN Does, and Doesn’t, Protect When You Plan
A VPN is one of the most useful travel privacy tools. Still, it helps to know exactly what it covers, because no single tool fixes everything.
| A VPN protects | A VPN doesn’t protect |
|---|---|
| Your traffic on airport, hotel and café Wi-Fi, through encryption | What you type into an AI chatbot |
| Your real IP address and approximate location from websites | Data you hand over when you sign in to an account |
| Your browsing from the Wi-Fi operator and your internet provider | Information you enter on booking or airline forms |
| Your real IP address if the VPN drops, once you turn on the kill switch | Screenshots or files you share with others |
Put simply, a VPN secures the road your data travels on. Meanwhile, careful sharing habits decide what data makes the journey in the first place. You need both.
How Proton VPN Fits Into Your Trip
Proton VPN is based in Switzerland and offers a free plan alongside its paid tiers. Its free plan includes unlimited data, no ads, and the same encryption and no-logs policy as paid plans. Proton connects free users automatically to servers in 10 countries, including the US, Canada, the Netherlands and Japan.
| Travel situation | What to do |
|---|---|
| Checking flights on airport Wi-Fi | Connect to Proton VPN Free before you open any booking site |
| Logging in to email from a hotel network | Turn on the kill switch in the app settings, so your traffic stops if the VPN drops |
| A booking or banking site blocks your connection | Switch to a different server, since some sites block known VPN addresses |
| Protecting a family’s phones and laptops | Upgrade to VPN Plus, which covers up to 10 devices at once |
| Choosing a specific country’s server | Upgrade to VPN Plus for 20,000+ servers in 140+ countries |

For most travelers, the free plan covers public Wi-Fi protection well. VPN Plus then adds speed, server choice, streaming support, the NetShield ad and malware blocker, and Secure Core routing for those who need more.
Lumo: A Private AI Assistant for Trip Planning
Proton’s own AI assistant, Lumo, tackles the problem a VPN can’t solve: what happens to your chats. According to Proton, Lumo keeps no logs of what you ask or what it replies. If you sign in, Proton stores your chat history with zero-access encryption, which means even Proton can’t read it.
Proton also says it doesn’t use Lumo chats to train its AI models. The one exception is an opt-in model called Apertus 1.5, which uses your data only with your explicit consent. In addition, Lumo runs on Proton’s European infrastructure under Swiss privacy law.
One honest caveat applies here. Your prompts still reach Proton’s servers so Lumo can answer them. As a result, the best habit stays the same with any AI: share only what the task genuinely needs.
You can try Lumo for free, either as a guest or with a free Proton account. Signing in with a free Proton account unlocks more prompts and saved chat history, while Lumo Plus adds premium features.

7 Rules for Planning a Trip With AI, Privately
- Keep ID numbers out. Never paste passport, visa or driver’s license numbers into a chatbot.
- Use approximate dates. Say “mid-June for 10 days” while brainstorming, then confirm exact dates only on the booking site.
- Skip the home details. Avoid mentioning your home address or that your home will be empty.
- Check the training settings. Review whether your AI planner uses chats for training, and switch it off where that option exists.
- Protect public Wi-Fi. Connect through a VPN before planning or booking on airport, hotel or café networks.
- Use email aliases. Create a separate alias for each booking site, so a data breach can’t expose your main inbox.
- Clear old chats. Delete planning conversations you no longer need once the trip is booked.
Can You Trust Proton? What the Evidence Shows
Independent evidence matters more than any company’s promises. Proton VPN’s no-logs policy has now passed its fifth consecutive annual audit by Securitum, a European security firm. The 2026 report found no persistent records that would let Proton link a specific user to activity on an audited VPN server. Proton’s apps are also open source, so anyone can inspect the code.
In everyday use, a few simple habits help Proton VPN run smoothly on the road. For example, switching servers solves most website blocks, while choosing the right plan from the start avoids surprises later.
Quick fixes for a smoother Proton VPN experience
| Situation | What to do |
|---|---|
| Before your trip | Test Proton VPN Free at home on each device you’ll travel with |
